My visit to the Aaudio Imports this year marks my fourth annual excursion to this wonderland that is also home to Brian and his lovely wife Debra and daughter Sarah. Each year, Brian injects new excitement into this hobby by demonstrating products that sets no precedence in performance and uniqueness. The highlights of my past visits included auditions of his Acapella Triolon Excalibur loudspeaker system in 2008 and 2009, and the Acapella High Violon IV in 2010.

The $211,000 Triolon Excalibur has been my dream loudspeaker ever since my first visit and each subsequent encounter of it at the CES and RMAF conjured up the same sweeping experience I had during my stay at Brian’s home. Being the busy body that he is, Brian made another breakthrough in his product makeup yet again this year by importing the only other loudspeaker company on this Earth to possess expertise in ion plasma tweeter design, Lansche. The main speaker being demonstrated in the Aaudio Imports showroom is the $100,000-per-pair No.7 in the Black American Walnut Satin finish:

Frequency Response:
25Hz-150kHz, ± 3dB

Sensitivity:
92dB/1W/1m

Impedance:
6.8Ω nominal, 4.9Ω minimum

Maximum level:
114dB/1m

Drivers:
1 x 0.3-inch Corona Plasma tweeter
2 x 4-inch Audio Technology midrange
4 x 8.7-inch composite glass fiber/polyester fabric cone, coated

Crossover frequencies:
200Hz/2.5kHz

Dimensions:
69 H x 17 W x 24 D (inch)

Weight:
286 lbs. each

According to Brian, the original individual inventor of the ion plasma tweeter issued two patents, and they were bought up by Acapella and Lansche. Per Brian, while Acapella’s ion tweeter has remained largely unchanged all these years, the Lansche design has seen considerable technological updates over the years. In contrast, while the most affordable ion tweeter-equipped Acapella model retails for $51,000 the pair, a $26,000 pair of the Lansche model No.3 in Satin Veneer finish also features the same Corona plasma tweeter of the $100,000 No.7, this time accompanied by an 8-inch, coated paper cone woofer in a ported cabinet. Audiophiles rejoice!

Across the room from the No.7 was a pair of the No.5.1, complete with an all-BMC system, comprising the BDCD1 CD-Beltdrive Player/Transport ($5,990), DAC1 PRE Digital-Analogue Converter with DIGM+PREAMP+HIGH RES USB ($6,290) and M1 monoblocks ($7,790 each).

The BDCD1 connects to the DAC1 PRE through a proprietary system called Superlink, in which four supplied 75Ω BNC cables carry left/right clock, bit-clock, digital music data from the transport to the DAC, while the fourth BNC cable sends the master clock signal from the DAC to the transport. BMC’s expertise in belt-drive CD transport hails from its OEM productions for CEC, and the new belt-drive design in the BDCD1 features a 50-micron precision bearing. The CD is to be put to the flat underside of the clamp and then placed onto the spindle together. A transport-only version retails for $4,990

The DAC1 PRE packs more innovations than its price suggests. Firstly, two Burr-Brown 24-bit/192kHz PCM1792 DAC chips with current output are coupled to fully balanced I/V converters. The 4-cable Superlink design purports to rid the sonic presentation of coloration induced by common sample rate converters, thus producing the purest-sounding upsampling operation. Available upsampling rates are “Low” at 32fs, and “High” at 128fs. BMC claims the former to have “a more dynamic and detailed presentation, while ‘High’ is softer and smoother.” Selectable digital filter options include “Flat” for frequency response optimization and “Pulse” for best dynamic response and minimized pre- and post-ringing. The large round knob up front controls the BMC DIGM (Discrete Intelligent Gain Management) volume control system. BMC claims lossless volume adjustment in sixty-six precise 1dB increments. The upsampling rate selector, digital filter and volume can all be controlled via the remote. Fun!

The DAC1 PRE also features a dedicated USB digital input that is activated by a free custom driver program to be installed on your computer. My audition of the Lansche No.5.1/BMC system entailed the use of the CD transport and the DAC.

With me sitting 10.5 feet away from each ear to the corresponding speaker, with 9 feet from my ear to the back wall, the No.5.1 were spread 9 feet apart, 4.5 feet away from each side wall, and 5 feet to the front wall. This is my first encounter of a plasma-tweeter speaker system with all dynamic drivers and no horn, and the result was very satisfying. For horn aficionados, there is no substituting an Acapella horn. But for the adventurous, the high-outputting nature of the No.5.1’s two 8.7-inch coated, composite glass fiber/polyester fabric cone woofers were the first surprise element in the speaker’s sonic makeup for pumping out fulsome but judicious levels of bottom-end notes. To my ears, the kind of weight and scale produced by these two 8.7-inch woofers qualifies them as a solid contender among similarly priced competitions. Even more fortuitous was how the Audio Technology midrange complemented the Corona plasma tweeter.

I had a prolonged exposure to another pair of speaker system that featured two, larger-diameter version of the Audio Technology midrange, the $35,500 Rockport Technologies Mira Grand II. To this day, I can still recall the sumptuous tonal texture of instruments and vocalists that the Audio Technology midrange imparted. The Lansche No.5.1 exhibited the familiar tonal richness, this time via a 4-inch AT midrange. But as opposed to the volume of output of the two Rockport midrange, the Lansche’s lone midrange presided over the twin woofers with surprising ease. Not only was it able to place pianos and violin groups on the same playing field with incredible, differentiating dynamics and finesse, the No.5.1 was able to throw very convincing portrayals of the physique of the instruments onto the stage as well. There are plenty of midrange driver choices for different design budgets; but there aren't too many to choose from if the midrange is to complement one of the most exotic tweeters in history.

Whether it was Acapella’s or Lansche’s, I haven’t heard any other tweeter design traversing the upper-mid to top-end so effortlessly, floating over the vast, complicated sonic landscape faster and cleaner than any material-based design. Regardless of type of diaphragm material used, be it diamond or carbon or ceramic, all driver designs energizes that thin layer to vibrate and excite the air. The result will always be an inherent coloration native to the diaphragm used as well as loss of energy, however minute. The Corona plasma tweeter, on the other hand, energizes the air directly. I look forward to the day when Lanshce comes out with a full-range plasma driver! An illuminated switch at the back of the speaker cabinet turns on the power to the plasma tweeter, which is plugged into the wall.

For the readers among us sporting deeper pockets and a medium-to-large listening rooms, a more immersive listening experience awaits in the form of the $100,000-per-pair No.7. To my ears, the five-foot-nine Lansche delivered consistently one of the most definitive musical high-end audio experiences I've encountered. Unlike the Acapella Triolon Excalibur that reinforces the most spectacular horn speaker experience via its large lower-midrange horn, plus the iconic ion tweeter and a column of four woofers nonetheless, the Lansche No.7 harkens back to the dynamic drivers system in its most explicit expression.

First, some system details. Situated 9 feet apart from each other, 3 feet from the back of the speaker to the wall behind it, 4.5 feet from edge of each speaker to side wall and 12 feet from front of speakers to my ear, the No.7’s were driven by a complete Ypsilon system. It includes the CDT100 CD player/transport ($26,000), the DAC100 tube DAC ($29,000), the PST100 MKII preamplifier ($37,000) and last not least, the Aelius monoblocks ($36,000 the pair). It is a hybrid amplifier, inputting via a pair of Siemens C3g input tubes with 6CA4 rectifier tubes, and producing 220 watts into 8 ohms via a MOSFET output stage, of which the first 60 watts are in pure Class A bias! The exotic-looking monoblock pumps up its output to 380 watts in to 4 ohms, and 500 watts into 2 ohms. The Aelius features switchable XLR and RCA inputs, has a frequency range of 11 to 75 kHz and weighs 100 pounds.

The beauty of Ypsilon electronics is their use of the Siemens C3g NOS tubes as input tubes, implemented in conjunction with high-compliance solid-state output stages, as exemplified in the DAC100, the PST100 MKII preamplifier and, of course, the power amplifiers. Music by the Ypsilon system took on a force eminently lively and musical, complex and crystal clear, and yet infused with a judicious touch of single-ended triode sweetness, and propelled by such familiar solid-state aplomb as to be fantasy-mayhem inducing.

In the bottom-end, the No.7's performance exhibited a level of prowess and speed I've never experienced in sub-$100k speaker systems. The now-$211k Acapella Triolon Excalibur's woofer towers had superior, unworldly integration to the rest of its horns, yet it wouldn't approach the Lansche in sheer muscle. Deep-riding electric bass notes and wall-shattering tympani roaring are served equally well by both German speakers, diverging primarily in the way the bass notes are produced and the sonic preference of the listener. Again, I felt both speakers would do justice to rock'n roll and orchestral basses at concert volume levels nonetheless. The Lansche, however, seems to push the bottom-ends harder as augmented by the dual rear ports, and with livelier transients via the smaller, 8.7-inch woofers. This, my friends, is what translates into what I felt was dynamic drivers system in its most explicit expression: Four fast woofers pressurizing the room beautifully. If you and I are lucky, I may even get to experience the $208,000 No.8.1 in the not-too-distant future and write about it, with its two 10-inch paper composite woofers and two 15-inch pure aluminum active subwoofers! It'll be a riot.

The other half of the No.7 story is, of course, the complete sonic experience of the system as a whole. The No.7 is essentially stacking two No.5.1’s head-to-head over each other, but it would not conjure up the sound of the 5.1 en masse. A mere increase in quantity of sound is often the sole benefit achieved by designs I've experienced; the Lansche achieved so much more. Soundstage density was enhanced to such extent that I was at once transported to the front rows on the ground level of concert halls. Height of venue was immaculately reenacted, and volumes of air rushed forward. One could get lost in the mere sonics of the No.7 and not mind the actual musical type being played. Still, meaningful music, like the rumbling of the pipe organ in First Impression Music's K2-version of the Proprius reference disc Cantate Domino sent waves of clean and highly articulate shockwave, complimented very nicely by the solid boundaries of Brian's sound room. Yet, the vast energy of the bottom-end did not drown out the complex midrange and the airy vocalizations of the choir. The privilege of being able to purchase such a loudspeaker system is to be able to experience music so natural in dynamics and uninhibited in dimensionality. There is no greater love than that of the parents for their children, and there is no greater downfall for a man who feels more than just love for music through the most perfect loudspeaker he has discovered and experienced to date. Never mind the expensive electronics that went with it.

The resultant performance is arguably the most tonally musical and dynamically powerful, of both single-ended triode low-output tube amplifiers and steeply-biased pure Class A massive-output solid-state behemoths. And in Brian's system, everything just came together in the most amiable form possible, including the one key element in the chain: the cable systems. Cables are the kind of stuff that you want to forget about once you put them in place. The less you spend on it, the sooner you want to forget about it; especially when you are spending not nearly enough on it to complement your sound system, and you are not proud of it. Anyway you want to see it, there is only the constant reminder that you get what you pay for. In my experience of cable systems, there is no magic carpet ride where some strangely affordable cables can outperform products from reputable, well established brands. It is all about how much we want to compromise and how that compromise manifests itself in our system.

If you choose to build a budget systems, then your focus will not be on ultimate resolution and lifelike dynamics but listenability, and most importantly, getting oneself closer to the music through reasonable means. But if you choose to dispense with considerable finance on your audio system to attain realism in dynamics and resolution, then you must allocate a good portion of that investment in cable systems. Stage III Concepts cables was Brian's reference. His association with Stage III Concepts began in 2001, when he was its U.S. Distributor. In 2008, when Stage III Concepts relaunched its product lines with significant changes, Brian took a listen and signed a contract to be the company's global distributor. Stage III Concepts was Brian's wish coming true for a cable brand that would do his products justice for the many years that I've known him.

On a fine Sunday afternoon, Brian and I visited dealership Audio Limits, where Gene and Darren O'Neal, our hosts, treated us to fine music via a system comprised of a pair of Venture Grand Ultimate speakers ($89,000/pair), BMC electronics and Silversmith cables. The O’Neal’s were playing music in high-resolution format via an Asus tablet with the BMC DAC1 PRE Digital-Analogue Converter with DIGM+PREAMP. The music was a Chinese audiophile track by a female singer against a backdrop of vast instrumental accompaniment. It was recommended to the O’Neal’s by Carlos Candeias, owner of BMC, and was it of demonstration class! The soaring female vocalization was supported by a powerful chorus, and the soundstage was as spacious as the sonic texture was smooth.

Midway through the demonstration, Brian took out his $3,200 Weizhi PRS-6 power distributor and a slew of Stage III Concepts cables; but the O’Neal’s were already using a $6,000 power conditioner. Back into our seats we went, and the soundstage changed from the hollowness of a dome-shaped sound field to one that was wide opened, all the way to the edges of the front walls and beyond. The ceiling of the soundstage was escalated by a story or two seemingly, and the specificity aspect of instrument localization was transformed in such manner, making the sonic performance under the $6,000 power conditioner two-dimensional by comparison.

I am not giving up my Isoclean system of 80A3, Supreme Focus and Super Focus yet; but I am legitimately concerned. Brian, don't expect me to give my full endorsement to your new Weizhi products without a formal auditioning in my system. And they better be superior.

On our drive back to the Ackerman residence, the one lingering thought in my mind was the one product the value of which stood out like Stop signs to me. No, it wasn't the Lansche No.7, although I will declare that they were the most fantastic and musical dynamic loudspeakers I've ever heard. The performance of the No.7 was at once nimble and whispery, while producing dynamics and spatiality of such magnitude as to be awe-inspiring. I did not feel compelled to compare the No.7 to the Acapella Triolon Excalibur during my entire stay, which was the perfect speaker system for me before the Lansche. The fact is the Lansche will now fit into my listening room very, very nicely, with dynamics and bottom-ends that will rival the Acapellas. If I had a huge room and twice the money needed to acquire the Lansche, I would still get a pair of the Acapella TEs, for they do make quite a visual statement first and foremost. Until then, the Lansche No.7 is now my dream speaker.

The thought of the Lansche No.3 became more and more relevant to me. For the first time in audio history, a speaker with plasma tweeter can be had for $26,000 the pair, and it is the same model used by the No.7 and No.5.1. The Corona is accompanied by an eight-inch paper cone woofer, and the system is specified to produce bottom-ends down to 40 Hz, +/- 3 dB. Not having heard it in person, I will not endorse it without reservations, but if the No.7 and No.5.1 are any indication, there is every reason to believe that the floor-standing two-way will impress just as profoundly in a small- to medium-sized room as its larger siblings in correspondingly larger spaces.

And then there is the Ypsilon Aelius push-pull hybrid monoblocks. The reference amplification in my own system is the Pass Labs XA100.5 solid-state Class A monoblocks. They are the closest in handling of low-level resolution and textural delicacy as those from Audio Note UK's SETs with silver transformers and all the precious metal innards, and the Ypsilons are able to make the one proverbial step further than the Pass Labs, albeit at about twice the price, in being the perfect amplification balancing act. At $36,000 the pair, the Aelius monoblocks is the most relevant reference amplification of the highest caliber I have come across.

BMC: Uncommon Execution of New Ideas

by Marc Mickelson | September 29, 2011

y exposure to BMC -- short for Balanced Music Concept -- began nonchalantly enough, with a press release that explained the company's solid-state electronics. All of the products seemed interesting, if not particularly special -- at least at first glance. I wrote a short news story about the line, making a mental note to have a closer look at the sleek digital gear and amplifiers at the Rocky Mountain Audio Fest, the home court, so to speak, of BMC's US distributor, Aaudio Imports.

But Brian Ackerman, the one-man band that is Aaudio, had different plans. He called me a few weeks after the news story posted to tell me more about BMC. "I've been looking for a line like this," Brian beamed, then went on to explain that BMC was actually an offshoot of a well-established German company located for nearly twenty years in China. That company designed and manufactured audio electronics for other brands, most notably CEC, AQVOX and TEAC. Most interesting, Brian told me that BMC manufactures "large runs" of its products, instead of making them to order or building a few dozen at a time. What's "large"? "Hundreds of units," he revealed, this strategy, along with Chinese labor, helping BMC to keep manufacturing costs under control.

The picture became a little clearer, but "special" remained elusive. A few weeks later, Brian called again, asking if I'd be interested in writing about the entire BMC line in one mega review. The rationale was that these products, more than others, deserved to be used together. Brian's reasoning seemed simplistic. Electronics manufacturers always claim that their products work best together. Still, I agreed to do the review, mentally citing synergy as the impetus for the full-system approach. To kick things off, Brian invited me to Denver, where he's located, to meet and talk with BMC's CEO, Carlos Candeias. Background for the review, I conceded, and I was off to Denver.

Carlos Candeias relaxing.

This meeting turned out to be anything but a typical dog-and-pony show, for a number of reasons. The first was Carlos himself -- a trained musician of Portuguese and Spanish descent who grew up and studied audio-electronics design in Germany. He designed each product in the BMC line and knew every detail about their manufacture as well. He was also an astute student of the audio industry and the world economy -- equally at ease talking about power supplies and foreign currencies. His view was unusually global -- in terms of the markets in which BMC products are currently sold as well as his China-by-way-of-Germany company. The conversation was more My Dinner with Andre than The Wall Street Journal, but it was clear that BMC functions in some unusual ways.

While each production run does involve building "hundreds" of each product -- 300 to be exact -- even more unusual is BMC's sales strategy. It's both direct to consumers and supportive of the brick-and-mortar dealer. The idea is to allow dealers to do what they do best -- demonstrate products to local customers -- while cutting down on the competition they engage in with the rise of online selling. BMC makes it attractive for dealers to buy demonstration units, and when sales are made, the company aids dealers again by collecting the funds from the customer, drop shipping, and then paying the dealer -- turning the traditional method of selling audio gear on its head. This approach yields a number of potential advantages, including the protection of list prices. BMC collects the money, so it knows what consumers are paying for its products and it can simply refuse a sale if the price is too low. It takes a special product line to ensure the success of such an arrangement -- one whose perceived value is high enough to give dealers incentive to sell it in this fascinating new way.

Inside the BMC DAC1 Pre.

Putting aside the technical particulars of each product, which I'll cover in my review, the care with which the BMC products are designed and manufactured is truly inspiring. Carlos gave me an in-depth tour of his DAC1 Pre ($6290), which, as its name suggests, is a combined digital-to-analog converter and preamp. The fine points were again unusual: bespoke capacitors, a special circuit-board material, gold circuit-board traces, and a new USB input board with proprietary asynchronous circuit. The cosmetics were stunning and, again, unusual. The faceplate is actually a mirrored panel through which LEDs illuminate to show the product's status, and the chassis consists of a matrix of extruded-aluminum pieces that fit together with exacting precision.

While I was in Denver to see the entire BMC product line and discuss the company with its CEO, the most important part of the trip was hearing everything in Brian Ackerman's well-appointed listening room. The only non-BMC products in use, including cables, were the Acapella High Violincello II Mk II speakers ($83,000/pair) and a Bergmann Sleipner turntable ($54,400) with Ortofon A90 cartridge ($4200). In between were the BMC MMCl phono stage ($3890), the aforementioned DAC/preamp, and a pair of Amp M1 mono power amps ($15,580/pair). Providing the bits was the BDCD1 transport ($4990). While this may seem like a rather pedestrian lineup, the ways in which everything was connected were far from common. The phono stage accepts only balanced input, which makes immediate sense, given that a phono cartridge has an inherently balanced output. More unusual was the Superlink connection between transport and DAC, which splits the digital signal into its constituent parts and sends each on a BNC cable, four of which run between the units.

The view from the listening seat.

However, the connection between the DAC/preamp and mono amps was easily the most novel -- even radical. While it's possible to use XLR-terminated interconnects alone, the BMC amps' Current Injection input allows for special connection to the DAC/preamp. In this case, in addition to the balanced interconnects, there is also a pair of TosLink cables that are for data only and carry no signal. This XLR-and-TosLink arrangement sends the source current from the preamp to the amps, allowing adjustment of system gain within the amplifiers themselves.

While this has some important technical advantages, including a dramatic lowering of distortion, it's what it does sonically that proves its worth. When I was packing my demonstration CD-Rs prior to leaving, I was sure I'd only pull out a couple of them once in Denver. Sitting in the prime listening seat, however, I shuffled through them all, and then started over again, just to discover what the BMC electronics were about and then to hear music that I knew well on this exciting system. The system was absolutely effortlessness at every listening level, redefining the term "grainless" and revealing instrumental timbres with extraordinary purity. My immediate impression, and one that persisted as I listened, was that the system presented more of the music and less of everything else.

I'll end this blog with that bit of wisdom -- or confusion. I will be receiving the BMC system shortly after the Rocky Mountain Audio Fest, and, contrary to my initial thinking, I'm anxious to discover the depths of what does seem like a very special product line.

Stage III Concepts Magnus Prime

I have been an audiophile for some time and have owned several different systems. I made the move from digital to analog only about a year ago and have never looked back. My past systems have included gear from Cary, Sumiko, Raidho and Sonus Faber. I have used top cables from companies like Synergistic, JPS Labs and Nordost.

My current system is built on simplicity. My preamp, amp and phono stage are from Einstein. My speakers are Tidal Piano Cera. My source is an Artemis Labs table, Schroeder Reference arm with a Lyra Titan I. The room is a dedicated room and, while small, has the proper treatment to bring out the potential of my gear.

I recently went on a cable quest upon buying the Tidal Piano Cera. All wiring is kept consistent throughout the system (no mixing and matching). First up was Nordost Valhalla as these were used with my previous set up. I have to say, the Valhalla cables were simply not a fit with the system whatsoever. They were actually tough to listen to. Etched would best describe the overall sound. I would not recommend these whatsoever for anyone who owns Tidal speakers. They were quickly sold and I arranged auditions for 3 other brands – Synergistic, Siltech and Stage III Concepts.

Synergistic – I have to give a shout out to Synergistic’s
customer service. Their local dealer provided a full onslaught of
Tesla cables, powercells and speaker cells. The cables were the correct mix of Tesla series for source and power.

I was a little overwhelmed at first. I have owned these cables before but never this many. Cables, lights, plugs…wow…this was a lot to take in. Given my goal for a simple system, I had my doubts as to whether these were for me. As for the sound, they were a huge improvement from the Valhalla. The soundstage was big (really big). Bass was tight and the etched sound from the top end went away. Good news. I kept them in for some time. Over the period, I could not help but notice one thing. Some pieces of music began to sound a little exaggerated. I spoke with a fellow audiophile about this. The word he used was “Technicolor”. Honestly, they were still really good. But I wanted to find something that I believed was more true to the source. The Tidals are very revealing. Out went the Synergistics (except the powercell and some power cables)….these will stay around for a while. In came Siltech.

Siltech – I used Siltech Prince ics and LS 188 speaker cables. The Siltechs are expensive and I realize that not going to the newer speaker cables may have held them back. But, this was the decision I made based on budget. I kept the Synergistic power products in. I am sure that Siltech makes great cables and that they work well in many systems. To me, they fell flat. The top end seemed rounded off and dull. They were the opposite of the Valhalla and just went too far in the other direction. I did not keep these around too long.

Stage III Concepts -- OK, I was skeptical. I am an avid internet searcher/reader.
I was surprised that I could not find more information on these cables. I have been a customer of the product lines that Brian Ackerman of Aaudio imports represents for some time. Brian originally turned me on to Einstein gear when he was based in Orange County California. He is a knowledgeable guy with an ear (and an eye) for some great gear. Brian sent along Stage 3 Magnus Prime cables for my system, which are second from the top in the line. The Magnus Prime is a silver/palladium alloy cable similar to the more expensive Gryphon. Stage III manufacturers their own “Hyperion” connectors, which look to be very well made and utilize carbon fiber plug housings to eliminate external vibrations. Contacts are pure silver with special ceramic core. Stage III cables are handmade to order.

The first word that comes to mind for me with the Stage III is “true”. Things fell into place with the system. This was by far the best imaging I have had in my system, ever!
My wife came down to the listening room and we put on Miles Davis Kind of Blue. She noted, “It sounds like they are in the room with us”. She was right.

These cables really did everything right in my system. Bass was perfect. The top end was not harsh or rolled off. The pieces fell into place. I am a fan of the “phantom” center sound when you get the voice or instrument dialed in so it sits just above the middle of your room. The Stage III Magnus Prime brought that in spades. I have continued to go deeper into my collection and am now listening to music I had not listened to in a while. These cables are as natural as anything I have ever heard. All I can say is these cables are special. I think it is only a matter of time before more audiophiles discover them.

Absolute Sound/Jonathan Valin CES 2011 Show

Posted by: Jonathan Valin at 12:12 am, January 12th, 2011

Next up was the $80k Acapella High Violoncello II—a larger version of the High Violon with an extra woofer inside its box but the same ion tweeter and distinctive horn-loaded midrange. Compared to previous Acapellas, it seemed to have very little horn coloration, although its imaging was a little vague on the Mario Lanza cut, suggesting a slight lack of coherence. On the other hand, it had absolutely no dynamic compression on the punishing Lanza disc, as you might expect from a low-distortion horn speaker, and very high resolution of inner detail. I would have to say that this was the best Acapella speaker I’ve heard. The electronics were from Einstein.

Weizhi PRS6 AC Distribution

By John Atkinson • Posted: Jan 12, 2011

AAudio Imports' Brian Ackerman holds what must be the world's most expensive AC strip, the Weizhi PRS6. Priced at $3200, the PRS6 is machined from a block of Super Duralumin alloy and features a graphite grounding module. There are no isolating transformers or conditioning circuits, the PRS6 is purely passive. The thinking behind the product, said Brian, is "to get the noise out of the line without changing the sound."

Yes, the Weizhi is a gorgeous piece of audio jewelry but do people really pay $3200 for peace of mind? Brian told me that he is currently shipping 10 units a week, so I guess they do.

Acapella Revises the High Violoncello II

By John Atkinson • Posted: Jan 12, 2011

A highlight of my reviewing year in 2010 was living with and writing about the Acapella High Violoncello II speaker from Germany ($80,000/pair). With its horn-loaded, ionic tweeter and horn-loaded midrange unit, this speaker offered both high sensitivity and some of the most satisfyingly musical sound I have experienced in my room.

Current production has been modified a little compared with the much-traveled samples I auditioned for my review. (They were the same pair I had auditioned at the 2010 CES, Axpona and RMAF Shows.) The drive-unit complement, cabinet, and crossover are all the same, but there is now a greater range of level adjustment for the ionic tweeter and isobaric-loaded woofers. But the sound of the latest version at CES. driven by Einstein electronics, sounded just as I remembered: dynamic, transparent, neutrally balanced, and not a trace of horn colorations.

Stage III Concepts Cables

By Jason Victor Serinus • Posted: Jan 15, 2011

Stage II Concepts, a Pasadena-based company whose products are distributed by Brian Ackerman of Aaudio Imports, has released four newly re-engineered, top-of-the-line cables. All are part of the A.S.P. Reference series (Absolute Signal Purity), and are entirely handmade (including connectors) by Luis de la Fuente. Connectors are made of ceramic with a mixture of special resins to minimize crosstalk between pins, and the entire housing composed of carbon-fiber and epoxy resin. The wire itself is silver-palladium alloy. The A.S.P. Reference interconnect and speaker cable also sport a vacuum dielectric.

On display were the Zyklop power cord ($6000/1.5m), Gryphon interconnect ($5800/1m pair RCA, $6300/1m pair XLR), and Mantikor speaker cable ($13,200/2m pair). Besides digital and phono cables and speaker jumpers, the company sells hook-up wire for components in a variety of gauges. The least expensive, 22 AWG ($66/1.5m) is followed by 17 and 15 AWG ($280/1.5m).

Asked about the cable’s sonic properties, Ackerman replied, “It has no sound at all. It’s probably the closest thing I’ve heard to having no wire. It’s virtually invisible, like a direct connection.”

Visiting Aaudio Imports in November 2010

Constantine Soo

This is the first time I’ve visited the Aaudio Imports’ Parker, Colorado headquarters in the winter months, and in my Californian heart I never thought I would once again wake up to a snowy morning. I lived in a snow-and-ice-laden Chicago for years before moving to California in the early 1990s, and snow in the Coloradoan countryside is incomparably tranquil and clean. For one, the ubiquitous and legendary Californian traffic jamming sessions have no presence here. For those who haven’t laid down roots yet, or who can afford to uproot their current lives, moving to Colorado, to its very affordable and spacious living environment is a no-brainer. Brian made just such an incredible move four years ago to Parker from Southern California.

Each time I visited his beautiful, million-dollar home, I tried to breathe in as much of those 6,000 feet high Colorado air as I can. Now for the fourth time, I must also take in as many of the beautiful fall sceneries of the countryside around Brian’s home as I can. The new Lansche (pronounced “Laaa-n-chay”) speaker line that Brian has picked up and is holding the fort in his reference sound room is another sight and sound to behold; the $80,000 Cubus, the only horn model being offered in the present line, specifically. The No.5 at $35,000-$40,000 a pair and the No.3 at $25,000-$30,000 a pair round up the models in the “Passiv Series”. You wouldn’t believe it even if I told you that the $80,000 Cubus constituted the top-of-the-line of this make, not when Brian Ackerman is the importer. Not when the preceding reference that used to occupy the same space was the $205,000 Triolon Excalibur, now in the MKII version. No, the $80,000-per-pair horn speaker is the second top model in the German speaker maker’s lineup of five, the flagship being the No. 8.1 at $187,000 the pair of the “Semiaktiv Series”. There is also the smaller, No. 4.1 at $55,000-$60,000 in the “Semiaktiv Series”.

All the 550 pounds of each of the No. 8.1’s seven-and-a-half feet tower houses the 0.3-inch CORONA ion plasma tweeter, two 3-inch fabric domes, two 10-inch paper composite woofers and two more 15-inch pure aluminum active subwoofers! With the cutover frequency ranges at 400Hz and 2,500Hz, I already can imagine the power of the speakers with the two 10-inch paper woofers, similar to what the Rockport Technologies Mira Grand II also offers. But the two 15-inch active pure aluminum subwoofers at the 40Hz cutover frequency are causes for celebration, and simply too significant for careless speculation by anyone before hearing it. And the speaker isn’t even in the U.S. yet. My audiophile craving is getting the better of me again.

Lansche Cubus speakers

The CORONA ion plasma tweeter technology used by Lansche is licensed from the same source as the Acapella ion tweeter, albeit at different output capacity. Specifically, the Lansche ion plasma tweeter carries twice the flare output of the Acapella’s. Whereas the Acapella ion tweeter traverses the range of 5kHz to 40kHz, the Lansche CORONA ion plasma tweeter encompasses the 2.5k-150kHz spectrum. A visual inspection from the front of the tweeter confirms the considerably larger flare in the interior center. The 2-foot deep cabinet houses a 19.7-inch long midrange horn, the mouth of which is molded mesmerizingly as part of the one-piece front baffle. The horn and the 18-inch woofer beneath it comprise the two large spheres beneath the ion plasma tweeter.

Because of Aaudio Imports, now for the first time in the history of the audio industry we have a company carrying two loudspeaker lines with ion plasma tweeters. What an auspicious moment this is for all of us; and I am very privileged to have been working with someone the caliber of Brian all these years. There is a third product line, however, that has also created much excitement for Brian. It is the Bergmann turntable line, from Denmark.

For the first time in my visits to the Aaudio Imports headquarters, I was told to bring as many LPs as I can. I have a few hundred LPs altogether sitting on the shelves in my listening room and in my storage room. As I am hauling my laptop as the carried-on, I had to pack the LPs into the check-in luggage. To avoid exceeding the weight limit of check-ins at the airport, I selected eleven LPs and put them inside the Classic Records specialty bag, which is then stacked between layers of clothes in the luggage. Had the TSA opened my luggage for inspection, they would’ve messed up the order in which the contents were arranged for safeguarding the precious LPs.

For your information, I wouldn’t have done it if it were not for Brian’s incessant insistence to experience his Bergmann vinyl setup, in the form of the $54,400 Sleipner airbearing and aircentered turntable & tonearm system. “You gotta listen to my vinyl system. It is the top-of-the-line model, you won’t hear anything better than this.” “Okay, I’ll bite.”

Sleipner is a term from Nordic Mythology. Per the Aaudio Imports website:

“In the Nordic Mythology, Sleipner is the magical eight-legged steed, and the first of all horses.
His name means smooth or gliding. Loki, who gave birth to Sleipner, gave this eight-legged steed to Odin, the supreme of the Nordic Gods, telling him that the horse was the swiftest on earth-and could bear Odin over sea and through the air...”

Brian believes that Bergmann turntables are perfect for me. One, because its cartridge lowering and lifting actions are via a knob at the end of the airbearing tonearm tube casing, thus addressing my tonearm-lowering-lifting-phobia. Two, because he knows the mechanism and precision of the linear-tracking tonearm will capture my imaginations as I use the linear-tracking-like 47 Lab PiTracer CD transport as my reference. Third, because he is confident that the air-supported and air-centered suspension system will be superior to most other turntable systems in isolating itself from vibrations, thus equaling if not surpassing the PiTracer’s highly methodical measures against vibrations.

The Bergmann Sleipner is a belt-driven design, featuring a large, bearing-less, 20-pound platter that rides on air and centered by air, thus inducing no mechanical and friction supposedly. The linear-tracking tonearm also operates on a cushion of air. The vacuum hold-down function is the quietest I’ve heard in similar designs by others; in fact, its outboard vacuum is the only working design that is completely quiet during operation, thus allowing it to be placed on the same equipment rack. Take note, Dyson. Piano black finish and WBT Nextgen RCA silver connectors complete the 110-pound vinyl system.

Whether I was playing the vinyl version of the Proprius Cantate Domino recording or the Angel Sonics 45 RPM disk of Karajan conducting Wagner overtures, the tonal brilliance and richness were more easily expressed by the Lansche Cubus than speakers of other tweeter technology, under the complimentary support of the $26,000 Ypsilon VPS100 valve phono stage, the $37,000 PST 100 MKII tube preamplifier and the $34,000-per-pair Aelius push-pull hybrid monoblock amplifiers. The silk dome tweeter technology of Audio Note UK AN-E Lexus Signature comes closest in shading sophistication and naturalness, while the ring radiator tweeter of the Lumen White Artisan has the lightning-fast transient characteristics of the ion tweeter. Hearing a tweeter doing 2,500 to 150kHz is an event to behold anytime you play music through it, but it becomes an experience the most unreal I can recall when this marvel of a technology can spread the spectrum in the most even-handed manner at the highest of outputs. The soundstage just seemed to continue to develop horizontally and vertically the louder you make the Cubus play. Parameters like ambience and instrument outline developed progressively until the Aaudio Imports reference sound room was overrun summarily in excessive volume by a mad, ignorant writer with a trigger-happy finger and ear-to-ear smile. Compressions at various frequencies that all other tweeters readily displayed in my years of auditions simply didn’t occur with the Lansche Cubus. The real singularity is the compression-free prowess of the Cubus’ Corona plasma tweeter.

The other Lansche model set up in the opposite end of the room, the No. 5, had the same CORONA ion plasma tweeter, this time accompanied by one 3-inch textile dome midrange and two 8-inch composite glass fiber/polyester fabric woofers. With Ypsilon’s $26,000 CDT 100 CD player/Transport at the helm as the CD player and accompanied by the $18,400 Einstein “The Tube MKII” balanced tube preamp and the $11,900 “The Light In The Dark” tube stereo power amplifier, the Lansche No. 5 exhibited closely comparable soundstaging prowess to that of the Cubus, but with no less flamboyance and flare. The twin woofers, however, asserted a punchier and leaner bottom-end than the Cubus, manifesting an instantly gratifying bottom-end. Whereas the Cubus was refined, spacious-sounding and very impressive, the No. 5 carried a higher dosage of audiophile excitement without discounting the quality of overall presentation, including the amazing performance of the CORONA ion plasma tweeter. I thought the Cubus, albeit much smaller than the Acapella Triolon Excalibur, would flex its muscles even more impressively if it were in a larger room than Brian’s sound room. The No. 5, on the other hand, rolled out all the bass juices within the listening room and filled out all sonic parameters very evenly. For half the price of the Cubus, the No. 5 is destined to be the prime choice for most homes except for the largest.

Pictured: Lansche No. 5 speakers, this time with Einstein "The Source" balanced tube CD player.

If this is not reason enough for you to get excited, Brian informed me that an upgraded model, namely the No. 5.1 with a larger, 4-inch Audio Technology midrange will be introduced to replace the original 3-inch. The No. 5.1 will be approximately $5,000 more at around $40,000 for the Satin Veneer pair and around $45,000 for the Piano Black High Gloss Veneer pair.

Brian also substituted the Ypsilon briefly with Lindemann’s latest CD player, the $12,500 825 High Definition Disc Player, and I wrongfully presumed that the Lindemann would be an unlistenable alternative to the Ypsilon. Brian knew that, of course, and with his usual poise and calm, graceful demeanor he once again proved he did know more than I did. For he had told me previously that Lindemann believes the less expensive 825 is so good that it has ended argument about whether CD or SACD to play. Playing the same discs I had put into the Ypsilon CDT 100, I found the new Lindemann to be the smoothest sounding detail-freak machine ever. And it wasn’t even a tube player. The expansive soundstaging of the Lansche No. 5 was not one bit diminished, retaining the fullness and sophistication of instrument portrayal on stage as if the Ypsilon was still holding the fort. Brian was right again.

The Lindemann 825 High Definition Disc Player has the RCA, Toslink and USB inputs, plus RCA and Toslink digital outputs. The player’s USB audio port features a “USB Audio Class 2” audio interface for 24-bit, 192kHz capability. In fact, according to the Lindemann website, the 825 is the first CD player in the world to combine upsampling to 24-bit, 384kHz with a minimum phase filter. More details are available here (Lindemann) and here (Aaudio Imports).

This same player was also used in an inner, smaller sound room, in which a pair of Lansche’s $25,000-$35,000 No. 3 two-way floorstanders were placed. The room measured 12 feet 2 inches long, 11 feet 7 inches wide and 7 feet 6 inches high, and electronics were the Aaron No. 22 solid-state preamplifier and No. 3 solid-state amplifier. Reaching down to 2,500Hz, the No.3’s ion plasma tweeter qualifies as the only ion plasma tweeter available that is also versatile enough for use in two-way designs. Its upward-tilted front baffle also complemented the lower CORONA plasma tweeter and 8-inch paper cone woofer wondrously. With 7 feet of listening space between the front of speaker and the ear, the dynamics, transparency and dimensionality were amazing. Although the perspective resembled a balcony seat looking down onto the stage, the sonic expansiveness remained largely identical to that of the No. 5.

Again, six days came and went too swiftly during my stay at Brian’s place, like last year and the year before that. He was still just as hard working as before, conversing with his dealers and manufacturers on the phone all day, leaving me to the fun of sampling his new products. Throughout all these years, Acapella Audio Arts speakers and Einstein Audio Components remain the principle lines at Aaudio Imports. Recent additions of the extremely high-end turntables by Bergmann Audio and the only other plasma tweeter speaker company in the world, Lansche Audio, are just more blatant examples of the drive in which Brian is so hopelessly entrenched. Horn speaker aficionados are well served by Acapella’s speakers, from the $49,500-per-pair Violon MK-V to the $205,000-per-pair Triolon Excalibur MKII, each model being adorned by arguably the most exotic tweeter in the world. By the same token, readers seeking to spend less have the option to enjoy the refined Acapella horn with the $32,000-per-pair LaCampanella MKIII sans the ion tweeter, the first edition of which I reviewed to great satisfaction, while the connoisseurs among us will be most happy, proud, and envied by being the owner of the $455,000-per-pair Sphaeron Excalibur.

If you are as big an audio junkie as I am and will be happy just to have a pair of speakers with ion plasma tweeters, then I suggest the Lansche No. 3 at $25,000 the pair, or even the No. 5 at $35,000 per pair. Not as exotic as the Acapella horns, but exquisitely equipped with the only mass-less type of tweeter in the world. Of course, I feel the most sorry for myself, and decidedly less for everyone else claiming to be an audio junkie like me, for the fact that there is a pair of the Acapella High Violoncello II and Lansche Cubus to choose from, both priced at around $80,000 the pair and equipped with ion plasma tweeters albeit operating at different ranges. You mustn’t get on my last nerve by asking me what to do with $80,000 worth of audio budget. It will be most unkind and inhumane of you. But you know what I’d do if I had $160,000 to spend.

Retrospectively, besides the Ypsilon line of super high-end electronics and the Lindemann line of solid-state electronics, he, in 2010, also brought in the more affordable solid-state electronics line, Aaron, together with its higher-end sibling, Sovereign. In cables and accessories, the cable products of Stage III and accessory lines Audiotop and Weizhi complete the very select group of products under the Aaudio Imports umbrella.

Acapella Horns

Posted Wed Mar 10, 2010, 3:42 PM ET
By John Atkinson

As you will see from the forthcoming May issue of Stereophile, modern horn speakers don't suffer from the colorations and idiosyncrasies that plagued the genre in earlier decades. Such was the case in the room shared by Aaudio Imports and Sanibel, FL retailer Lee Island Audio. The German Acapella High Violoncello II speakers ($80,500/pair) with their ionic tweeters, driven by Einstein The Turntable's Choice phono preamp ($9,800), Einstein The Tube Mk.2 balanced line stage ($18,400), and a pair of Einstein The Final Cut tubed OTL monoblocks ($34,900/pair), connected with Stage III interconnects, speaker cables, and AC power cords, produced a seamless soundstage and a smoothly coherent tonal picture. With the LP of Rickie Lee Jones singing "Chuck E's in Love," played on a Galibier Stevio turntable ($15,000) fitted with a Triplanar Mk.VII tonearm and a Dynavector XV1s phono cartridge ($5250), the sound was one of the best I heard at Axpona. I have asked Aaudio Imports' Brian Ackerman for review samples of the Acapella speakers.

Dagogo/Richard Austen CES 2010 Show Report

Acapella/Einstein

Acapella was showing off their new High Violoncello II loudspeakers ($80,500) using mass-less plasma ion tweeters, with an Einstein front-end consisting of the “The Source" Tube CD player ($18,400), “The Tube MKII” preamp ($18,400) and “The Final Cut MK60” OTL tube mono amplifiers ($34,900 pair). Showing off is certainly what they were doing in this room. It’s tough to argue that there was anything better at CES and these were offering up a live sensation sound that very few rooms could muster. Due to the listening room’s two-level setup, I was advised to sit in the second level with the speakers at the other end of the room. I was happy to comply and was rewarded with considerably better sound. Large speakers need some distance and these were no different. The sound here was highly visceral with the thwack of drums and absolutely pristine top-end response – no hint of glare or other anomalies and huge impact without fatigue. It possessed wonderful inner resolution and decay and didn’t lose sight of overtones. Soundstage was large in all directions with solid, tuneful bass response. And they follow my demands that a speaker must play everything – classical to rock and do it well – these do both exceedingly well and will be happy with a wide array of amplifier choices. The jaw dropping price is justified by jaw dropping sound. Apparently this model is not even close to the top of the line.
