XACT S1 

State-of-the-Art Digital Transport and Music Server:

Featuring Worlds First Linear Powered Motherboard
for high-end audio playback.

JCAT introduces flagship series XACT which demonstrates the very best that can be achieved in digital audio playback. The S1 music server is a statement product that delivers unmatched performance.

ZeNA (Zero-Noise-Architecture)
Designed from scratch and fine-tuned solely for high-end audio playback, XACT S1 is a purist’s dream for those in the know. Featuring JCAT’s proprietary ZeNA (Zero-Noise-Architecture) motherboard, the S1 does not rely on switching DC-DC converters. Instead, super-low-noise linear regulators are used exclusively making XACT S1 the world’s first music server running on linear power alone.

The only Music Server on the market featuring motherboard designed exclusively for high-end audio playback.
The market lacked a genuine audiophile-grade motherboard. Most of the available streaming products are assembled using general-purpose PC motherboards designed for office work and gaming. Such motherboards with noisy switching converters should not be used in a high-end audio system as they pollute other hi-fi components and contribute to irritating 'digital' sound. Some companies try to improve their PC-based music servers by using better power supplies, which is a good practice, but eventually the final result is compromised by generic motherboard not suited for high-end audio playback.

The Finest Audio Components.
XACT S1’s proprietary audiophile-grade motherboard, apart from 100% linear regulation, features extremely low-jitter OCXO clock with ±5 ppb frequency stability - the same that is used in JCAT's XE cards. The extensive power supply section based on JCAT’s renowned OPTIMO linear PSU delivers 140,000 uF of capacitance provided by Nichicon’s flagship Muse and Fine Gold capacitors series, ideally suited for first class audio equipment. Internal SSD selected for its sound properties offers 4TB of storage and is connected to the motherboard via Reference SATA cable to ensure absolute best sound quality. Up to 16TB of storage can be added as option.
