Digital that doesn’t sound like digital. More like vinyl. Or a private concert.
"XACT S1 delivers on my vision of audiophile sound: natural, organic with analog sophistication and lifelike imaging. It’s hard to believe it’s digital."
Now available in the “EVO” model for even higher sound quality.
 
Master OCXO Clock
The Master OCXO Clock in the XACT S1 EVO represents a significant upgrade in digital audio performance, drawing on advanced clock technology similar to that found in high-end audio clocking systems. This clock module is entirely developed in-house, emphasizing precision and stability, which are critical for achieving exceptional sound quality. The result is a digital audio playback that captures every nuance with remarkable clarity.
 
PHANTOM™ Music Drive Cable
By utilizing the same cutting-edge materials and precision construction techniques as our new PHANTOM™ USB and LAN cables, the PHANTOM™ Music Drive Cable minimizes signal interference and preserves the purity of the audio signal. This results in a listening experience that is not only more detailed and lifelike but also imbued with a richness and depth that brings music to life in the most natural and engaging way possible.
 
IMMOTUS™ mechanical isolation.
 IMMOTUS™ ceramic-aluminum isolation footers, introduced in the XACT S1 EVO are the culmination of years of research and a deep passion for enhancing sound quality.
Internal vibrations generated by audio components can be  more detrimental to sound quality than external ones. Standard feet made of soft damping materials often fail to address this issue. This understanding led us to develop IMMOTUS™ footers, designed to effectively channel these vibrations away.
 
Designed and developed from square one. Fine-tuned by ear. Obsessively.
 
Not another PC. A completely new device.
Most streaming products available today are made with standard, ready-to-use mini-PC motherboards designed for office or home entertainment. However, these motherboards have noisy power converters that interfere with other hi-fi components and produce an irritating “digital” sound. Some companies try to mitigate the issue by upgrading their power supplies, but this doesn’t address the root cause. That’s why developing an entirely new motherboard from scratch with only audio playback in mind was the only way to go with XACT S1.
 
100% linear power delivery.  Truly everywhere.
It’s the first music server that puts so much emphasis on power quality ever. The motherboard itself has only linear regulators and runs solely on linear power. The dedicated power source is 100% linear without any switching components. XACT S1 delivers unmatched electrical performance. There’s nothing else like it.
 
XACT OS written from scratch and optimized for the hardware.
 
One app to rule them all.
Effortless management and discovery with JPLAY™ app.
 
Only the finest components.  Obsessive attention to details.
Every component in XACT S1 EVO is hand-picked or developed from the ground up and thoroughly tested by ear. No other company has gone to such lengths in music server design.
