XACT S1. The music server you've been waiting for

JCAT WILL LAUNCH ITS OWN HIGH-END MUSIC SERVER AT AVS 2022 - XACT S1 – FEATURING WORLD’S 1ST 100% LINEAR POWERED MOTHERBOARD.

Designed from scratch, XACT S1, is a purist’s dream for those in the know. Based on JCAT’s 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 market lacked a genuine audiophile-grade motherboard. Most of the available streaming products are assembled using general-purpose PC motherboards. According to Marcin Ostapowicz, JPLAY & JCAT Founder, such motherboards with noisy switching converters all over the place should not be used in a high-end audio system.



XACT S1’s proprietary motherboard, apart from linear regulation, features extremely low-jitter OCXO clock with ±5 ppb frequency stability. 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.



Software is custom made and finetuned personally by JPLAY’s Founder, Marcin Ostapowicz, who promises superb sound quality and ease of use via included brand new JPLAY iOS app which combines Qobuz, Tidal and local content in a single beautiful interface.



According to Wojciech Pacu?a, chief editor of High Fidelity, the sound of XACT S1 is 'insanely difficult to distinguish from an analog source'. Come and hear it yourself.


When: 28-30th October


Where: Warsaw, Poland. Radisson Blu Sobieski Hotel, Room 718
 
Hi Ricky,

Which DAC are you using now? Do you have to restart the server or just a DAC?
Have you tried a different USB cable to your DAC?

Best regards,
Marcin
Hi Marcin,
I am now using the build in DAC in my Vinnie Rossi L2i amp. Before this I had NUC running Euphony playing in to the Meitner DAC with a different cable so I changed everything accept the Etherregen.
Both systems showed the same problem, short burst of noise and it stops the music. If you hit play again the song time elapses but no sound. I only have to restart the server. Not sure but I think not that it doesn’t work if I only restart the DAC, I will try again tonight.
Have you or somebody never had this?
 
Please try reconnecting/restarting the DAC. I don't think that restarting the server is needed.

Does it happen with all 24-bit files or only some specific format?

Tick/pops can happen with some DACs on sample-rate / format change. This is most common when switching to DSD though. But it should not 'freeze' the DAC which seems to happens in your system.

Best regards,
Marcin
