Gustard U16 - the first USB Interface featuring ESS USB chip

[Chopin75]

I will, but not anytime soon, since the pins are not compatible.

XMOS is a General USB chip though, where this ESS is dedicatedly made for Audio purposes

So one needs to change the pin config, hope it won’t be too hard

what cables are you using for the gustard?. I own an old acoustic revive USB and some DIY interconnects with with pure silver 24 gauge, and I don't know if it makes any sense to spend more into interconnects.

I use as with SU-1 so AQ Carbon USB & HDMI.

I don't know whether this would have any benefit, but it is possible an electric isolation PC -> DAC using fiber and later converting to USB, with something like the ClearFog Base https://www.solidrun.com/product/SRM6828S00D01GE008B00CE

The usb from the ClearFog Base could be plug into the Gustard U16?. A complicated way to get electric isolation, and might be even worse than a simple jitter-prone toslink, but who knows.

Fiber meaning optic fiber?

 

[Cortes]

yes, optic fiber. The idea is to change from electric propapation of the signal to light propagation in some part of the signal path to completely block electric issues. This separatation is definitive, something like the usb galvanic isolators but taken to the highest level.

I just checked on amazon, and there is a full range by Startech of usb-> optic fiber converters

So, leaving gremmlings aside, after the optic fiber the usb signal should be with no electric noise, apart from the own SFP->USB converter, and simply a good usb reclocker/clock should provide an ultraclean signal.

Latest firmware update 1.4:

V1.4 firmware update diary:

1. Optimized the logic of NATVIE DSD playback;
   
   
2. Optimized the compatibility of S/PDIF DOP output, and solved the problem that some decoders can not correctly recognize DOP signals when connecting coaxial or AES;
   
   
3. Solved the problem that running STEAM program may cause NATIVE DSD to be silent;
   
   
4. Fixed the phenomenon that the level meter will be full when the professional decoder is connected without playing music.
   
   
5. Fixed the stability under the MAC system;
   
   
6. Added WCK word clock hold function in PCM sampling state, can continue to output WCK word clock signal without playing music state;
   
   
7. Added the audio signal hold output function in the PCM sampling state, and can continue to output the audio signal without playing music

Great to see they keep hand on the pulse.

Is that using USB to ethernet or vice versa? I don't see any fiber optic outpt. Or the conversion to optic is done momentarily inside the device ? There are USB and HDMI made with optical fibers which you can also use for galvanic isolation. There is supposedly some PCle card with toslink ouptput but I can 't find them.
U need a really nice toslink, not cheap plastic to prevent jitter

Yeah, software is just as important as hardware. I am glad they are working on it

Did anyone compare U16 against singxer su1?

Seems, this is for PS Audio I2S standard:

[PitBul34]

Firmware v.1.4 PS Audio - works pretty good and problemless with Denafrips DAC-8PRO2.

Much much better than Singxer SU-1 !
