    Denafrips Sub-Brand or Rip-off? The case of Musician Audio's Pegasus R2R DAC

    It's fully obvious looking at the pictures that Musician and Denafrips came out from the same factory, this is probably the only data point we can warranty. So my opinion after reading Srajan and others: Denafrips/Musican are run by the same people. Why?. No idea, but per Occam's razor is the...

    Gustard U16 - the first USB Interface featuring ESS USB chip

    That's pretty awful. The highest I use is 24/96 which is the limit of the Genelec One's AES.

    Gustard U16 - the first USB Interface featuring ESS USB chip

    Why?. I've been using the U16 to feed my Genelecs with AES during roughly one year and is rock solid. Not a single glitch, issue. I use it from a Sony laptop in windows.

    Gustard X26 Dual ES9038PRO DAC with ESS USB chip

    the Chord Qutest and RME ami-2 are reported to be very good. In addition, it has to outperform $5k DACs to be good?.

    Gustard X26 Dual ES9038PRO DAC with ESS USB chip

    well, at least it means the unit is not broken, which is more than nothing ;-).

    Gustard X26 Dual ES9038PRO DAC with ESS USB chip

    Guys, independent measurements of the X26 shows that it's an stellar DAC from the technical point of view. It is so good that even the ugly Sabre IMD hump does not exist. https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-gustard-dac-x26.7007/ how it sounds...

    Gustard U16 - the first USB Interface featuring ESS USB chip

    Funny, I was looking for a DAC, and found that RME realsed recently the RME ADI-2 FS, a stripped down version of the Pro version at half price. It has not USB input, it's obviously geared towards professionals, and more likely the DAC section is the same in both. Now with the U16 I'm...

    Gustard U16 - the first USB Interface featuring ESS USB chip

    you're right!. I didn't have the wasapi installed. I installed it and now the display shows the correct frequency. That was silly on my side. Thanks!

    Gustard X26 Dual ES9038PRO DAC with ESS USB chip

    I bought a Gustard U16 interface, and the construciton is very good. This DAC looks very well made as well. But in same price range we have the RME ADI-2 DAC which has solid measurements behind, and this X26 must have something to offset the risk of purchasing from HK with respect to Europe/US.

    Gustard U16 - the first USB Interface featuring ESS USB chip

    Doing the first tests with my U16, but the screen only shows 48khz, irrespective of the sampling rate in foobar. That's happening in a laptop with Windows 8 and another with Windows 10.

    Gustard U16 - the first USB Interface featuring ESS USB chip

    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...

    Gustard U16 - the first USB Interface featuring ESS USB chip

    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...

    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.

    well, take $285 as a base price. I can't believe you guys won't mod ;-).

    Gustard U16 - the first USB Interface featuring ESS USB chip

    @Whitigir, glad to see you are so happy, that's the goal of this hobby :-). I agree with you about the price, nothing ridiculous. It looks solid engineering giving a real upgrade at a decent price.

    Gustard U16 - the first USB Interface featuring ESS USB chip

    @RAFA: Those clocks only synchronise internal clocks, which are still important. This is something I don't get. External World Clock do not remove the internal clocks?. Internal clocks get slaved to the external master clocks. Low frequency phase noise should be strongly reduced. Or they...

    Gustard U16 - the first USB Interface featuring ESS USB chip

    What's your SU-1 mod?. Clocks, PSU?. The U16 can also be modded: better PSU for sure, and probably an external clock (cybershaft ??) because its clocks are not fantastic. We have to wait and hear to compare with the SU-6. However, the SU-6 will be much more expensive than the U16.

    Gustard U16 - the first USB Interface featuring ESS USB chip

    The only thing refraining me to get the U16 is that I want to wait to see how new sinxger SU-6 performs. Anyone using AES?. If so, what cable do you recommend?. I have a pair of XLR built by myself with oyaide plugs and silver occ cables, but I'm sure the impedance is not 110 Ohms.

    Abbingdon Music Research DP-777 Thread

    I'm having my second issue with this DAC since I bought it near three years ago.   The first one was the USB card that stopped working some months after purchase. However, the service of AMR was pretty good and they sent me a new usb board user repleacable that fixed the problem.   Now the...

    The Stax Thread III

    Hi,    I've a 2nd hand SRM 727A to run a new SR-007A. I bought a very nice neotech AG/AU wires and  some good XLR oyaide connectos to do my own XLR interconnector from DAC to SRM 727A.  But before of that..    Do I build a regular pair of XLR intereconnectos to run the 727A, or do I solder...

    XLR interconnector to the Stax SRM 727A.

    Hi all,    a question to experienced stax users. I've a 2nd hand SRM 727A to run a new SR-007A. I bought a very nice neotech AG/AU wires and  some good XLR oyaide connectos to do my own XLR interconnector from DAC to SRM 727A.  Now that I got  a mundorf supreme solder I'm ready for the fun...

    Stax 727 Voltage Conversion 100 to 117 (Help)

      haha is true, they have cut the wires and put glue in the holes, they are mean at Stax!   I'm leaning now towards a less ambitious mod, and just solder the XLR cables as close  as possible to the board. I don't know if that will make a difference, but I bought some fancy OCC silver/gold...
