    I would love to measure it. But it is cheap enough that if I see it at CES, I could try to buy one. If I fail, and you like to see it measured, I would be game.

    The Gustard X20U is popular in Mainland China. There are some owners in Hong Kong too.

    The HK dealer has designed a femto clock (Crystek 957) add-on board with better psu boards for it too :

    That's excellent! The exact clock I recommended Marty to upgrade his with. That would make a big difference and most likely take it into the league of DAC's in the $5000-$7000 USD range!

    It would sound better with non magnetic hardware used to hold the trannies down....and of course, an audiophile fuse. Looks like it uses op amps for I-V conversion then discrete after that. Would sound way better with one discrete I-V stage and coupling cap straight out on each phase (no summing for unbalanced outs). WAY BETTER! Mike knows what op amps sound like....this has one and then discrete stages ......one discrete stage only would be killer! The better clocks and power supply are cool too.

    No doubt!

    Conjecture, for sure. Even if it is a hybrid from Dustin does not mean a pure simple discrete would not be better. You have to listen to know anything. As long as the signal goes through an op amp....it is colored by it (in my experience). Of course, I am always open to learning something new. If a hybrid circuit could beat a single discrete stage I am all for it.

    Actually, I have found a simple j-fet buffer on the output of the ESS DACs sounds best. Just one super wide bandwidth zero feedback device biased into class A with another j-fet. Mega ohm input impedance and 50 ohm output impedance.....then a coupling cap. The only downside is that you only get one volt per phase.
