Audio performance steadily increases so far, I like it at least double as much as the first time plugged it in.
Started to play a bit with APO and a sound generator to get a flat response with my Headphones/Ears/Resonances,
and found there is some crosstalk between the channels.
So far I don´t know if my settings are somewhere off but checking aroung 4-9khz subjectively about "3%"
goes from one channel to the other. For example it means I can clearly hear everything playing on my left channel,
even though left channel is muted. Can someone confirm?
Also I´m normally a low-ohm guy, but probably will check something with higher ohms and good IEMs,
such stuff should be in my Box of Headphones somewhere.
Yeah, that's driving me nuts - I hope they can fix it with a firmware update. It happens when you go into the menu and change filters, too. You have to step it down and back up to get it at the right volume.
I think I´ve read something about that in the dac chips manual, to check what the roll offs do and such. When you switch the roll off and probably also on/off than that behavior is default of the dac chip itself.
Depends on Bursons way of accessing that chip, "Can you change Volume without physical interaction of the dac?", they maybe won´t be able to change that, maybe not even with an FW flash when that behavior is hardcoded,
or software if they are unable to send commands directly to dac. I´m using S/Pdif, if you have more options over USB like setting roll offs and such, let me know.
edit: I´m coming from an ZXR, which is known for very good channel separation. So maybe my expectation are to high?
You also could set Low/High gain and it saved that not as Asus does. They probably just didn´t want to fix their drivers. On the other hand when something is wrong with the driver, then ZXR defaults to high gain, which is not good either.
