It can handle DSD128 but 256 is where it all falls apart. The Gustard locks on to the 256 and 512 signal but listenable sound just isn't there. I'm seriously thinking it's the I2S lines since the audiophonics provided jumper cables are about 8" long and the cards, for now, are sitting directly below a monitor. Tomorrow I get my solder wick and new tips for my Aoyue 937+ which, at 45 watts IIRC, should be able to handle quick desoldering so I can remove the pin header from the DIYinHK board, break it into the right size, and directly solder the audiophonics card to it, eliminating the weak link. From my reading, LVDS signals are fairly robust in comparison to the pure I2S from the card. That should also allow me to break/make a header tor the DIYinHK screen so I can watch the VU needles go crazy and see what signal the card is outputting.
I also spoke with audiophonics about power draw (I don't have a .1-ohm resistor handy to measure across) and apparently the power draw is around 1A on the 5V line. That board is seriously thermally efficient. Unfortunately, that also eliminates the possibility of paralleling the power supply rails for thermal management. Perhaps it's time to make a benchtop supply out of an old ATX psu.
