Current fave cheap DAC HAT for Raspberry Pi?
I'm trying that now (listening through DAC outputs to O2 headphone amp and Sony MDR-7506 headphones). Switched from 32bit/384kHz, High Quality to 32bit/352.8kHz, High Quality. There's very little, if any difference. But...

I have a recording with a very loud cymbal crash at one point (Joe Henderson, "Miles Ahead" from "So Near, So Far'). I couldn't swear to it, but I think that cymbal crash sounds ever-so-slightly less hissy and more like a cymbal with the oversampling set at 352.8kHz rather than 384kHz. The difference is tiny, but I think I can hear it (more like feel it).

Then again, if you gave me a double-blind test and asked me to guess which was which, I bet I'd come out being right only half the time, at best.

Half an hour later, I think I can reliably notice a difference. I like 16/44.1k upsampled to 32/352.8k better than 32/384k. The difference is barely noticeable.

Wow. Lots of great discussion (and the usual 'volatility') here, though some of it is way above my pay grade.

Just asking - no 'love' for the HiFiBerry boards? I've been running a DAC+Pro XLR and have been very happy, but have nothing to compare it to.

Just curious, how would one use these as a DAC for CD transport without a coaxial or optical input? Is there a DAC hat with these inputs, or a coaxial/optical to usb adapter?

You would likely find yourself using a USB soundcard with a digital (SPDIF) input. The cheap(est) is based around CM6206LX and costs about $10. You would become quite familiar with the Linux "amixer, alsamixer" commands and possibly ".asoundrc and asound.conf".
