> I use iPad with RME ADI DAC-2 and I can't think of a single issue. I hope I missed a joke. That is a high end DAC that retails for $1300, and could very well be the best DAC available for less $1500. That'll do nicely. I'd prefer Lavry Engineering's discontinued DA11 (and AD11), but it's somewhat of a judgement call at that level.

There's nothing special in RME regarding its USB operation. iPad can emit material with different sampling rate (haven't verified different bit depth, but I guess, there should be no issues), iPad also knows not to meddle with the software mixing and delegates everything to the DAC. It behaves exactly as I'd like it to behave. No joke intended. My point was, that if iPad has no issues with this device, then it must be able to drive any other USB Audio Class interface.

    > Is there an example or anecdote you have in mind of a platform meddling with mixing? Sure, Android resamples everything to 48kHz, uses software mixing. No workaround. GNU/Linux by default does the same with PipeWire, PulseAudio and ALSA (dmix). One can configure it for bitperfect playback though. I can’t say about modern Windows, the last one I used was Windows 7, and by default it resampled everything to 48kHz too. > USB Audio that is special The last time I saw a non USB audio class device was some 15 years ago. I frankly do not understand, why are you stressing this so much.
