We have to define our problem before we can come up with a solution. (It's an engineering thing)
Problem: There is no external soundcard/DAC that has low levels of jitter combined with high voltage multi-channel outputs (more than 2), that does not run on 110V AC in a small package, and has interchangeable parts such as opamps/caps/DAC's for customizing the sound.
I think that sums it up for everyone listening. Correct?
Aparently I wasn't all that knowledgeable about usb audio
If the software that is going to be used can support output to multiple audio devices, you could just use 4-5 stereo dac's on one PCB, with one PSU and a USB hub to only use one USB connection (if bandwidth allows for this, but I guess it should).
That way your computer will recognize 5-6 devices (dac's +hub) but you can use them the way you want!
Even using some outputs for different audio output/multi zone (wireless headphones?)...no problem as the computer sees the different channel pairs as different devices!
Just my 2 cts
Damn..... Should've had a look at this thread from the beginning.... Interesting! And if the DAC gets built, you can be sure I'll take one.... Hell, now I'm gonna read the whole thread
