You are not a sound quality evaluation device
It is a dac and adc (very respectable performnace) with built in dirac correction and licence. It has 4 channels and can do 2.2. It also has a built in streamer which will run volumio natively and squeezelite with a tiny bit of faffing* via wifi or ethernet.Can you say a bit more about the minidsp shd?

I find it very neat as a preamp dac , dirac device and streamer. Aside from playing music from my nas under the stairs via wifi it also takes an anlogue input from my turntable> phono preamp.
There is also a version with no analogue outputs so you can use the dac of your choice.
Of course there are plenty of other solutions, but it's pretty neat and well engineered. It's about £1500 in the UK though.
*unfortunately the version of squeezelite which comes with minidsp's own version of volumio doesn't work, but there is an informal work around via ssh, and it's irrelevant if you use volumio itself, or just connect your pi via usb or s/pdif.
