SQ Comparison of 3 streamers

@OP: Innuos Zen MK3 owner here. It's very nice! I have also tried at home, at length, an Innuos Pulse and an Innuos Zenith MK3 and both of these have better technicalities but not quite as great musicality and not quite as natural timbres as the Zen. 

one more follow up: am not a Qobuz Connect user but it’s marketed as bit perfect, and I think I saw a youtuber who proved that it is bit perfect thru a side by side digital file transfer, fwiw.

Right now I’m running everything through a tube pre known for its clinical character and into a Buckeye Hypex. It will be interesting to compare again once I connect an Orchard Audio Starkrimson as while I believe it’s still Hypex based the implementation with more caps lends itself to a warmer more lush and musical presentation.

My amplifier modules are completely my own proprietary design. Starkrimson is the name of the technology, and I also hold the Starkrimson trademark. Read more on that here:

and we know Volumio is bit perfect, so that’s why the OP’s experience is so interesting to me.

@mdalton I did not mean dsp in a sense of up or over sampling . I meant the processing path that the data stream takes before it is output to your streamer. Sorry for the confusion. 
And yes device settings matter for your streamer and or dac.
