SQ Comparison of 3 streamers

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. 

I was not using the terms interchangeably.  DSP is a different form of digital processing than up or oversampling or volume control.  but they are all examples of digital processing and so, by definition, they cannot be characterized as bit perfect.
