In the same light I had an Innous player come in for an audition. It was played through USB. My normal player is an Intel nuc i3 with 8gb ram, using Audirvana 3.5 and out a Matrix USB card all attached to a LPS.
The Innous was bested by a bit but both were fairly close.
Later I brought in a Bryston BDP-3 player and went through the same audition. This time the Bryston player won out. But again the difference was minimal. As a side note, the software although seemingly old school, is extremely quick, and bug free.
I would now like to bring in an Aurender to try again, but I think due to their software issues I read about online, I really don't want to deal with those problems.
p.s. Introducing Roon never helps the sound quality, and it is why I will never buy it even though the interface seems to be second to none.
