If you don't hear a difference then there's no difference to you. I wouldn't care about others opinions if I were you. I've tried streamers from about $4500 and down and heard no difference. Buy a streamer based on features (do you need AES, USB, etc.?) and usability. Someone is going to tell you it's your USB cable or your system (not revealing enough has already been covered above). Ignore them and enjoy the money you save.
750$ Intel NUC vs $6000 Aurender N200: I don't hear the difference
I finally plunged into the source is as important as the DAC belief that is quite prevalent here and decided to test out Aurender N200. And given I have a very highend DAC, thought if the N200 pans out I would go for the N20 or N30.
I was expecting the N200 to blow away my Intel NUC which is 10th gen, core i7, 8GB and running Roon Rock BUT I am switching back and forth between USB playing the Roon Rock, and Co-axial playing Aurender N200, and I don't hear much of a difference maybe a hair, or not even that.
A few caveats: 1) Roon Rock is playing Quboz, N200 is playing Tidal (I am unable to get Qobuz login to the N200 for reason I don't understand).
2) I am comparing Coaxial on N200, USB on Roon Rock.
Caveat #2 can be ignored because I don't hear a difference between Coaxial and USB output of N200.
So either this is an "Emperor has no clothes" moment or I am missing something big. Any thoughts on what I might be missing before I send this N200 back to the dealer on Monday.
Rest of my system: Nagra TUBE DAC -> Accuphase E-650 -> Devore O96 and all Acoustic Revive wiring.
