USB and Coaxial at the same time?

I used both coaxial and USB at the same time to test the sound of each on my Aurender N200. I called Aurender and they said it was not designed to use both cables in the unit at the same time. The difference was very slight. NowI only have coaxial connected.

@rvpiano interesting that you prefer coax. Thought you liked that shunyata usb cable

@audphile1 

i thought so too until I compared it to the coaxial.  It cut out the highs.

@erik_squires

USB of course is the only choice for very high resolution formats and DSD

You are really ruling out HDMI?  Really?

@rvpiano USB cut out the highs? That’s strange. I only had DH Labs coax and I actually got more vibrant sound from USB. Even stock USB cable sounded more open. Could be that Shunyata cable no bueno.
