Ahh, that makes more sense. I have only used the USB for copying files into the internal drive. Never tried using USB as an active drive on Aurender. I would still recommend you upgrading to an internal drive as I think this is what Aurender design was optimized for. Even if you still decide to move on to a different system I would guess having the internal drive would dramatically increase it’s saleability and though it is not perfect in all circumstances, the Aurender is a very good platform for playing locally stored music, Qobuz and Tidal. It crushes my optimized iMac Mini for sound quality and I expect you have to spend multiples more for dramatically better sound quality improvements.
Again, good luck
Again, good luck
