James,
Thank you for your reply. I emailed a rely to your email to me, but here is additional info:
Purchased from Gasz Akustic in Rancho Cordova, CA, listed as authorized Bryston dealer. Serial No. 000596.
I connected the unit to my home network, no problem there. Attached an external HD with iTunes library on it and also plugged in the preloaded USB drive with hi-res music that came with unit. Downloaded MAX, again no problem. It recognizes both HD and flash drive, lists the songs, I hit Add All, pick a song, but when I press Play arrow, nothing happened. The song is not playing, stays at 0:00. Very puzzling.
