Well I'm getting used to the menu and enjoying the various streaming options.
I did get the infamous "Can't play track" on a few albums. I powered down the server from the menu (not the power button) and powered back up and it persists. I hope the files are good. Not sure how to resolve this one.
I'm shocked at how good the SU sounds with the Cardas speaker wire, I expected it to not be very palatable.
