I have the DSJr fed by an Oppo BDP-105D through the coaxial input with a disc on repeat to burn the unit in. I am using a preamp (Bryston SP3) so have the volume set at 100. After a while, from a few seconds to a few minutes, the volume will drop directly to 60 with no input from the user, either volume knob on unit or remote. It hasn’t stayed at 100 for more than a few minutes since setting it up. I’ve turned it back to 100 with both the knob and the remote several times, and it’s not long before it drops to 60 again.
I have turned it off, cut power from the switch in back, and powered it back on after well over 20 seconds.
Thanks, Chris V.
