I have been having problems with my SP2 pro. on and off for a while now. I recently installed new firmware received from Mike at Bryston (May 2, 2008, version) everything installed properly and thought that would fix things, but I'm still having the same problems of the unit shutting down then restarting again with the volume going all the way up or the volume staying down with the volume motor staying on.
I never seem to have the problem in 2 ch bypass just when I switch to a digital input.
The only thing I have added to my system recently is a 46" plasma with digital out into the pre-amp.
(replaced a 27" CRT with analog out), and it still happens with the TV off.
Any suggestions or do I have to get the box down from the attic.
