I have a large Pass XP-30 preamp and I can't find a way to turn it off other than unplugging it, and I'm not climbing behind my equipment racks every night to do that. My McCormack UDP-1 doesn't seem to turn off either. I leave my Hovland Radia Amp on all the time because it doesn't sound good for many hours until warmed up and I listen every morning. I have a Moon 280D streamer which I do turn off. I'm not sure where the logic is there. My ARC PH-7 has tubes, so it's off until I use it. I had a McCormack amp and McCormack told me to leave it on, that it's power usage was like a lightbulb when not listening to music.
Leave it on?
I just listened to Paul McGowan explain that turning SS equipment on and off degrades the capacitors from the tiny power surge and that leaving SS equipment on ALL THE TIME is best. What do you do?
