Leave it on?

I have a Butler TDB2250 power amp. When I sent it in for some repairs I talked to B.K. Butler the owner and designer. He told me that leaving the power on was just fine. My amp doesn't have a standby mode. If it did I would use it.

Obviously my last post is irrelevant if equipment is plugged in and left on forever, but as you say, having more user options are plus points.

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. 

Like many, I leave ss gear on 24/7, unless i'm going out of town for some time. Tubed gear gets turned on for listening, then off at the end of the evening.

The only exception to this is the Aleph 2's I own. Those generate so much heat in my small listening room they get treated like tubed gear.

@audiodwebe Yep I turn my Aleph 1.2's off nightly after listening – the heat but also the electrical bill.
