Leave it on or turn it off?


I have a Classe CA-301 amp. When I leave it on 24/7 it gets very very hot(SPACE HEATER). If I only turn it on when I'm listening to music it stays quite a bit cooler. What are the long term advantages to just leaving it on?(If any) Thanks in advance.

The energy vs. sound quality is a real issue. I leave my whole system on 24/7, before I get jumped on I should say my Aloia amps use 35 watts each, my Aloia pre-amp 25 watts and my Sony SCD-1 30 watts, thus a total of 125 watts. I feel ok with that level of waste in that I choose not to drive an SUV but an old Mazda 626. Everyone will make their own chooses, but most people I know live in glass houses so I hope not to hear from them. For those who want 600 watt pure class A or big tube amps, then that is an issue too, the power consumption for one disk is equal to my week of 24/7. I think the manufacturers could start looking at new designs that provide quality and are environmentally friendly. KRELL, BAT, C.J., Classe ... are you listening?
I have a pair of Bryston 4B ST amps. Should I leave them on 7/24 or not?

I leave my Classe CA200 on all the time. I do feel a little guilty about the waste of electricity. Does anyone know how to figure out how much electricity my amp uses in idle?
Jsbail,
You need to get an amp meter hooked up to the hot wire on that particular circuit. I am an electrician and am thinking about running that test myself. I will report the results and post the formula for calculating power consumption if I can get around to it this weekend. Does your Classe manual say 300 hrs warm up time?
Thanks Glen, My Classe manual makes no mention of warm up or break-in time. I will look for your test results. Jon
