Do you leave your components on 24/7?


Lately I've been leaving my components on all the time, on the assumption that a) they'll be ready when I want to listen, and b) the on/off cycle ages the equipment (tubes, anyway) faster than leaving everything on. Is the latter a reasonable assumption?

Many of you are so ecologically bad; it's beyond words. You can buy electricity but you won't need it in hell. Keep it on all the time.
I think hell would have to have electricity...what...it runs on some imaginary power? Get real....
I don't think Hi Fi's are allowed in hell . A good reason not to go . Besides music there would make it more like heaven .
As far as being ecologically bad , the higher brake down rate caused by thermal switching would have other ecological affects that may be more consequential than the extra power used .
I wonder what this "breakdown rate" might actually be? I've been an audio fan and pro musician/soundman since 1967 and I personally haven't experienced much breakdown at all...and the perception of things sounding better after sometimes hundreds of hours of warmup seems more like a design flaw than otherwise, although since it's a fact of life among respected gear reviewers who hear much more stuff than I even will, I will allow it. "Mister nice guy!" My gear goes on as background music when I read my morning paper, and often stays on all day...maybe it's warming up and I didn't know it, but I haven't noticed much, if any, difference.
