solid state gear- leave on?

Maybe a more honest answer is that neither the heat from leaving it on all the time nor the effects of cycling it on and off are likely to have a significant effect on the longevity of SS gear. As to its impact on sound quality, speculate away.

To Tireguy: You confuse cycles and trends (and ignore the bulk of inconvenient evidence). But your attitude doesn't surprise me.

I too am forced to respectfully disagree with Pabelson. Turning an SS amp on and off daily is -the- action that shortens its life more than anything else (given the presence of adequate ventilation, of course).

Also in response to Pabelson, SS amps pull differing amounts of current depending on their design. Many pull very, very little, especially when idle. While I agree with you about our obligation to confront global warming and the dependence on Middle Eastern oil, I don't think it should be made into an issue here.

My last ss amp was never left on; it lasted 20 years. I finally got tired of it and sold it and it was still working when I sold it. Maybe I was just lucky. Hope all is well.

I tried running my amp 24/7 on cow farts. Sounded great, but the damn cow took up most of my listening room. Smelled pretty vile too. I'm going back to the more simple weasel dung conversion system (WDCS™ patent pending). Much easier to live with. Butt steak anyone?
