What Benefits Do You Really Get?

I'm always wondering and like to hear it from you guys. What benefits do you actually get by having your equipments ON 24/7? I do admit that my Power Amp sounded so MUCH better after 30 minutes or so, but other than that I'm hard pressed to find any other reasons. You will definitely shorten your Amp's lifeline (although some manufactures recommended that you always leave the power ON, why? because they do not want you to get stuck with just one Amp, the faster your Amp burned out, the quicker you're in the market for new one). Why not just turn on the Power for 30-40 minutes before listening? Have you guys heard of Manhole Explosions? if your car parked above one and if the explosion happened, your car is toasted.

One last thing guys, besides the high Electric bill to pay. After 10 hours or so, not just my Amp is hot but almost the entire room's temp is definitely raising. I think the class A amp will do that to anyone not just me as I am using a Pass X350, you know how hot that thing is.

When I first got my monoblocs, I left them on 24/7 because of what I read on Audiogon. After I got my first electric bill, I nearly had a cow, so no more 24/7 for me. It sounds good right from the start without any warmup. It possibly gets better after a few hours of warmup, but I really don't pay that much attention as to whether it sounds better with or without warmup.

Nguyen357, if your system sounds worse after a few drinks, you're drinking the wrong thing. Good cognac or 12 year old Scotch will do the trick. The older the Scotch or cognac the better.

Regarding MTTF in electronic systems, numerous factors come into play. Thermal cycling can have an effect, but it depends on what the low and high temps are, what kind of parts we're talking about and how much they're derated, etc. Leaving your gear on will wear down certain types faster (class A power amps come to mind) due to current flow and hence electrochemical migration. So depending on what kind of gear you have, how it's designed, and how you use it, turning it on/off vs leaving it on is truly component specific; making a blanket recommendation is not possible.

FWIW - I work as a reliability engineer in the semiconductor industry.
