Amp — Leave on or turn off


I always turned my Benchmark AHB2 amp off after use every night. After all, why is there an on off switch on the front panel if not to do that? Last night I accidentally left it on. This morning, when I played my first record, I couldn’t believe my ears. The same record I played last night sounded infinitely better. I tried a second record and that, too, was much better.
I know there’s a debate on the question of leaving an amp on all the time.
I now know where I stand!

@rvpiano you can leave all your benchmark components on. Extreme heat is the enemy of electronics. The SMPS doesn’t draw much from the wall and there’s no energy to convert to heat. So you’re safe to leave it on if it sounds best to you that way. No harm.
With my Pass X260.8 mono amps that are Class A biased for the first 35 watts, I put them into standby when I’m done listening. They take couple of hours to come to temperature and sound their best which is ok to me. The space heating is an added benefit in the winter 😂

I don’t have solar panels. Does this mean I can resume playing Peel Me a Grape that I had on repeat for close to 30 years in my high power consuming system? Cause I just paused it for few minutes to check if I kept that coal plant alive all this time….no bueno there…the last of the mohicans in NJ it was demolished few years ago. 

There are close to 220 operational coal power plants in the US. China has over 3,000.
Our contribution to pollution by leaving our amplifiers on can’t even be measured. I’m not saying we don’t need to be conscious about it, but the environmentalists on this thread…you guys are barking up a wrong tree.
Alright enough politics…hate this in the audio forum. There are other places where this can be debated.

@bigtwin lol

great thread by @rvpiano as always.

look…no matter our political beliefs, we share passion for this hobby. But some make repeated attempts to bring devision even into these pages.
