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!

if it's a solid state amp it needs to be on all the time, I have a sim audio w8 and if I turn it off after 24 hours it needs to warm up for 3 days again before it sounds totally open again.

This thread is going EXACTLY the same way as the last one, and the one before that........    You say Tomato and I say Tomato.  You want to leave our equipment on, then leave it on.  You want to turn it off, then turn it off.  I doubt the argument has ever changed an opinion.  Time to move on to a new topic.  How about "do power cords make any difference?"  🤣 🤣 😭

@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 😂

If you have a tube preamp... turn it off because logic would tell you that you are putting time on the tubes.... Haven't seen any studies but it makes sense (I'm going to get 10 posts telling me I'm wrong). I've noticed that temperature and humidity makes the most difference in how my speakers sound even though those are only slight changes in my listening space.

There is what’s right practical and then there is what’s right to keep the the itsie bitsie brain worms from eating away at your pleasure center. My advice based on you OP is leave it on. Excessive heat is what kills electronics soooo. add cooling fans as needed to the hot parts as needed. Usb powered lap top coolers work great! Get a "Watt Power Meter Plug Home Electrical Usage Monitor" to see how much juice your amp uses over night (Less that $15 on amazon). This will kill that brain worm. Benefit will be you now will have an on/off switch that will last forever (a whole other topic of conjecture) .

Enjoy the music and as Van the Man says - "turn it up, little bit higher radio
Turn it up, that’s enough, so you know it’s got soul
Radio, radio turn it up, hmm La, la, la, la, la, la, la ...........
