A class D amp takes 24 to 48 hours to properly charge the caps and settle in since it is 95% efficient. You don’t want to EVER TURN ONE OFF SO HELP YOU GOD unless you are plugging in things into it
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!
