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!

I had a Krell FPB 600 amp that I always left in the standby mode until I powered it up to listen. Was doing that for years and years. Then I have now the ARC Ref 750s. And I always let them warm up about 1 hour before listening. Happy listening.

Class D / on 24/7

Class A / off

RVPiano - are you aware the Benchmark can be set for auto shutdown 

after 45 minutes of sensing no audio signal? Also the Benchmark handbook 

states that due to the SMPS power supply the amp is at its full potential the moment it is turned on.

Both my Hegel H390 and my PS Audio gear all stay in standby mode until I wake them up. Both take less than an hour to sound great.

@kckrs In my experience, Class A/AB also on 24/7 unless traveling. We really should follow the mfr recommendations. And if you bought used, the manual is available online.
