Have you listened in the morning before when the amp was off all night and had a different result? Personally, after being in a dead quiet room for 8 hours, my ears are much more sensitive in the morning then the night before. Even when I listen at night, or during the day, I try to have some quiet time before I listen. Relaxes me so I can better enjoy the music, but also gives my ears a rest.
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!
