My amps run at 100 watts each at idle which comes in at almost $12 a month. I definitely hear the sonic difference running them 24/7. I listen to music mostly over the weekends, so I power up my amps Thursday night.
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!
