It is, as many stated, amp specific. I will add that it is also user specific. In my case the weekends are my music time, so my system is off all week. When I get home Friday night, I turn everything on and leave it until my weekend is over. My Macintosh gear always sounds better by Sunday. Could be the bourbon helps some. I am going to do more studies. Wish me luck.
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!
