Here's another tidbit of audio nervosa; never mover tube gear warm, it must be totally cooled down first. To do otherwise is to invite the tubes to become microphonic!
Tube microphonics
Hello. I am using Audio Research Ref 750 mono blocks and they in front of my speakers but off to the sides. Someone told me on another site that if I move the amps beside the speakers and not in front of them , my system will improve immensely. It will reduce tube microphonics. What are your opinions of this and I just want to say that I’m very new to tube amps so this is something I never heard of before. Thank you all.
