Bill_k is correct. There's nothing wrong with your amp. My Rowland does the same thing, as do many other amps.
Woofer thump when preamp comes out of standby
Hello all, just recently purchased a Belles 350a power amplifier here on audiogon. Placed it in my system and now I have thumping woofers as soon as my preamp comes out of standby to ready mode. The preamp is a conrad Johnson PV-7. The Belles replaced a pair of Cary SLM -70 monoblock tube amps. I had never had this problem with them. Any ideas what might be causing this problem? Would a dedicated 20 amp line to the power amp solve the problem or is this more of a ground loop problem? Also wondering if the preamp is inverting and the amp isn't, could that be the culprit? Any help would be greatly appreciated.
Thank you!
Thank you!
