Yes, I’ve got the integrated and, yes, I’ve got the low hum. Not really that noticeable. I wondered if it was a characteristic of a Class A amp since I’ve never had one before. It runs very hot.
question for Luxman L-590AX owners
I own the subject amp, have had it for 3-4 years. I recently noticed a low hum or buzz coming from the amp itself (not the speakers), and would swear that it has been dead quiet up until now. You have to have your head right down beside it to hear it. I'd like to hear what other owners have to say. Are your amps completely quiet? Seems like I may have developed an issue. Thanks in advance, and Merry Christmas.
