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.

snapoli, thanks. I've came to the same conclusion, although certainly nothing that I can prove. Mine's quiet enough that I can't hear it from a couple feet away, and certainly not when there's music playing. It still peeves me, because it's a recent thing with it.
Appreciate everyone's input, thanks.

My dealer and Luxman said that. My dealer emailed them and the chief engineer said because they are class A they buzz when in idle.

No buzz with my L-590AXII. Something is wrong with the unit or the mains power supply if there's a buzzing sound from the amp.
