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.

So the OP has the mk1 version of the L-509X. Just to clarify that my L-590AXII does not show any hum. Very silent and no issues whatsoever except that it automatically shuts down by itself, occasionally, after prolonged listening sessions at moderate to high volume levels. Guess the protection circuit feature of the amp is working fine which is a good thing!

Nothing here is about the L-509X, which is an entirely different piece.
I own the L-590AX. There's no version that was ever called a MkI, throwing weird names in the mix won't help clarify anything.
On a side note, I'm inclined to think that your amp shutting down is indicative of a problem that needs addressed. Do you have plenty of room around the amp? They need to have good ventilation.

Yes, plenty of space around the amp. It only happened twice for the past 6 months of use.

All I can say is I love the sound of the 507ux and the complete lack of buzzing. :)
