The hum issue seems to be fairly common with Luxman integrateds. I have a 507ux and it also started humming a few years after I bought it. The amp itself is dead quiet-no sound from the speakers-just from the unit itself.This issue has come up a few times online. Some people say you need to tighten or put insulation under the transformers. I have been meaning to write to Luxman about it but haven't gotten around to it since it is doesn't affect my actual listening experience. Very disappointing though!The new Luxman distributor seems like a much more helpful guy than the previous one. Hopefully they will offer some suggestions that don't involve Bulgarians.
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.

Reports of Luxmans with hums go back at least five years, probably further. https://forum.audiogon.com/discussions/luxman-class-a-integrated-slight-buzzing-noise/post?highlight=luxman%2Bhum&postid=78228#78228 |
Interesting thread. Have never heard of this issue with reference to the current version L590axii, but since that amp is on my radar I’d like to know in advance if that model is also susceptible. Anyone know if Luxman corrected the issue with release of the L590axii, or does the hum issue arise there as well? |
