Slight buzzing sound

So I’ve never actually tested buzzing from my speakers with no music playing until tonight. With NAD M51 turned all the way up I have to put my ear to the left speaker and I hear an audible bzzz. However at the same time the right speaker has zero bzzz….

I dunno if this has anything at all to do with the quality of sound but I found it odd that the left speaker has this slight bzzz maxed out volume, but the right ch. doesn’t at all.

And this buzzing sound is w/my ear right in front of the speakers. I can not hear it from listening position enjoying music.

Does this mean the left channel on the amp is “going”?

    Swap the L and R inputs to your amp and see if the buzz switches channels. If it does, it’s coming further up stream (pre or source). If it stays in the L channel, swap the speaker cables L and R. If the buzz moves to the R channel, it is in fact the amp. If it stays in the L speaker, then it’s something I. The speaker (crossover probably). Obviously make sure everything is powered down when making the cable swaps.

    Also make sure you don’t have cables touching each other. You could be picking up RFI/EMI; doesn’t necessarily happen in both channels the same way.
