Faint buzz in speakers

There is a very faint buzz coming from speakers with amp on, but with no music stream playing. Can only be heard with ear right up to drivers. No buzz with amp off or muted. Decent amp & cabling. Is this faint buzz likely still there under music when it’s playing? Numerous noise reduction devices deployed including dedicated circuit, robust grounding, balanced power transformer, various filters. Thoughts?

I recently had this issue with a new amp and it was my cabling picking up some noise. In my case the amp only accepts RCA connections, so this may not have been a problem with a balanced setup. Is it in one speaker or both, and if in both, is it the same level? Try turning off the amp, remove the interconnects, turn back on, is it still there?

Gold Note IS-1000MKII integrated amp. Does not fluctuate with volume. Ever so slightly louder (still very faint) in right speaker which is closer to amp. Have not tried removing all interconnects yet. Also, when all breakers in house except stereo circuit are off, same buzz still there.
