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 noticed that sometimes it's a light rheostat (sorry, dimmer switch) 

Any self respecting audiophile should get rid of all dimmer switches in the house.

Or, that self respecting audiophile could simply make sure all lights with dimmers are turned off while listening.

If this was my system, it would be rewired, use different outlets. If anything is 2 prong, instead of 3 prong, swap the cord around. On 2 prong power plug, swapping the plug around can have profound sound differences. 

Of course make sure there are no lights turned on, on that circuit, signal cables are away from power cables.

Might also be your amp needing some service, like bias adjusted, or a component going out of spec.
