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 had the same insidious problem. It was caused by the ground plug. Even though it is NOT recommended to use, I simply installed a ground plug adapter and eliminated the ground prong. It worked. Buzz was finally gone!

It was the ground plug on my pre-amp that did it.

Be aware you are eliminating an important safety feature when you do this.
