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?
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. |
I had a buzz or ground hum years ago, and after trouble shooting with the dealer ended up installing some gadget between ac cord and wall outlet that fixed it. It was called 'Magic' something. A search found this: https://ifi-audio.com/products/gnd-defender/ More than a 'cheater' but still retains safety of grounding. |
