Seeking technician for in-home troublehsooting - dome tweeter hiss

Hello everyone,

I'm looking for recommendations on a SF/Bay Area technician or audio consultant who can help me troubleshoot a noise issue in my home system.

The amp is a Krell KSA-150 connected to a pair of B&W 804D speakers via AudioQuest Rocket33 cables. The system is powered through a Richard Gray 600s power conditioner. The noise is a high-pitched hiss coming from the dome tweeters, and is present even when the input source (Ayre Acoustics QB-9) is disconnected.

Any suggestions or recommendations greatly appreciated.

I would add that make certain the Krell is not plugged into the 600S,
for openers. All of your other gear is okay to plug into the 600S.
Keep me posted & Happy Listening!
