LED dimmable lights in audio room?

Mine too, @oregonpapa .

Didn't know if the new LED dimmable lights (and dimmers) still had that problem or not. :(

They'd be on a separate circuit. I don't know any audiophile electricians, unfortunately.

Hopefully someone has done this and has some advice on how to proceed.

Yes, there is always a potential for problems, with both dimmers and LED lighting.  A local dealer had to troubleshoot excessive noise in a customer's system.  This noise was reduced, but not eliminated, by using an expensive power line conditioner.  The dealer finally traced the problem to strings of LED lights in the room of the daughter of the customer.  These lights were on a different circuit, but, they caused problems nonetheless.  i don't know if this was by contaminating the power line, or at least in part, causing over-the-air RFI-type interference.

I was surprised when I heard noise caused by a dimmer in an extreme example of a dedicated listening room.  The room had its own dedicated power subpanel, and the lighting was supposedly on a completely isolated line.  Still, when the lights were dimmed, noise intruded into the system.  

Just as a side note ... When I turn off the display lights in my ARC gear ... REF-3 and PH-8 I get a slight reduction in noise resulting in better sound. It is slight but audible.

The room had its own dedicated power subpanel, and the lighting was supposedly on a completely isolated line.

The operative word being, "supposedly"!   

For the "I've lost count of how many times" time, there is no such thing as a completely isolated line. The closest you can get is batteries. Even then the batteries must be disconnected from the line. Even then the isolation is only partial, because RFI is everywhere. You want a completely isolated line, build your house inside a Faraday cage, with its own nuclear power plant. With just the stereo. No lights. No nothing. And with the power plant somehow isolated......    

Short of that: there is no such thing as completely isolated!   

Good stuff, guys....thanks!
