brass outlet covers...anyone try them? Sound good

I'm with Albert & Tom ( Audiotweek ) on this one.

Anything that physically touches or connects to your componentry becomes a transducer for mechanical energy. This mechanical energy alters the sonics that we hear and can be excited at a variable rate acoustically. If one doubts this, try hooking up a cable to a distortion analyzer and watch the distortion measurements jump around as you move or "flick" or tap on the cable lightly.

This is probably one of the reasons why cables that make use of mechanical damping can sound "blacker" than cables that are more sensitive to microphonics, either airborne or mechanically coupled.

With all of that in mind, i really don't know how much "damping" a wall cover can offer, but i do know how much more metal rings compared to a composite material. Given that the power cords are mechanically coupled to the outlet cover / wall receptable box, maybe a mechanically damped metal shielded plate would work best.

Anyone want to market a highly damped composite material outlet cover with bits of metal impregnated for shielding purposes? With this kind of stuff, the sky is the limit.... Sean

I found some very heavy cast brass covers at a second hand store years ago. they are all 3/16" to 1/4" thick in a lovely design. I use them in the living room with my stereo, but I NEVER put them in there to alter the sound. Lucky for me they are very nice loking, and what they do to the sound is obviously not actually hearable. What soap I bathed with, and what shampoo I used may have more influence than outlets....
Are you 'super' tweakers displaying other psychotic symptoms, IMO.

Elizabeth, If you are still using the brass plates and they are installed on grounding type electrical duplex outlets chances are the brass plates are degrading the sound of your audio system. You may want to replace the brass plates with nylon outlet cover plates.

I made some power strips probably fifteen years ago using some black plastic boxes and ordered some really beautiful cast brass plates for the fourplex boxes only to find that the solid brass made the sound just bright as the devil....A couple of nylon screws and some tape on the backside of the plate took care of the problem....Aluminum doesn't have that sort of problem BTW....

I've become so confused by the issue of the sonic attributes of outlet covers on audio that I've just taken them off and let the the open outlets act a mini diffusors. Cheaper and less angst. :-)

I bet matching light switches in your dedicated listening room could only add to the superior sonics of those wall plates.
