Replacing generic RECEPTACLES

@elizabeth ....Thank you for your explanation on the Brass outlet covers...I am going to take you opinion and fly with it...Thank you for saving me about $ 615, on those 2 carbon fiber covers from Oyaide. I will now use Brass dual duplex , and a Brass single duplex with my 3 Furutech GTX-d r 

@folkfreak    Thank you for sharing your experience with the Oyaide plates and covers..I really am glad now that i didnt buy them ..

Just for the record, not intending to judge too harshly, ceramic wall outlet covers sound much better than brass ones. But not for the reason you think. It’s also partly why ceramic feet/cones sound much better than brass ones. Hint: it’s good old physics. And it has nothing to do with magnetism.
