High end AC plugs/receptacles...


Just want to get a feel for what the community here thinks about AC plugs/receptacles such as those from Oyaide, Furutech, Isoclean and Shunyata.

Are they worth it?

Thanks in advance.

I have Oyaide R-1's and the WPC-Z cover. I think the cover is as or more important than the outlet. Never did I hear more difference than putting in the wall outlet and cover. When I added more R-1's downstream even w/ Oyaides outlet strip MT_UB
the change was nowhere near as audible and dramatic.
