Replacing generic RECEPTACLES

@tomic601....Who is talking about a 20A on a 15A Line?

@ Elizabeth. Kudos to you for disassembling a receptacle. I used to do this for a living and never contemplated doing that. I think the receptacle you described is a little over the top, but glad you like them. In a high current draw situation, if the connector, being the cord in this case, doesn't generate any heat at the connection,  you're good. As I said earlier, a lot of small tweaks put together, can and does make a difference. My view is, as I said, you have diminishing returns after a while. I'll have to say, you're really getting down to the nitty gritty. I guess if you know you have done everything you can to improve your sound, it's very comforting.

My point is: If you already have a 15A service with receptacles where you need them and there is not already  a host of other devices plugged into that circuit - that circuit would be most adequate for your cdp and possible other devices. I can understand upgrading the receptacles and to a point, power cords, but installing a new 20A circuit for a CDP or even a CDP and one or two other components, is nonsensical....my professional opinion...Jim

I should make clear on my previous statement - that is if your home is relatively modern with a good electrical system, or is an older home with a professionally upgraded electrical system. I can see the value in having a dedicated 20A circuit for your high draw power amps and large powered subs, however....Jim

@audiosens The wall plate is a tweak I've always thought was just an appearance thing.
