Recommendations for 20 amp electrical outlets

squared80 - Have you done the experiment or do you just know or don't understand?

It's like a lot of things--it depends upon what you have in it and what you  want to get out of it.

Your experience with the new outlets is interesting and I thought about doing this with my dedicated 20 amp line.

Have you considered using grounding boxes? I guess it’s helpful to ensure you don’t have backflow contamination from any returning current flow along the grounding wire, strictly a 1 way path sort of thing

I too did not know if receptacles would make a difference, but instead of just accepting that fact; I ordered 7 different receptacles and did a many month  comparison in my system and home. I kept the receptacles I liked and improved the sound, and gave the others away to friends.

To me this is the proper way to see for yourself, not blindly saying they make no difference.

By the way, a good friend loves the Cardas 4181 that I gave him so much, he wired his entire listening room with them; and had 2 dedicated lines installed.
