Upgrading wall outlets


Curious if anyone has found much difference in sound quality upgrading wall outlets.

Ok, I'm not looking to start a flame war. But can someone tell me why the power from the plant to my house is going to be noticeably improved by an outlet? I have an open mind some please tell me.

Well, believe it or not. The premium outlet (like PS Audio's PowerPort) that I am using does make a big difference. In fact, it was one of the best upgrade I have ever made in my audio life. I am not an engineer. I can't explain why. The premium outlet has better metal and it also allows very tight grip on the power cord. That may explain the sound improvement.
