Upgrading wall outlets

Start with some Porter Ports..Very inexpensive and work very well..You may never have the urge to go any further...I put mine in a few years ago and have been totally happy with them and have moved on to other things to worry about.......

Countingbackwards well put!!!

Countingbackwards, well put except that the outlet isn't a filter at all!

True, it is a convenient means for connecting an electrical piece of electrical equipment to available electrical power.

Important factors for a good connection.
*Electrical conductivity of material used.
*Contact surface area.
*Cleanliness of the connection.
*Contact pressure.

Other factors that come into play for receptacles used for powering audio equipment.
*Ferrous or non ferrous material used.
*Contact plating material used.
*Materials used for the body of the receptacle that holds the contacts in place.

The average convenience receptacle outlet used in home construction cost about 79 cents. It uses a steel ferrous back strap and nickel plated contacts. Contacts have bare minimum contact pressure. Receptacle body is made of cheap plastic.

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.

If you were an engineer you wouldn't be able to explain why either. At least based on generally recognized science.

You are not improving the quality of the electricity coming out of the wall . You are improving the connection to it

This is what is well put, not the reference to outlets serving as filters and cleaning things up (which they don't).

And of course improving the connection will only help if the original connection is somehow deficient, and if the deficiency is somehow great enough to affect the signal path despite the filtering and isolation which the power supply of each component provides between the ac and the signal path.

Disclaimer: I have not tried any audiophile-grade outlets, so I express no conclusion about them, just a lot of skepticism.
