Upgrading wall outlets


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

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.

The Hubbell HBL8300H see page 10 for a cutaway view of the receptacle.

This is the receptacle that Albert Porter has cryoed by NASA and sells as the Porter Port....

Note:
No ferrous materials used.
Non plated brass contacts and non plated brass back strap.

The HBL8300H not to be confused with the standard HBL8300 which uses nickel plating on the contacts and back strap for use in corrosive areas.
