Upgrading wall outlets

A few other things that can have an affect ; microwave ovens , HVAC units , some remote controls , flourecent lights and small appliances .

Good luck.

I have noticed meaningful differences as well. Can those who used Furutech, vs Oyaide vs others comment on the character of the differences? I have used standard, Porter pots, sound application, and the new synergistic tesla and find them all to be quite different. I have used the sound application primarily for the past 2 years.

I noticed a great improvement from porter ports, much like a power cord or interconnect upgrade

Going to hardware store and getting new outlets (spend a few bucks on the better grade) should provide a tighter connection and possibly better performance to almost any system. But getting anything more exotic or expensive than hospital grade? Placebo effect. Spend your money on music.

I respect your opinion regarding the “Placebo effect”, but I don’t think so. I don’t want to start an argument however for the record, (in my opinion), in blind tests that I ran with several other audiophiles, a difference could be heard using some exotic or more expensive outlets other than hospital grade. To take it a step farther, as long as the outlets were not gold, having them cryogenically treated enhanced the outlets even more after initial break-in.
