I really like the Porter Ports as well.
I decided to upgrade the outlets in music room several years ago, and because I have almost all Echole cables and power extender that uses some sort of Oyaide outlets, I thought I should try to the top of the line Oyaide outlets to complete the chain.
After receiving the new outlets and installing them I was immediately turned off, but I gave them several weeks to burn in, but still wasn’t in love. Still have these Oyaide R-1 (I think) outlets in my arsenal, but have replaced them plus another spot with Porter Ports and love them.
