Upgrading wall outlets

Hifiman5;
Your experience , with the dryer , is the reason that we should also install an isolated ground to those dedicated lines !
Doing so removes any affects from the household electrical system .

Good luck .

"Furutech FT-D20A
Gold duplex receptacle. Did not expect much but a strong grip on my heavy power cords. I heard a tremendous improvement in bass and clarity. When my wife came home and asked what I had done to the system with a cheerful tone I knew that I hadn't gone crazy."

This ia the post I made on my system after I added the Furutech plug. I have a dedicated 20 omp line.

Go for it!

Oyaide R1's (best I've heard) or Pass & seymour 8200 MRI. The differences are not subtle

tried both furu ftd20a and the oyaide r1. both very good and a definite improvement over my former psaudio power port. ended up using r1 - more synergistic with my system, but you can't go wrong with either.

Speaking of dryers and improvements made, there are other appliances in your home that will definitely affect the deliver of electricity in your home. Generally anything that has a big draw on it will do this. Most notable the washer, since that barrel full of water needs some good torque to be moved back and forth, and your fridge.

I actually used to see the neon light in the wash room throb as the washer was working. I put an Audio Prism Quiet Line filter on the washer outlet and it decreased very noticeably. So I put another on the fridge outlet. Overall a very small investment that works quite well, though not perfect.

Enjoy,
