What’s your vote for the most ridiculous, overpriced, and useless tweak?


My vote: Furutech Outlet Cover 105 NCF $220, with “special crystalline material that has two “active” properties.” https://www.thecableco.com/outlet-cover-105-ncf.html

Piezoelectric wall outlet covers work and they work extremely well. You can test this yourself with fo.Q tape, stuck onto the outside of a regular outlet cover. A cheap way to re-arrange your thinking.
^^^ Try pasting the inside of the wall outlet cover with PPT Total Contact and see what happens.

I’ve been designing and selling audiophile products based on piezoelectric crystals for a wide range of audio applications, including but not limited to power plugs, walls, windows, room acoustics, for more than 15 years. I also designed and have been selling a wall outlet that acts like a resonator for around ten years but who’s counting?  No big deal. Maybe for someone living in a cave.
I agree with Frank. But first coat the inside with fo.Q tape and then apply the Total Contact onto the fo.Q tape. I found that to be even better, and it’s easily removable if you move out of the house.

My main wall duplex outlet has SR graphene treated screws for the wiring, fo.Q/TC inner plate lining, fo.Q outer plate lining and AVM paint on the internal wiring and casing. Unused outlets are plugged with PPT Stop-It! duplex plugs. I think it was also blasted with the SR Tesla coil when I sent it to SR for treatment. I’m happy with the results.
