Any one try the new Synergistic Research BLUE UEF Duplex receptacle?

Anyone who wants to see if customizing a wall socket makes a difference or not, keep your current wall outlet, but stick some strips of fo.Q TA-102 (from Japan via eBay) tape on it. Cover it as much as desired. Total cost about $10 worth of the piezoelectric tape, for your jaw on the floor.

What is its purpose?

Background and features: fo.What?

fo.Q was developed by Kiso Industry Co., Ltd., of Japan, through its affiliate Titecs Japan Ltd. According to Kiso’s website, the company develops and markets “industrial chemicals, materials for civil engineering, and environment-related instruments and devices.”

fo.Q is a piezoelectric material -- i.e., it generates an electric charge when subjected to mechanical stress -- and was designed to improve the performance of audio and video equipment by converting solid-surface resonances into heat. Unlike, say, Stillpoints ERS paper or Shakti Stones, it is not designed to absorb, redirect, or diffuse electromagnetic interference (EMI) or radio-frequency interference (RFI).

Kiso states that fo.Q has at least twice the damping power of conventional damping materials. They say that, as resonances increase, conventional materials become less effective, but that the opposite occurs with fo.Q: as resonances increase, so does the degree of damping.

Kiso also states that fo.Q won a funding grant from the Japan Science and Technology Agency, a Japanese governmental agency responsible for the development of science and technology. The material gets its name from principles of acoustical engineering (i.e., physics): f stands for formant, o for zero, and Q for quality factor, or resonance.

$32 on ebay.  $95 at cableco.  Sounds about right.

Use of small strips of fo.Q material is highly recommended. As the top plates of US spec receptacles are usually held by only one screw the edges will unavoidably resonate. Adding strips of fo.Q across the edges of the top plate to the wall or outlet frame will damp this resonance. Be careful not to overdamp however as this can deaden the sound. This phenomena may also be why slightly loosening the top plate screw can sound better the having it fully tightened
