“… it’s clear already that the SA TT-7 Power Grid Interface is an amplifier’s best friend in that it cleans up harmonic textures yielding a smoother and more musical tone. I think that it’s exactly what a line filter is supposed to do. Jim Weil obviously has mastered his craft.”

“AC line conditioning is far more critical to audio quality than speaker cables and interconnects. Given an accessory budget of $5000., I would spend it in a heartbeat on the SOUND APPLICATION CF-X conditioner and simply make do with my old cable.”
