Maybe somewhere, sometime Mikey recommended a piece of gear he doesn't sell. Good for him if that happened. Unfortunately, that does not fit with his industry black sheep, expose industry lies and rip offs, trust me, join the Tribe schtick.
Again, I ask how is this marketing hype any different than what the big bad industry insiders promote? "passive RF/EMI filtering technology utilizing rare earth minerals in a polymer matrix, as well as treatments to the live and neutral leg to reduce magnetic flux, as well as a crystal wafer resonating disc which activates in the presence of AC power."
No doubt we all need a crystal wafer resonating disc, maybe several, to make our systems sound great.
