Just curious if anyone has ever used this one. Recognize it sounds like voodoo, but I know it makes a noticeable difference in my home audio system (have a few EMI/RFI treatments), but have no idea how it would impact a car in the real world. Not exactly big claims, and $ probably better spent elsewhere, but just curious (so no flaming )

Works well in my home audio, too noisy in my TT to try, not enough
resolution.
