Ser ganska tokigt ut! Varför skall man sätta en antenn på kablaget?
Ganska underhållande med en recension som faktiskt sågar produkten:
"Over a series of sighted A/B listening sessions, I sometimes reckoned that I heard a touch more body and low-level dynamics in the mids. But the differences weren't tenacious enough to trust. In unsighted (not double-blind) A/Bs it became clear that I could not dependably identify when they were in or out. The same held true over periods of long-term listening. Since I was unable to reliably detect the possible differences in or out of the various contexts explored, I have to say that the Ground Control devices aren't for me. Your mileage may vary."
