Hi, I see some members have sighted there concerns about the potential for this DIY ground control to ruin, destroy, or even blow up your amp. This simply is not my experience at all. I put this out to the Audiogon family to share with those who like to tweak and do cheap DIY projects like myself. And I for one like to hear the good bad and indifferent of opinions. Now as far as the ground cables I made or the ones that Audio Prism sells. Both are very simple in design. I just made mine out of different wire and a different spade. And without the unbleached cotton outer jacket. This is far from mystical and the stuff of legends, but I must admit it is strange how well it works (in my system). So all I did was satisfy my curiosity about "better ingredients" with a very cheap tweak that seems very safe to me, and keeps my wallet out of danger.
