evs ground conrol tweak

The pair I have are mounted inside my speakers at the crossover input. While not an absolute OMG experience or anything, they sure improved things, and in my case without making anything worse. There was an increase in dynamic punchiness - not exactly a uniform increase in the entire dynamic envelope so much as mainly through the midrange. But, it seemed to 'raise the roof' a bit with dynamic outbursts throughout the mids. The crescendo in a SACD copy of Rhapsody in Blue hit a whole new level of dynamic expressiveness. Al Dimeola's deliberately flared electric guitar notes on his Elegant Gypsy CD have a whole new level of cool factor. Bass also seemed to be a bit better articulated. These things are staying in my system and I may be ordering more down the line.

Walker Audio just came out with a bare wire version of this tweak. As with everything Walker Audio, it’s expensive

I started with the EVS version and it worked so well I bought the AudioPrism version just to see if a more expensive version would work even better. IMHO the AudioPrism version was better, so loaded up on them. I've got RCA terminated Ground Controls on my subwoofer and CDP, and bullet terminated Ground Controls on my amp.

I gave the EVS version to a friend who has really good ears, and he went nuts with what it did for his system.
