evs ground conrol tweak


I am interested in trying this tweak out. I would like to here from other members who have tried these as to what improvements they experienced. I have heard both good and bad about them, including someone saying that after a while with them in there system that they seemed to have a negitive effect on the sound of there system, any opinions are welcome, thanks, Kent

Blake here Ron. Small world. (I am the guy that sold the Ground Enhancers to Rcrerar, LOL).
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.
Hdm and Rcrerar have responses I fully agree with, except I love mine.
And yes I am a clarity and upper frequency freak.
Mine also filled out the midrange a bit where my highly A/C conditioned system was a little lean. Perfect!

I really did not like any on the RCA ground terminations of the preamp.

I made my own. Though the EVS are very reasonably priced, considering so many tweaks want $300 for a bucks worth of parts...

There are all sorts of ways to make variations on this tweak.
I added ferrite and extra wire at the end of the short wire to the terminals..
Over on Audio Asylum in the "Tweaks/DIY asylum" are all sorts of discussions about them.

I have the tails on the negative speaker terminals, and at the amp negative terminal.
I also have one on the ground of my headphone amp (using a ring termination just fitting over the outer ground of the connector)
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.
