evs ground conrol tweak

You'll never know till you try it in your system.

Search for the DIY versions and experiment for yourself. Very little cost involved.

They did not work for me. No question they changed the sound and, to be honest, at first I thought they were very impressive.

Their effect in my system was to accentuate details, definitely more air around instruments and voices, which all sounds good. In the end, though, it was too much. The overall presentation was kind of "hyperdetailed" with sounds being pulled apart and isolated in what was, to me, an unnatural way. More hi-fi but less realistic sounding, if you will. And definitely less "relaxing" to listen to on music that should be relaxing to listen to. I found that, overall, I just did not want to listen to my system as much with them in as with them out.

For those that value detail, soundstaging, imaging and qualities like that above all I can see how someone might like them. But to me, both voices and instruments ultimately sounded less natural and realistic with them in place.

I own a pair. My thoughts basically mirror what Hdm had to say. At first I was quite impressed with the difference they made, but after awhile the sound of my system seemed disjointed, or more correctly disconnected, less of a whole so to speak. In fact the person who sold them to me described their effect in exactly the same way as Hdm does. Maybe they are one and the same person, I don't know. My speakers are bi-wireable and supposedely you really should have two pairs for use with bi-wireable speakers, plus another set for your power amp. Then there are ones from a competing company( Audio Prism) that are supposed to be much better,certaionly more expensive. That comapny also makes versions for your unused RCA inputs on your pre-amp, so now you can seee how what seems like a very rasonable investment initially can escalate very quickly. My pair is at a friends house right now. I loaned them to him to see what he thinks, as I value his opinion when it comes to all things audio. He reported not being able to hear any diffeence at all and he has a high resolution system. If you would like to try them out I can get them back anytime from him and send them your way for very little money. I live in Canada so the shipping will probably cost you more than I would ask for the grouind control devices themselves. Just a thought.
