Everyone's having fun with this topic.
Although the addition of cable lifters in my system gave negative results, I would bet lots of systems here at Audiogon would benefit from them.
Everyone keeps talking about electrons and static but I think one of the biggest reasons cable lifters work (or don't) is isolation from vibration. Almost any system at Audiogon will be negatively effected if after a long listening session you walk over to the speaker cable, pick it up and shake it (gently) and set it back down.
I know it sounds like a silly experiment but in my system, with every cable I've ever owned, the effect is immediate, very negative and if you focus on sound stage, you can actually hear the cable recover. Try this for fun, it's free.
If this works for you, how much of a stretch is it to imagine that micro vibration from moderate to loud SPL's could also negatively effect that same cable? If you don't hear results of this test, it's "different" than mine :^).
I think what's important is to try it in your own system. You can used Herbies feet, cable lifters, a piece of 2X4 or whatever amuses you.
If you learn something from the test, or better yet, that it works in your system, this thread has been of value. If it all fails, you had an excuse to listen to your favorite music.
In the end, itÂ’s about putting in the work, and that's something you have to do yourself. If you're not willing to experiment, then why bother posting results (or claiming there are no results) at Audiogon?
