I have seen a lot of ideas concerning Cable lifters

I recently bought the Fog lifters by Audioquest.  I listened from my chair as my son installed them.  I perceived an immediate in the blackness of the background (noise reduction), better depth and bass definition and a truer rendering of vocals and acoustic instruments.  These are the kinds of bugaboos that you don't notice until they're removed.  Highly recommended.  Besides, you can always return them if expectations aren't met.

Electric fence corner ceramic insulators. Very workable design. Ten pack ~$12 at tractor supply.

ok... I'll restrain myself here except to say

LOL

May I add....LMAO!

"I doubt any of them have more that a used Sanyo they purchased off of eBay for a sound system."

All you Sanyo owners, please raise your hands.

I use glass insulators. You know the kind that go on poles by the railroad tracks. I don't hear a difference in the sound but my system isn't high end (resolving). I figure, if they prevent popping from the static I create shuffling around in my socks..it might help. Mostly I don't have to bend over and move them to vacuum (not like it happens all that often but..). It does prevent the heavy cable from sitting at an angle in the wall or component. If it provides a better connection that has to be good right. Besides, they look cool. Stop sniveling about what other people do. Unless your a PHD electrical engineer and studied the effect, we just don't know. Maybe the practical side is to try different stuff and have fun doing it. Now chill out and listen to some music.
