I don't use cable lifts but I have experimented with other cable treatment methods. Here's a cheap easy tweek to try. Fill four sealable sandwich bags with sand. Place one under and one over the speaker cable at the nearest point to the speaker where the cable rests on the floor and see if you hear a difference.
Mapeshade cable lifts or any cable lifts?
Do the cable lifts under speaker wire actually help improve the sound? My cables are wide ribbon Verbatim Cables. Thanks...Edward
