Maybe they make a difference, I don't know. However, I'll ask you to look at the pictures from various audio shows (CES). How many of the mfgr's are using cable lifters when showcasing their equipment? All, some, none, few? I don't know if Dave Wilson uses them at shows, but if he thought it would make his speakers sound better, don't you think he would use them and recommend them for use when you purchased a pair of his speakers? Think of the rooms at CES, can you have more static-inducing foot traffic? Just some questions I have regarding cable lifters.
