Hi
I will try to remain as polite as possible. Cable elevators cannot make differences unless as noted earlier the cable is woefully, inadequately, impossibly ill-built, conceived, assembled .. I think you get the gist. There is no design involved in these. Some things simply cannot make a difference like for example, shining a light on a planar speaker membrane .. If that were to make a difference, then a person sneezing would affect the rings of Saturn in some way... I apologize for the strong tone but this is one of the things that cannot work.
The truth of it is that we, audiophiles, are too willing at times to accept things. I believe that a little bit of skepticism should be interjected in our audio nirvana quests. Some things simply can't work. Cable lifters are that .. Some would call them snake oil ...
If you want your system to look nice and tidy by all means use them but don't go for any "audiophile-approved" ones. Google "Porcelain insulators"... The "audiophile" cable lifters are simply re-badged , actually badged, porcelain insulators.. Porcelain insulators, Low Voltage Pin Type , what are sold as cable lifters, go for less than $3 each or even much less I have seen box of 25 for less than $15 ... Alternatively you can buy collectors item, some of these insulators were quite fancy and even pretty ...
