Lifters ForGetting Cables Off The Floor, Worth It Or Snake Oil

randy-11  Your statement is quite strong. It presupposes that somehow all of us understand how to determine what "math" is required for this problem and then even more for us to successfully do the "math" that would provide the correct answer. I assume there are some who frequent this forum that have that ability including engineers, scientists, audio designers, etc. But, as a guess, I'd assume most of us in here don't have that skill set. For me, I know I'm not one of those who can do the math.

Now for the obvious question, No, I've never tried this tweak so I've no skin in the game.

Finally, for me, with tweaks, (and I've done few) I just try them and if they make a worthwhile change, I'm pleasantly surprised. Because, like you, better sound quality is my objective.

is it that hard to learn?

or run a real test

Good for OCD solve but that's about it

I have a dozen ceramic cable lifters in my system. I don't notice any musical difference using them or not but I do like the way they look holding up my 25' long interconnects from my preamp to my amps. I wasn't expecting to hear much improvement but they do make a visual statement.

  I use cable elevators to separate any interconnects from power cables.  This is only in a couple of spots where crossing couldn't be helped.
