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

My wife and I suspended every cable from the ceiling with fish line in our system, the effect was far from subtle, it was jaw dropping! You can actually see the sub power cable fish lines sway or dissipate the vibration, no snake oil with the fish line system. 

Any lifter on the floor is not going to yield sonic improvement or very little.
Suspension from the ceiling is another story. but like already posted to each his own.
