Home made cable lifters.

For the absolute best cable/floor isolation, take fishing line and suspend them from the ceiling. Space the lines a couple of feet apart and keep the cable a few inches above the floor. You might start with a good clear monofilament or fluorocarbon line at 10lb test.

Then try different line strengths and colors, and heights off the floor to get the best sound. Clear tends to sound the most transparent, and saturated colors sound darker. The stronger the line, the more damped the cable will become, and that may sound heavy. Of course your results will depend on the cable, the floor surface and the type of music you like.

When dialed in, this approach is guaranteed to have the best performance for almost no cost, and provides much experimenting fun between listening sessions. For others who may have tried this already, please give the Capt some helpful advice.

PS, Be very careful, as these lines can be hard to see, and someone might get tangled and cause injury to themselves or damage to your equipment.

PSS, I am not associated with any manufacturer of fishing products.

Sorry, I forgot to mention a very important aspect of implementing the fishing line to cable interface.

Do not under any circumstances tie the lines too tightly around the cable, as it tends to constrict both frequency response and soundstage size. Leave just a little room for the signal to breath.

Also never use a metallic line, since it could act as an antenna to capture RFI and add it to the signal.

Just a couple of more observations about the fishing line to cable interface I described above (11/16).

All other approaches recommended so far have some dense material between the cable and floor, and this can restrict the formulation of the lower portion of the sound image between the speakers. The line to the ceiling gives the maximum clear space for the image to form.

Even more important, the fishing lines work especially well for classical music since the cables are suspended on strings.

Mmakshak, Thanks for appreciating my "strings" for classical music. (See 12/04 and 11/16 above)

I have indeed lifted power cables. It is referred to as "power lifting". It is best to hold each PC firmly in both hands, and always squat and lift with the legs, not the back. Power lifting can be dangerous, and should never be done with the PC plugged in as it weighs more than when unplugged. Once lifted, you can shake the PC gently to remove and residual EMFs, and you should also remove and kinks to ease the transition of electrons along the wire. The PC can then be gently lowered back into its environment for operation. One last tip... it is not well known, but all PC manufactures put the writing on the cable to indicate which direction is up. Try it both ways if you don't believe.
