I asked because it's the floor *construction* that determines if and what kind of lifters/isolators you might need.
In a floor like yours, inductive interaction from laying on (or very close to, even if there's a carpet) a grounded surface like a reinforced concrete slab, is not an issue.
What *might* be an issue is vibration, and usually this will affect both speaker cables and interconnects (unless you have carpet in which case the interconnects are pretty well isolated by the carpet.
Cable lifters that can transmit floor vibration may not be that much help. A better solution in that case will be swimming pool 'noodles' if you can find them in a decent color ;--) Slice them into 4" - 6" lengths and string them onto your cable. (Gray pipe insulation can also be used but needs to have the seam held together with contact cement.)
