Wife stepping on speaker wire

Is there an consensus as to whether SC lifters make a difference
I've never detected any on wool or synthetic carpet or wood floors. A bit on concrete though but still not night or day.

Schubert, I don't know what SC lifters are, but I find porcelain isolator with glaze are clearly best. I have yet to find a cable including power cords that is not improved by being isolated. Furthermore, one per cable is best.

Tbg, SC= Speaker Cable.

Thanks for the info, never heard the one per cable before.
What make do you use?

Suspending cables and cords from fishing line from eye hooks in the ceiling works for me. Kills two birds with one stone. It's what the pros do.

Set out orange cones in the room.
