I tried raising cables off the floor for about a year. Tried them back on the floor and heard no difference. Michael Greene seems to believe in risers, but he also told me the type of metal the screws are made of which hold down circuit boards in components would also affect the sound. YMMV.
Does raising speaker cables off the floor really make a big difference?
My cables are laying on the floor (in a mess), would raising them off the floor really make much of a difference? The problem is they are quite wide and too long
