I've compared and noticed an audible difference between none, toilet paper rolls, cardas maple blocks, and Shunyata Dark Field elevators. Any of the risers were better than none. Between them it was more a matter of tuning than being necessarily better than each other.
Mapeshade cable lifts or any cable lifts?
Do the cable lifts under speaker wire actually help improve the sound? My cables are wide ribbon Verbatim Cables. Thanks...Edward
