Speaker cable lifters.

Hey gang. What are your takes on speaker cable lifters ? Is there any truth to this ? I was thinking about purchasing some for my Straightwire Crescendos. Which are very thick speaker cables btw also. Diameter is over 1 in. Also my B&W 800 Matrix speakers are also quad wired so there are about 2 speaker cables for ea speaker that sits on top of the other. Would that matter ? Thanks in advance.
