I guess it really depends on the speaker; two runs of speaker cables on my single post Avalon Ascendants was spectacular but two runs of cables on my Acoustic Zen Crescendos didn't yield the same results, jumpers worked better...
2 runs of wires or 1 run w/ jumpers
I am considering trying Anti Cables level 3 7' speaker wires. Am I better off using 1 set of wires with jumpers or running 2 sets of 7' wires?
