Hi, Just bought the JMLab Electra SW900 sub. Very happy with it right now. I am using a normal coaxial cable to connect to the LFE channel to AV receiver. Want to upgrade to a good quality subwoofer cable. Any suggestion. I am willing to spend up to US$150 for a 16 ft cables. Anyone have good advice on which one to buy??? Which sounds the best??? I am thinking of Qed (silver reference), Cobalt sub cable, Monster M series. Any others??? Hope someone can help.
