I'm using some standard rca cables for my sub and I know I need to get a better cable. I'm using Van Den Hul/ Qed and Nordost cables for the rest of my system. Only thing, I'm not sure if it's worth spending very much on a subwoofer cable. Some people say it's not worth it, as a sub only transmits low frequencies. Others reckon it is worth spending more. I was going to get a chord calypso or a qed interconnect. Someones offered a Monster thx cable at a much better price. Having never compared subwoofer cables, does any one have any advice on whether or not it is worth spending alot of money on a sub cable? I'm using an MJ Acoustics Reference 1 sub connected up to a Denon 3802 amp and it sounds a tad too boomy. I'm guessing it's the useless standard interconnects.
