Perfectimage, not the price quoted $350 is for an analog Type 2 PAIR. You have a single digital interconnect, yes? That is the Type 4, I have a list of $150 for a 1 meter run unbalanced, no specified increase for XLR connectors.
Pardales, it sounds like you have the Type 5 speaker cable, which listed for $55/ft plus $100 termination fee. That would put your 6 ft pair list at $760. Info is from a 1996 Stereophile magazine, Vol.19 No. 4
