If some of you were following this last year, Liberty Cable, a cabling provider for the installer crowd, liquidated their high end "Z500" series of cables, and I picked up what were probably the last two sets of 4M (13ft) speaker cable. I've enjoyed them for a while, and really they are some of the most beautifully built speaker cables I've tried. Silk braided sheathing, interchangeable gold plated brass connectors (banana / spade / pin), and OCC core + OFC wiring in a 10AWG construction.

I'll probably regret selling them, but I just don't see the point of having them sit around when someone else could enjoy them. So offering them up exclusively to my AC buddies.
I'm willing to part with the two pairs I have. As mentioned above, they are (4) pairs and each pair comes with (

spades, banana, and pin connectors that screw on. Unfortunately for one pair I've lost (4) of the banana's. Meaning you could use bananas on one end, but would have to use spades or pins on the other. Not a big deal, but if important to you, please buy the first pair with the full set of connectors.
I'm selling these at cost, which was about $32 for a pair + $12 for USPS priority mail shipping (medium box) to you. I.e. $45 a pair. I honestly don't think a better set of speakers exists for $3.50 a terminated foot!
If you want BOTH pairs, I'll even knock another $10 off as that'll be my shipping savings!
Any other questions, please let me know.
