Kubala Sosna Emotion Speaker Cables - 4M (13.1') spade to spade.
Condition of these is excellent. Rated 8/10 only because I'm not the original owner (and take Audiogon rating guides seriously.) These are the best sounding cables I've heard in my system. Hard to let these go, but a move to Vandersteen speakers requires a pair of bi-wire cables.
From Robert Levi's Positive Feedback review:
"The Emotion speaker cables are more than the sonic brothers of the interconnects—they are as transparent as any speaker cables I've heard. I've spent an enormous amount of time listening to these cables, and I'm still not sure what they sound like. Every time I detect a coloration that I attribute to the speaker cables, it turns out to be something in the front end. They work well with other brands of interconnects, but can pass unwanted colorations right through to your speakers, so be warned. When they are used with the Emotion interconnects, the sound is extremely close to ideal—even, smooth, and alive."
