That looks awfully like Audioquest Type 2 or 2+ speaker cable in single-wire configuration, only the photo makes it look Apogee purple whereas my Type 2+ is closer to brick red.
There are four conductors, two of them smaller in gauge than the others. A single-wire configuration has each smaller-gauge conductor twisted together with a larger one to make twin double runs of the same equivalent gauge.
I have a couple of lengths of Type 2+ in smaller systems. Price was about $2 a foot, as Mofimadness says. Not bad-sounding for the price.
