I tried a pair and you can find quite a few comments on the MartinLogan Owners website http://www.martinloganowners.com
Basically they are made from standard Belden 8247 coax (similar to TV coax but larger) and though they are very detailed and produce excellent microdynamics, I feel they lack lower midrange and bass response; making them impractical for use with a fullrange stat like a Quad 57 (in fact I tried them on a friend's 57's and my own CLS's)
Any good low capacitance (under 40 pF) speaker cable would work better for your purposes. I'm partial to Purist products, but any low strand count cables (i.e. NOT Cardas) will be good with stats.
