Cardas Clear vs Nordost Frey 2 vs Chord Sarum T Speaker Cables

There are too many options in the market for speaker cables and I have narrowed it down to two actually, which is the Cardas Clear and Chord Sarum T. I have included the Nordost Frey 2 as it was recommended by few people. Nevertheless, after reading some responses about a full loom which is required for optimal performance, interest has somewhat fizzled. 

I am aware there are many other worthy good alternatives such as Audience, Transparent etc. but would appreciate if experiences are only focused on the Cardas Clear and Chord Sarum T. I am currently using Chord Signature XL which is very good, but am looking for the endgame before I call it a day. As I will likely purchase used, demo is not an option. 

Any experiences from people who have tried or compared the Cardas Clear, Chord Sarum T and Nordost Frey 2 in their systems would be appreciated. I am looking for neutral-bright, clarity, speed, good bass and treble extension. Dislike a smooth cable that roll-off the treble and making it sound smooth. I want an airy extended treble and would want to hear all the micro-detail and air, and a textured deep bass with good punch, slam and dynamics.
