Hi,
The chord cobra 3 is good value, on the positive side it has a full bass and a fairly open mids, and nice airy top end, and is quite a warm transparent musical cable. If I was to be picky I say it lacks a little in detail, not as open and airy or fast and punchy like some cables - maybe slightly on the warm side of neutral. I say its a safe cable to use for most budget to mid price systems.
I preferred it over the vandenhul 102III, the QED and IXOS - finding it more natural sounding. I do prefer the kimber pbj though. The chord chamelon and Nordost BH would be the next level up - they are more expensive though.
All the best.
Steve.
