Our Verdict 
The Xen digs up much detail, but lacks the enthusiasm of the very best cables
Digs deep for detail
Rather mundane delivery affects timing and dynamics
Reviewed on
The Xen uses Ixos's Gamma Geometry construction. Never heard of it? Ixos claims that it helps to reveal more low-level detail and produce greater dynamics. 
Well, the cable certainly does a good job of unearthing detail. We're more concerned with the cable's rather pedestrian delivery. While the top cables express their desire to take the music and run with it, the Ixos plods along, lacking enthusiasm. Timing and dynamics suffer as a result.
