I recently bought a pair of used Epsilon References version 4. I have never seen a woven metal jacketed cable before, they are very cool. Also nice WBT spades.
Pure Note has opted to go to a different design called Cerulean. The Epsilon Refs. are far more musical than any cable I have yet to audition (I have not tried the Ceruleans, hear they are even better). These cables are very life-like and open. Perhaps a tad thin but not hard or bright. Excellent focus and wide/deep stage. At used prices there is no equal, IMHO.
