Estelon's XA Diamond

Demonstrated with Concert Fidelity amps and preamp, the Bricasti M1 D/A processor that I review in the February 2012 issue fed by a Loit CD player, and, like many rooms at CES, wired with Kubala-Sosna Elation and Emotion cables, the Estelon XA Diamond ($64,000/pair) produced sound to match the elegance of its styling. Improvements over the standard XA that I auditioned at the 2011 CES include a diamond tweeter, improved midrange unit and woofer, and changes to the constrained-layer cabinet construction.
