Toward the end of the final day in Las Vegas, I found Kalman Rubinson entranced by the sound of Shirley Horn singing and playing piano in the Audio Research room at T.H.E. Show. A pair of the new Mk.2 version of the Wilson Sophia speakers was being driven by ARC's Reference 210 monoblocks, a Reference 3 line stage, the Minnesota company's new Ref CD7 player, with cables from Shunyata and Cardas and AC conditioning by Richard Gray. I was equally entranced.
