Haven't had time to read it, but yesterday I received my copy of the July Stereophile where Kal Rubinson, "Music in the Round" columnist and HH, reviews the new Dirac equipped Emotiva processor. A quick peek at the conclusion showed it promised to be favorable(for Emotiva and Dirac) in its detailed comments.
Have you read it? There is a direct comparison between M's MQA and Emotives dirac sound, using the Ravel demo used in some MQA demo's (sadly not mine :-( ) I will leave the punch line for those who buy the magazine or wait online.
