Some posters have claimed the Cary upgrade has cured a few bugs as well. When I was doing my internet research before buying a month old 11a, I got the distinct impression that the sound quality of the Anthem D2 wasn't quite up to that of the 11a, and that I would need to step up to a Classe 800 at about $8K. The biggest complaint with the 11a was that the automated room correction S/W on the chip Cary uses isn't accurate, and indeed the Cary manual recommends using a tape measure and SPL meter.
