I can not sing the praises of this receiver high enough. I spent an awful lot of time researching what Airplay capable receiver to buy and settled on two. I had originally considered getting the Denon 1912 but Batpig's thread on avsforum.com convinced me to upgrade to the 2112 for the better calibration system. Having a hell of a time trying to decide between this and its competitor, I ordered both and decided to try them in my home hooked up to a set of fantastic Energy Take Classic speakers. The result: the Denon blew the competitor away. Now maybe the competitor's MCACC calibration system just can't compare to Denon's incredible Audessy MQ and perhaps with some tweaking it would have approached the Denon in sound quality but I figured if the competitorcouldn't get that right, what else didn't they get right. Whereas the Denon is crystal clear with every note distinct and crisp, the competitor had a muddled, muted sound to it. Both I and my spouse could not believe the difference. I honestly don't think I would have kept the speakers had I gotten the competitor first, blaming the speakers rather than the receiver for the mediocre sound.
