I have a denon 2910 and cary audio DVD6, both connected to a denon 2805. the cary is a recent purchase after 2 very lengthy demo trials. i still have the 2910 for SACD & DVDA, as the DVD6 does not support either format, although it will play a DVDA disc, just not at the high res rate. the cary was purchased based upon its exceptional sound quality playing redbook cd's. the differences between the 2 players are quite pronounced. for redbook cd's, the cary has an exceptional sound quality, to the point of at times rivaling sacd sound quality from the denon (this is quite dependent on recording quality). the differences between the cary's analog and digital output is also evident, with analog output being exceptional. it's not exactly a fair comparison, as the cary msrp is nearly 3x that of the denon, and while the denon is a very nice player, the cary is a 35+ pound tank. i snapped up a demo unit as the dvd6 is now supposedly out of production, and the dvd7 has an msrp of something like 4000. so far have not noticed any real difference in picture quality between the 2 units, but i bought the cary for its exceptional redbook cd sound.
