I am upgrading my dvd player, The Panasonic RP-91 A great player but I want to get into SACD audio and I have read very possitive reviews on both the Denon 2200 and the 2900. As of right now I am more inclined towards the 2900 because of the amount of music that I listen to, but I am wondering how much better can the 2900 be compared to the 2200?. I currently have the Marantz 8200 receiver, the Paradigm studio 100v3 and the 570 center channel combination. Should I hear a difference in sound quality with this set up, if in fact there is a difference between the two players?. You could say I'm a critical listener but not an expert in anyway.
