James,
I added thisplayer to my system at the same time as a 2900 and I am as pleased as i could be with it.
Because I also have the 2900, the only reason I bought it was to have a 5 disc changer that would not be too much of a downgrade in audio quality from the Denon when I just wanted to pop in 5 discs and forget about it. It has not dissapointed, and actually, it has done nothing but amaze me. I cannot speak to the DVD-A or SACD abilities, I leave that for the Denon, but for Redbook CDs this would be the best player I have ever had were it not for the Denon.
