First, I want to point Cooper et al to an interesting post I found about a DIY-er finding a Burr Brown DAC on the inexpensive Panasonic f85:
Second: krazy, not to beat a dead horse, but this was a key point from Cooper's post, and since you said you were new to all this, it's worth highlighting:
"If DVD-audio & SACD aren't important to you, and you don't have an HDTV, then these benefits will be diminished. Also, this is a single-disc unit."
That last part is really worth assessing, about the changer. If you really want a decent new CD player with changer that's a very fine DVD player, than the inexpensive Panasonic appears to be able to do the trick, and to my knowledge it is one of the few (if not the only) highly rated, well-reviewed 5-disc changers that gets good marks for audio and video while offering some hi-rez capability (DVD-Audio). You will miss out on SACD (read that forum post linked above) and the Denon has qualities beyond SACD and its DACs to recommend its price differential. I don't know what the bass management is on the Panasonic, but would imagine it's superior on the Denon. The Denon 2200 and 2900 get great reviews for the finer points of DVD playback. But unless you already have HDTV or feel that you know, already, what these finer points are, then this Panasonic appears to be a best-in-class model, and it really may address your overall needs better if you want a changer. Looks like it's DACs are great too. (Great DACs, man.) I anticipate upgrading to an f85 myself soon. Were I tempted to shoot the wad on the Denon (a move I applaud in others), I'd at least force myself to do some home-testing of the two models, given the significant price differences.
Meanwhile we all await a lowering in cost of universal players, which probably is not far off.
