I also would be wary of the Emotiva, they don't have a history of making a good processor, quite the contrary! Most of theirs don't work right at all!
The D2v and AVM50v are good units, the Marantz is nice for a lower price, if you have the funds you can go to the Meridian models but they use a two box solution now, Krell makes some great ones (wish I still had my Evo 707!) but it costs $30k.
I think for now technology has sort of settled out and almost ever processor has replaceable HDMI boards so they can be updated (I did this with my Classe SSP-800) so they do hold value much better than before....
