Best SACD / DVD-A below $500 True DSD only

Does the MARANTZ DV6400 have true dsd and how does it compare to others? Especially the Denons (and Toshiba 9200 for DVD-A). Also, is the Denon 2900 noticably better than the 2200?
I just returned my Denon 2200 I paid 630.00 for retail, and bought a Phillips DVD963SA for 500.00. I'm very happy with it's picture and sound. I'm wating for some new cables to see how it really performs!
