GONK: You da man !!!!
You have cleared up a good deal of my confusion. Thanks. I'll opt for the 990.

(1) I want the options and for sure dts, as we are doing some archiving, tring to put material of our own acquisition (big bands etc) on dts. I think we'll be successful. (hopefully)

(2) To be able to process at 96KHz/24 bit sounds like a good idea if one can produce one's own material and play it. I can, though I would need another player in the liv room to do it. I can now make 96/24 on my Alesis ML9600. They refer to CDs in that format as "CD24's"
You've shown me that HDMI-DVI is a non issue.

(3) Since you can contrl HDMI from DVI and vice-versa I guess I don't see what the problem is. Is there one?
