Amp wise I would say Sunfire, B&K, and Rotel. As for a pro/pro that would depend on if you want an actual pre/pro or a mid to upper level receiver.
Even though the technology rapidly changes I don't think we'll see another sound format change for home use any time soon. Dolby, DTS, and THX have to realize that the average home will not fit more than 7 speakers and a sub. The majority of homes with surround sound only haveing 5 speakers and a sub.
The HVD disc may not even be used for home entertainment purposes. It could just be used for computers.
