Role of HDCD in an upsampling world


I am wondering about taking the plunge into upsampling players or possibly an outboard DAC.

My question is what will that do my HDCD discs? I have several hundred or so, and more on the way. These are some of the best sounding CDs in my collection and the music is nearly all of my favorites.

How can I best take advantage of HDCD and upsampling?

My system:

Arcam Diva 92

Rouge 99 Magnum (Sylvania chrome dome 6snt GTs)

Bryston 4B ST (Soon to be departed, likely for new Rouge Zeus)

Thiel CS 2.3

Cardas Golden Reference cables, PS Audio Lab II power cords, Power Plant, Ultimate Outlet, DH Cones and squares.

Thanks for this and all the advice in the past.

If you are looking for newer technology, why not SACD? Either stay with CD (upsample?) or go with SACD. HDCD? Where should HDCD go? If even SACD/DVD-A can't survive, will HDCD have future?
Bluefin, for whatever it's worth, Bill Gates seems to think so. I think HDCD has more of a future than either DVD-A or SACD. I just don't know which. While HDCD's may not be as "good" as the new alternatives. I would venture that to date, and for the foreseeable future, more HDCD's will be pressed than SACD and DVD-A combined.
