I'm curious as to what the "crystal ball" shows for the future of
digital amplifiers (aka "Class D") for high-end audio systems?

After researching the topic last night on the Internet, it is
certainly intriguing. Surprisingly, though, I find little recent
discussion of the topic on this and related newsgroups.

To aid discussion, here are a few links to overviews and reviews/
info on three example high-end digital amps (if you know of other
audiophile-grade digital amps to add to the list, do mention them!):
