I have purchased a number of these (at CES's) and found the reproduction to be really amazing - especially the remasters of some great older recordings, like the Reiner/Bartok 'Concerto for Orchestra'. They can be played on any Redbook playback system.
I'm not as versed in digital audio technology as you folks, but I am able to understand the process in concept, and it does seem unique.
