I think wikipedia says most of what's needed to know...

There are a relatively small number of CDs which have been encoded in HDCD, and a correspondingly small number of players have been sold which are capable of decoding them. However version 9 and above of Windows Media Player running on Microsoft Windows XP is capable of decoding HDCD on personal computers with a 24-bit sound card.

The 24bit sound cards range from between 200-500$.
So yeah, obviously those CDs seem to be HDCD, which makes sense because, as you mentioned micster, Panasonic used this song for testing their TrueHD sound.
