Zaikeman's and Awdeeofyle posts are well stated and right on,IMO. I'd just add that HDCD is an improved redbook CD format, but it is still 16/44 technology and thus does not have near the potential of either SACD or DVD-A, each of which have several times the storage capacity of a redbook CD. My Levinson 360S DAC does decode HDCD, and while I like it, it's a relatively minor improvement over a "regular" well recorded CD. In fact, I think the best CDs are those done using JVCs XRCD2 system.
Could it be that MS wanted the HDCD technology for some other purpose? Cheers. Craig
