I was wondering about the HDCD format. I have a few older CDs encoded with this and they are some of the best audio quality in the collection...especially a couple by Joni Mitchell that make the CRS+ sound awesome. Apparently, though this is just in the production quality of the CDs as I doubt that any CD player I have is HDCD capable. This article seems pretty skeptical of the format and whether it improves sound quality. Any opinions....?
