...and I'm trying (probably badly) to help! HDCD is complex. The extra information buried in the bottom bit is used for various purposes and some of them really have no direct analogue to proper 20/24-bit recording. All my HDCD's (>60, including various excellent Linn discs) have been transcoded to 24-bit files with DBP and I think they all sound great and better than the straight (non-HDCD) playback of the original 16-bit file. They used to sound great when I had an HDCD CD player. However, given the choice I'd rather have a 24/96 DVD-A (I have the HDCD and DVD-A versions of the King Crimson albums for example). Now, these aren't identical mix masters but the DVD-A's sound better to me. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
