oz350Oz,

I have found HDCDs to sound very transparent on regular 16 bit decoders, however I agree they often sound thin. Maybe we have different ideas about the term transparent. To me, if refers more to the midrange and top end than the bass. Not that bass can't be transparent, it's just that bass transparancy comes from cues that are higher in the frequency range (skin of the drum, fingers on strings, etc.) 20 bit decoding always sounds much richer to me. Also I think dedicated cd players typically have more drive (16 or 20 bit) than the common dvd player.
