I've personally found that the quality of the CD playback chain makes much more difference to me vs. whether a disc and hardware can do HDCD
Yeah, I have to agree. I've always enjoyed the HDCD's that I own, but I find that they all appear to simply be better recordings, and I don't know if it really has anything to do with the HDCD encoding.
My chain is an ARCAM ALpha9 Player with HDCD, Bryston SP2, Bryston 4BST, ProAc 3.8 speakers. The HDCD's sound great, but so do a lot of other great recordings that don't enjoy HDCD endoding.
