In my quest for the right DAC I keep coming across HDCD. I can't work out whether I should make sure my DAC had HDCD capability or not. Did the format take off? I've had a quick look through my CDs and haven't noticed HDCD written on the back of them which leads to me to think that it's not being extensively implemented. The HDCD web site gives a different impression though! Do most/all modern decent DACs (stand alone or integrated) implement HDCD and do many CDs? Thanks.
