Okay, I'm a little confused. If I usderstand HDCD correctly, it includes 4 extra bits of information. This will allow 20-bits of information on an HDCD. There are a lot of HDCD players on the market (Denon 370 being the most popular) that have 18-bit DACs. Isn't this totally defeating the purpose of HDCD? Aren't you going to loose 2 of the extra 4 bits within the DACs?
