Do a search over at AA, there was talk on this "JD100s" a while back. As I recall a reputable Jolida dealer chimed in an advised that the JD100s was an overseas version of the JD100 and was generally inferior to the unit sold in the US. The JD100 "H" on the web site you posted looks to be a standard JD100 and a used one given the price. I have never heard of a JD100 with HDCD capability. I would proceed with caution if you are considering buying either of these units.
