HDCD'S

I’m new to HDCD’s in fact I hadn’t even heard about it until I purchased a player capable of decoding an HD disc. I’ve asked around at the local cd shop and a few used outlets, no one seems to know much about it. I’ve searched the internet looking for a list of HDCD titles and came across one site called Fish Records in the U.K. Is there a outlet here in Canada or in the U.S.?
