Amazon's classical department search engine is pretty good, but only has two buttons for media type: "CD" and "DVD Audio". Does anyone know why they don't have a third button for "SACD"? I've sent them some feedback but am curious. I'm considering buying a SACD player because (1) they cost about $400 as compared to $900 for a hybrid player and (2) I only am interested in classical music. But I would sure appreciate being able to browse for SACD titles first.
