There's another CD format (Phillips?) that's just beginning to turn up. I'll wait and see about that and cease to lust after SACD altogether. Mui Muchas Gracias!
Purple Book, aka Double Density(2000-2001?)? I know there were a few HDCDs(early 90's?) out there, maybe some of these older better versions are starting to catch on as vendors try to avoid Sony's BR and it's higher royalties(or so I have heard)
