Genesis, Yes, and Pink Floyd are my favorite bands. $1000 isn't really worth it though. So I'm trying to find out if there is any way to find their mulitchannel recordings for cheaper. I have one of their SACD's, it is good but not amazing as far as 5.1 mixes go. So I don't want to spend so much for them, I might get a couple. Yea, I agree stereo SACD's are not generally worth the bother, I have a couple and they are only slightly better than the CD.
I have 4 Yes 5.1 discs. Fragile is terrible, the rest are pretty good.
I have Dark Side of the Moon which is excellent. I'm not aware that Pink Floyd has done any other 5.1 mixes. I wish they would release more. I'd love to have some of the Beatles albums in 5.1, but I don't think they have any. It's unfortunate that no one can do a 5.1 mix for famous artists at least.
