Ehh, Jimi Hendrix in stereo is kind of a waste it should be 5.1! I would buy it in 5.1, in 2.0 I don't think I will bother.
The Moody Blues SACD's blow me away, they were from the quad mixes in the 70's. The music takes on a whole new 3D life in 5.1 I'd love to hear Radiohead OK Computer in 5.1, that would be epic! Too bad that album was butchered when it was mastered, all the dynamics got smashed and compressed. It's hard for me to enjoy now, the sound quality is so bad. Even with the 20th anniversary edition, they kept the terrible compressed mastering yuck.
