You know the album and the music, so this is just about the sound quality. Having owned the original LPs back in the 70s, I know what the noise used to be like on this album. All albums from 1970 and before were like that. When the remastered CD came out, it cleaned up the ambient noise and made the album way more listenable--it was a dramatic improvement. The SACD version takes it even further with a 5.1 surround mix which seperates the instruments, lowers the ambient noise to nothing and really lets you enjoy the musicians. They can't make the flat recording of the vocals sound any brighter, but at least you hear them as well as possible. It's probably not overstating things to say that the 5.1 mix is relevetory, as it really does let you hear the individual instruments much more distinctly, yet is done in an aggreeable way that doesn't sound at all gimicky.
