I recently purchased a 5.1 surround sound system. Naturally I needed to load up on some 5.1 CD's. I did alot of poking around, bought a few. Some impressed me some did not. Then I rememebered getting a SACD Sampler from Rolling Stone magagzine. Aerosmith's "Sweet Emmotion" is on it. Without a doubt , this is what SACD's should sound like. Alot of SACD's sound like an entirely new mix. Many things are lost (like the bass) and others are too prominent in the mix. This one just kicks. When the bass comes in and the song starts to rock, your'e SO glad you have it in SACD!!! The album is a classic, there should be no doubt about that. This just improves upon it. Highly recomended.
