"Must-have" SACDs Out There


I just got a Sony XA-777ES SACD player. I was initially disappointed with the performace. I could not hear much difference between the CD layer and SACD layer on the Sample CD that comes with the player. I went out and bought the "Norah Jones: Comes away with me" SACD and started listening, then I begin to realize the advantages of SACD. As far as I can tell so far, the music is smoother, less harsh, and has a overall quieter background. What else should I be listening to? What are the "must-have" SACDs out there?

The SACDs that I like best include:

Norah Jones, Come Away with Me
Diana Krall, The Look of Love
Peter Gabriel, Shaking the Tree (excellent 2 channel)
Steely Dan, Gaucho
Pink Floyd, Dark Side of the Moon (great multi-channel)
Miles Davis, Kind of Blue
Willie Nelson, Stardust (sounds great, but I'm not a big WN fan)

I look forward to getting more SACDs of these same artists. I also have some of the Telarc Jazz and Classical samplers which are pretty good. There does seem to be a wide spectrum along the lines of mix quality and the ability to get the most out of the format. Acoustic Sounds seems to be a good source for SACDs. Interested to see other choices as well.
I would add to that list, Peter Gabriel "UP" Roxy Music "Avalon" , Patricia Barber "Blue Cafe" and "Companion", also the new Mike Oldfield "tubular bells" is a great multi mix.
