Hi George.
Good luck with SACD, I got my first SACD player a little over one year ago, and never regretted it.
I like the smaller labels for SACD's, I think they have better sound quality than the Sony/Columbia stuff.
Things I like include Christy Baron (jazz vocals) on Chesky, Alison Krauss (country/pop) on Rounder records, Eric Bibb (blues) on Opus 3. Opus 3 has some good jazz too, they have a sampler you might want to get. Audioquest has some good blues SACD's. I like my Claire Martin SACD from Linn. I just picked up a Keven Mohogany SACD from Telarc that I like, he covers some old Motown tunes.
Hope this helps, I have a bunch more, but thought this is a start.
