I agree with that, but with Avalon you sort of have to know Roxy Music's music style first. I wouldn't say it is for everyone. It is an very well done SACD and I really like it, but it's basically moody, brooding, 80s music and may not be to everyone's liking. Though I like it, I don't listen to it that often either.
I also like Godsmack's Other Side - pretty well mixed, nice clean sound.
One that I haven't heard yet, but would like to get a hold of is Jazz at the Pawnshop. I have the redbook CD version and it is already probably the best recording I've ever heard. The only problem is, the SACD is quite expensive at around $50-60 (2 disc).
