Best Audiophile Album in terms of Dynamic Range and Mastering Quality?

+1 for I've Got the Music in Me - I think it is one of SL's best sounding albums. Period.

Also - Umbrella - Rob McConnell Big Band Jazz - D2D

ANY of the new Original Source releases from DG. All re-mastered recordings from 50's, 60's, 70's - at least so far - tape to cutting head. Can't get any purer than that. And the sound is incredible.

Crystal Clear - if you can find any - 45rpm D2D

Analogue Productions - they have remastered a LOT of stuff - I have yet to be disappointed. 

I've always thought my original copy of Rickie Lee Jones debut album was recorded very well(WB).  I have tried a "fresh" copy from Mo-Fi.  While still good, it seemed to be missing something.  Maybe that was because it was thicker vinyl and my VTA on my table wasn't readjusted or something. 
Also, I think The Siegel-Schwall Band's 953 West on Wooden Nickel Records is  really good, too FWIW.

Sublime "Sublime" the CD is fantastic
