CDs:Otis,Etta, Aretha....Stax/Volt comps....

Looking for specific CD advice for the best sounding digital pertaining to the Otis Redding, Aretha F, and Etta James releases...also...any decent, remastered Stax/Volt comps?
all the current reissues are pretty good....but remember....these were never audiophile recordings, so crank them up and enjoy.
There is a complete stax/volt cd compilation that came out in the early 90's. I love it.
