Kudos to the remastering engineer of these previously released tracks for this compilation. Originally, this was a Library CD and sounded excellent in my car audio which made me excited to hear it on my tube based stereo listening system. I was not disappointed. The CD is full sounding, good overall sound balance, and features deep and balanced soundstage. Overall sonics are a joy to listen to. Afterwards, I bought a regular issue Etta James CD for more music from this compilation. The difference in sound quality was night and day. The redbook CD was typical - flat, thin, etc...., Simply, sonic differences was a good FM station versus a portable transister AM radio. The outstanding remastering enhances the listening pleasure. If you have a better than average music system, this CD will be a treat to listen to. After listening to the Library copy, I bought myself a copy. Thank you San Francisco Public Library (so support your local public library too!).
