I have always enjoyed the Stockfish XRCD24's. "Closer to the Music" collection, Sara K, (and others) spring to mind. The cd covers say they are 24bit recordings. When I ripped the XRCDs to hard drive I changed the default rip setting from 16bit to 24bit in the hopes that I would not "damage" the ripped version. Haven't done any A-B-A comparisons but decent original recordings are always appreciated.
