The issue I got from a Berlin shop was the TBA CD reissue. Indeed a very wide dynamic range, has to be played loud to hear the full range (oh my lucky neighbours ....). I think JVC had a hand in initiating this recording. Sounds like a typical direct-to-disc album, very clear and detailed, no distortion, not even on the electric keyboard, guitar, and bass - I wonder how they did it, by direct inputs or miking the amps. Sounds like the band is in the room. Must be a terrific soundstage when played back on high end equipment. The music is nice, similar to that cooperative band Ritenour and Grusin had, Friendship.
The problem with many classical recordings is that they use very large rooms that narrow some of the dynamics with small ensembles. Too much room ambience in many cases, at least for my taste.
