Maybe this is a bit off-topic, but I can't see how The Nightfly merits such a high dynamic-range ranking in the list presented by the OP. It's mostly a constant volume level, except for fadeouts and the end of "The New Frontier," where all the instruments except the electric piano and cowbell drop out.
I think there's got to be more dynamics in some of the other recordings mentioned, especially the Telarcs mentioned in the last posting.
