Neal - I'm finding this a fascinating thread. Please update it from time to time.
Like you, I'm a big classical music fan. I'd like to suggest a recording that I think will test any system: the Karajan recording of Salome with Hildegard Behrens. Dark, somewhat unusual sonics but with lots of detail and dynamic contrast. I think my system is decent but this HvK recording has been exposing its flaws mercilessly. I suggest you use one of the louder tracks as a test - any speaker that can do pretty well with it is one fine piece of equipment.
