The combination of the Denon AH-D7000 with a good solid-state amp does indeed work very well for classical music. Mine is fed from a Luxman P-200 headphone amp and the combination sounds incredibly synergistic.
I'd like to point out though that with classical material, the source is as important, and with that in mind, I prefer to listen only in the SACD format, which benefits from a much higher resolution. Obvioulsy, listening only to the stereo SACD layer. Currently, I'm using the Sony SCD-XA5400ES SACD Player as my source, again with great results.
... I found all I was looking for in the Denon AH-D7000. They have the richness and acoustic qualities and sonority, but also deliver on the highs.
... Strangely, I actually prefer the 'soundstage' (thought I almost hate discussing it) of the D7000. It's more the width of the presentation, and for classical I prefer things a bit closer. Obviously this is all user preference and opinion, and I just like slightly more intimacy, or less space. When I watch a performance the musicians are usually in front of me, not on my sides, so I find extremely widened stereo effect to be unrealistic. The D7k puts the musicians right in front of you.
There it is... there are four, with one clearly above the others for personal preference only. Many will probably tell you the LCD or T1 or HD800, whatever. Try them all out if you can. But don't miss testing the D7000 with a good solid state amp. Wounderous.
