Dynamics and Microdynamics

Perhaps this isn't an amplifier, but a speaker issue instead (or both). Here is my observation:

I recently listened to the same piece of music (Chopin, Etudes, Pollini, Deutsche Grammophon 431221) on two different systems (in the same room). System A: VTL MB-450 monoblocks in tetrode mode, driving B&W Nautilus 802. System B: Classe Delta CA M-400 monoblocks driving Wilson Watt/Puppy 7. Source, pre-amp, and cabling was the same.

Now here's what was strange: While the Classe/Wilson system was clearly better at microdynamics (ferreting out the hidden gems of melodical lines within the overall structure of the pieces), the VTL/B&W system did a better job at conveying the dynamical punches (from ebbing to swelling, up and down the tonal scale), i.e., the guts of the musical structure. From memory, when I listened to these pieces live, both mico-and macrodynamics were clearly audible, not just one or the other.

Also, system A sounded a little thinner, system B a little warmer. So my question: Any explanation for this? While I understand that the refinement you get with an accurate representation of microdynamics is system-dependent (and the Watt/Puppys are more expensive speakers than the Nautilus 802), both systems should have been able to get the macrodynamics right, or not? Or does this have anything to do with tube (VTL) vs solid-state (Classe) technologies?

Thanks for any insights.

I have heard the 390, 380, and transparent cables together, the Classe (flagship monoblocks and CAM350) and B&W together, but not the Wilson Audio and VTL. I believe what you heard was mainly the effects of the amp. Classe amps tend not to be the warmest nor the champs at macrodynamics (in its price range). I do remember them revealing spatial details very well though.

Some people run the 7s with low power tubes so I would think 100W is more than sufficient, although having never heard the Wilsons I can't be sure. You can look into Manley amps as well. I think they combine refinement, warmth, and tube power for their price very well. I don't think they're as good as the Lamms but you do have to pay more. It certainly gives you a different combination of sonic attributes nonetheless.
