Joe it is ironic that I find the opposite to be true so far as dynamics in complex music. The power supply of the amp will dictate whether or not it runs out of gas on busy and dynamic passages of full orchestral music. The VT-100 MK2 provides in the neighborhood of 500+ Joules filter capacitance which would make it hard to imagine that it would ever run out of steam and probably would compare favorably with most 200 watt solid state amps out there. My D-115 Mk2 by comparison has a total of 280 Joules and I NEVER hear congestion or compression during busy passages. But then again my speakers are very efficient and have a very flat frequency response across the band with no serious impedence dips. My MC-60 while not as extended at the frequency extremes as most solid state amps, still deliver the power. Filter capacitance is over 250 Joules each amp, they have been modified. They also never sound congested or compressed and offer better bass slam if not definition than the D-115 Mk2. The tube amps, to my ears, offer a better rendering of the micro macro dynamic swings that are evident in live music. This is another area where they excel. The one area where solid state is generally better is in the area of bass slam which eludes most tube amps of similar power. High frequency extention and smoothness is also quite good in the best designs. That said, I still think the ARC amps are superb in the area of bass definition. It is my understanding, although I havent heard myself yet, that OTL amps are even better in this area. I hope to find out soon. Once again a matter of taste and preference.
