I agree with others who have said "it depends on the speaker".
In my travels, I stopped at a dealer and auditioned a Magico floor standing speaker at first driven by a solid state power amp with a very high damping factor; it seemed in that setup the Magicos needed to be driven pretty hard to "come to life". When the other sound room became available, the salesman moved the Magicos and played them with a powerful tube amp and to me, they sounded significantly more "musical", had better bass and didn't sound so "in your face".
As I've moved up the line with my equipment, it seems that it's the "synergy" of all the components in the chain that seems most important.
