tube Watts vs solid state Watts


Hi folks, can anyone explain to me why 20W tube amp is more powerful than a 20W solid state amp? Further: a 20W pure class A amp is more powerful than a 20W class B amp. Why is that? I've always thought Watt = Watt.

Interesting concept. Can you explain that a bit please? What is in this case the high torque engine: the tube amp or the pure class A solid state amp?

Chris
And what about pure class A solid state Watts and class B Watts? Many audiophiles (who are often non techies) say that a 50W pure class A solid state amp is comparable to a let's say 200W class B amp. Is this bullshit? Why do people give that kind of deceiving comments?

Undertow: what is your explanation for these a bit counter intuitive findings? So those people who say that tube Watts and solid state Watts are not alike should be taken seriously?

Ok folks, so the point is here not that the tube Watts are more "powerful" than solid state Watts in absolute terms (when measured) but they are more powerful in terms of psycho acoustics. It's the subjective finding that not all Watts are the same. So when someone is saying that a 20W tube amp is more powerful than a 100W solid state amplifier you have to correct that somewhat by using abovementioned explanation.
