Wikipedia Article on "Tube Sound"

http://en.wikipedia.org/wiki/Tube_sound

I just stumbled upon this article.... sometimes I don't get wikipedia.. isn't everything supposed to be 'cited'... ?

Quote:

Push-pull tube amplifiers can be run in class A, AB, or B. When in the class A region the distortion will be as described above, but while in class B the distortion will be SE like. Also, a class AB amplifier will have crossover distortion that will be typically inharmonic and thus sonically very undesirable indeed.

I personally have never heard this before (not that i insist i'm right).. aren't some of the best solid state amps out there Class AB (Simaudio, Symphonic Line, Blue Circle) ?

The thing about Wikipedia is that it is not necessarily true.!!

You can always edit it.

Class B also has crossover distortion (all the time) and class AB only has crossover distortion when driven hard (when the output tubes cut off). I don't know what the business of class B having "SE sound" is about.
