[NTLK] AW: Transistors vs. tubes

Just let me chime in a few words:
from an engineering point of view there is one fact which makes the main difference in the sound of
valve/tuve amps and transistor amps: this is the overdriving behaviour.
Ok, using the latest technology with DSP (Digital Signal Processor) you might be able to simulate this special behaviour of a
tube amp, but never using a pure transistor amp without additional sound processing.
Despite of all these pure technical and dry facts one thing remains:
the feeling you get if you see the tubes glowing...

But transistorized devices definitely can't do one things tube devices never
had a problem with: Prove the physical law that light travels faster than
sound.
Whenever you turn a tube radio on, first thing you see is the glow in the
tubes.
The sound comes way later.

Ok, ok, I'll go to sleep now...
