> Hi all,

As already pointed out, an analogue system with enough headroom won't
clip the signal. It is also almost impossible to generalize what will
append when an analogue system go in clipping. This will depend on what
kind of hardware this is (class A preamp, class A, AB or B amp, ...), on
what kind of feedback it use ("normal" audio amplifier with a lot of
feedback, or power "operational amplifier" in open loop like a guitar
amp, ...), on the technology in use (bipolar, j-fet, tubes, ...), on
the actual implementation of the whole thing inclusive its supply, and
even on the quality or power of the components in some cases.

As example, when you push guitar amps in clipping at full volume, half
of the clipping you can ear is, with some brands, not the clipping of
the electronic, but the clipping of the power transformer. That sounds
very bad -:(, and that imply you may have to change often this
transformer when such amps are used to play blues or rock like styles
of music.

Even without going to such extreme cases, the actual implementation,
which is always a compromise between money and quality, will determine
the sound of any analogue system. And this is the most difficult part to
simulate -:)
