Can anyone define 'Slam' in the context of audio power amps?

The ability to deal with sudden short lived transient sounds - preferably
without affecting the rest of the output of the amp. Normally acheived with
good PSU design and big power reserves and capable of transient output well
beyond the units continuous ratings.


This doesn't feel right. A transient capability well beyond the
continuous rating of an amplifier speaks of poor design and an
inability to handle large signals well. In fact it is one of the
fake-power-ratings refuges of the charlatan - the old instantaneous
peak power syndrome beloved of Sinclair Radionics.

Any really good amplifier will be able to handle full power
more-or-less continuously - certainly for several minutes - without a
problem.

If slam really isn't just another piece of marketing nonsense, then it
must have a reality based in a particular sound produced by an
amplifier - that would make it some sort of specialist device for
music production, not Hi Fi reproduction.
