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

**Tell you what to do:

1) Find a nice pair of difficult to drive, full range loudspeakers. A pair
of AR9s, some old Infinity's (Kappa 9, RS1.5, RS2.5, etc), Linn Isobarics,
Duntech Sovereigns, Crown Princes, B&W 801, 802 (et al), KEF 105, 104 (et
al). would all be suitable candidates.
2) Now find two, similarly powered amplifiers. One, a decently designed BJT
amp, with a flat frequency response and adequate current delivery for the
above-mentioned speakers. Rotel, Krell, Arcam all make suitable products.
Now find a low bias MOSFET amp. Perreaux and several other manufacturers
make suitable products.
3) Listen to some music which has fast, dynamic, percussive sounds.

After this, you will probably understand what I mean by the term: 'slam'.
