To elaborate, the cross-over region introduces a highly non-linear 'kink'
into the transfer characteristic of an amplifier at exactly the audibly
most critical point. No amount of obfuscation can deny that basic fact.
The smartest techniques to ameliorate the situation include 'moving' the
kink away from the zero signal region by various methods and 'stretching'
the kink so its effect at any given level is reduced.

And yet many modern amplifiers when properly measured at 1W (regardless of
max power rating, and price) still exhibit miniscule levels of THD and IMD.

Miniscule ? Care to give a number ? Can you even give an example. I've never
seen such a number quoted on a spec.


The theory is correct, but not necessarily a real problem.

Most likely corrected by massive negative fedback but I'll bet that the 100mW
THD is still MORE than the 'just prior to clip' THD.
