"I maintain that above a damping factor of 50 then you gain next to nothing. In fact, extremely high damping factors may be indicative of very high amounts of feedback and just like an amplifier with a specification from 10 Hz to 400 Khz I am wary of these kind of amps"
Shadorne - I agree 100%.
Sane designer would try to design an amp with not more than few percent THD before feedback and then improve it using feedback to only about 0.1%. Finaly he would limit bandwith to what amplifier had before feedback was applied to prevent TIM. 100kHz bandwith as a result might be nice to prevent phase shifts but 400kHz is unnecessary and might be harmful.
Damping Factor is often limited to about 100 by the choke in series with the woofer. Also DF measured in static condition doesn't mean much. Transient response of power supply (due to usage of good capacitors like slit foil etc) might be more important.
As for "More Power" I would suggest "Less Power". On average 200W amp doesn't sound as good as 100W amp that cost the same and is only slightly louder (it needs 10x power for 2x loudness).
