No prejudice there.


Yours or mine....??


Good question. The claim that a 10 watt amp sounds
louder and cleaner than a 100 watt amp only makes sense
if there is something very wrong with the 100 watt amp.
When it turns out that the reliably-audible defects tend
to cluster around the 10 watt amp, then doesn't the
person making the claim become suspect?


Why shouldn't a 10W amp into an efficient speaker sound
as loud as a 100W amp into a less efficient one?


Why would anybody in their right mind present this as a fair comparison
of amplifiers?




Who did?



But all that amplifier weirdness aside, the high efficiency speaker can
only have equivalent bandpass if it is vastly larger.



Who said anything about 'bandpass'?



Why would anybody in their right mind present that as a fair comparison
of speakers?



Who said it was?



I've got it - let us make a big fuss over the fact that a 7 liter Cobra is
faster than a 35 cc motorbike. Obvious proof that 1970s technology is
superior, right? ;-)




And you've got the brass arse to call me 'illogical'...??

(I guess it must be ****ing with rain in Merkin Land as well....)
