A bunch of opinions, albeit
not uninformed ones.
1) I think
that the first watt is important
in real life even for modern, average reproduction chains (i.e., the glut of modern, low-sensitivity loudspeakers).
2) I think
the trick is mostly noise
down in the low-output
3) I think
folks are even more noise-obsessed now than they were 20 years ago (which I find a bit ironic).
4) I think
it is really unfortunate
that the proliferation of RFI 'hash' from modern technology has led to both real and imagined noise issues in audio reproduction.
5) I think
that the obsession with power conditioning and esoteric power and audio cables is driven, to a significant extent, by the added noise of RFI and digital signal processing artifacts (irrespective of the low level of particularly the latter).
6) I think
that y'all'll likely disagree relatively vehemently with me on some, perhaps all of these items!
(actually, I am pretty sure
about number 6)
7) For those of us troglodytes (mancave-dwellers
, if you will
) using (very) high-sensitivity loudspeakers, the first 100 mW
is important (and, perhaps, even the most important)!
