Don't know about that. Schumpeter argued (in an analysis of western
capitalism) that economics measures well-being by the standard of living
(variously, average incomes and consumption). This is best achieved by
maximising production and consumption. Buddhism (his 'foil' and the basis
of the small thesis) does not measure well being as such, but consider
that it is maximised when consumption is minimised. Basically this means
that well being is not dependent on consumption - the 'given ends' (a
difficult concept, granted, but take it as live in comfort perhaps) with
the minimum means. An example might be hifi - why do we need all this
stuff?! Large is a sort of antithesis, not genesis.

Indeed, though I'm not sure that can be seen as a reason for using SET
amplifiers. Their output power may be small, but as they are so inefficient
their power consumption isn't. And the permanent dissatisfaction with what
one already has (which is the basis of the audiophile philosophy) is the
antithesis of the Schumpeter ideal. My Quad 405 may be "large", in the sense
that it has an output power significantly greater than I really need, but it
probably draws less energy from the mains than a SET amplifier does.
Furthermore it has powered my main audio system for over 25 years without
needing any replacement parts, so in terms of the energy used in manufacture
and transport it has had a fairly low impact on the planet.

Mmm. I too have a 405 which has given sterling service. If it is so
efficient, I wonder why Peter Walker, not notably a waster, included
that large, expensive heatsink at the back.

Prolly as their products went world-wide aimed for hotter climes?..

Prolly. And equally prolly to ensure that prized longevity.
Overspeccing for durability is perfectly legitimate; I was just
checking if Looser is a standard issue anti-SET hothead or knows how
to engage his his mind in gear. He doesn't.

I suspect he may have had IHFA707 in mind... ;-

That was the test which came into use to try and deal with makers inventing
bloated power ratings. The snag was that it defined that any test had to be
done with the amp 'pre conditioned' by being run at 1/3rd the rated power
for an hour before the power was checked at the rated amount.

Useful as a test for weeding out amps with bogus power claims, but had
little to do with use for most music which - in those days at least - had
crest factors well over 10 in most cases. Although I have my doubts how
common that is nowdays.

Slainte,
