It is reputed to have some of the lowest noise and
distortion figures on record (Martin Colloms) yet,
last night when I was listening to a particularly fine
1958 recording of Grieg's Concerto in A minor
(Solomon), I switched from the Technics on the TLS80s
to my 2A3 SET on the Fidelios and got a much better,
more *exciting* (more listenable) sound. As the SET
(according to the pundits here) produces enough
distortion to bend light and the Fidelios have little
or nothing outside the range of the human voice, I am
intrigued as to what's going on?

Is it me?

Almost certainly.

Plenty of people prefer the colour saturation turned up
on the their telly
for that 'technicolor' look. So actually preferring
some types of distortion doesn't seem that unusual to
me. That's why so many like vinyl,
after all.


It's all 'reproduction', and it all 'distorts'.

It could just be that certain modes of reproduction
produce a more satisfying result. A painter's rendition,
a musician's performance, a poet's meter, a writer's
(etc). These examples may result in a more satisfying,
more *realistic*, experience of the original event,
despite the fact their efforts are not technically
facsimiles. Is distortion always bad?



The instant you touch a volume control you distort the
sound to suit your needs....


Contrary to the author's apparent belief, it is possible to play a
recording at the same SPL as it was recorded.

However, if you took what he said seriously, the instant you choose a
listening location at a live concert, you distort the sound to suit
your needs.



I refrained from adding to a recent thread that was getting a bit
carried away with the subject of 'realistic reproduction of an
orchestra' in one's own listening room - fuelling the notion that there
is only one true, accurate (distortion free) rendition of (presumably)
every single piece of music ever composed or created. Farcical, to say
the least - I have as many as half a dozen *different* recordings of
some works and can therefore distort the sound (and runtime) by choosing
whichever one to play...
