Interesting observations. Thanks Dave. But how can that be
reconciled
with the all amplifiers sound the same argument? :-)

I've not tried the A21 in any version, nor can I recall anyone
claiming that, "All amplifiers sound the same".



You either have a poor or a very selective memory, Jimbo - or you
perhaps were wise enough not to read all the posts from a former
subscriber here (the Roseate One) who frequently made the claim (as
he
slid further into what appeared to be an AV/can't be arsed with
'audio'
vegetative state) that all amplifiers did more or less sound the same
with the preconditions that they were 'good', solid state and cost
300
UKP or more.


Well, perhaps it was sometimes claimed by one poster in a message that
*someone else* had said "All amplifiers sound the same".



No, it was clearly stated on more than one occasion that 'all ss
amplifiers sound the same' by the poster (obliquely) referred to above.
When I queried this, I was told 'all *good* ss amplifiers sound the
same'. When I further queried what constituted a 'good' amplifier, I was
told 'anything 300 quid or over' - or words very much to that effect.

(Actually, FWIW, I have no problem with that argument - AFAIAC they do.
:-)



But I can't recall anyone making such a statement with no qualifiers.
If
you can, perhaps you can post the details of who, when, etc. - i.e.
give
the date, time, title, etc, of the posting, and the full wording.



Ain't gonna happen....



My recollection is that a more common claim was something like "all
qualifiers amplifiers sound the same (or indistinguishable) under
specified conditions of use.". Many people have said, this, from PJW
onwards. Alas, it then seems to be routinely changed to remove all
the specifics/qualifiers by someone else who dislikes what was said
and who wants to argue.

I think this is the a version of the 'Straw Man' debate technique. :-)



Possibly, but I have seen the phrase 'Straw Man' misapplied to so many
arguments that I no longer take any notice of it.

From the Whacky Wiki:

"A straw man argument is an informal fallacy based on misrepresentation
of an opponent's position. To "set up a straw man" or "set up a straw
man argument" is to create a position that is easy to refute , then
attribute that position to the opponent. A straw man argument can be a
successful rhetorical technique (that is, it may succeed in persuading
people) but it is in fact a misleading fallacy, because the opponent's
actual argument has not been refuted."

Does not apply here with the 'all ss amps sound the same' claim - that
was stated quite clearly by at least one poster who was very Rosy and
not at all Straw...





But in this case the differences
in the output impedances of the two amps might perhaps produce
different frequency responses with a load like the 57.



There ya go for starters...


Indeed. A point that has been made countless times in the past. And so
far
as I recall, not contested by anyone who made the qualified claim I
give
above. Since I can't recall anyone making the unqualified claim, I
can't
say if they'd have objected to what I wrote. But if you can give
specifics
I can check. :-)



Can't do it; wont do it - if nothing else, I'm busy 'grass-seeding' atm!

If it helps to quench this particular point of debate I'll happily
retract with a coppy 'OK, maybe I'm wrong then' as it isn't really worth
pursuing, in my book...
