And that surprises you?

Hence, they are simply not "audiophool mods" .

Lets get this straight. You consider improving the performance of an amp
an 'audiofool' mod? You are even more stupid than you first appear to be.

You stinking pile of pommy excrement.



and not explained by components becoming obsolete.

** Nearly all such factory changes were due to that happening or being

Ah - it's 'nearly' now is it?

Only electronics design engineers understand this - not piles of
stinking **** like you.

Which one told you this? Obviously one who realised how gullible you are.

Quad themselves offered upgraded boards at one point.


** Quad never said any of the factory changes made the 405 sound better.

In fact, the original 405 was claimed by Peter Walker to be audibly
without flaw.

So YOU are making him out to be a LIAR !!!.

And you appear to think of him as God...

You one stinking pile of lying, pommy excrement.


Peter Walker certainly didn't like closed minds.


** So he would have hated your stinking guts.

As I said we got on well on the several occasions we met. When and where
did you meet him? or are you simply making all this up - again?

Get cancer and ****ing DIE you criminal pig.

** FFS,

Quad wisely provided a way to limit the output VOLTAGE of the 405 so that
an ESL57 was unlikely to arc internally.

The ESL57 was originally intended to be used with a 15W to 20W amplifier (
ie a Quad Mk2 ) and had a nominal impedance of 16ohms.

The 303 pushed that a bit with a peak voltage of +/- 31V.

405s had the same limit, if the supplied resistor was fitted.

Quad knew exactly what they we doing - unlike all the geriatric ****ing
morons here.

Like YOU !!!

You might care to explain why Quad modified the way this voltage limiting
for the ESL worked on the 405, then, if it were perfect from the start.

Peter Walker hated them all.

He had a great respect for the BBC engineers ...


** Like hell he did.

Shame he is not around to tell you how ****ing WRONG you are.

FYI - Tony.

I must admit I had *no idea* just how ****ing out of touch with reality
you were until now.

Believe whatever you like,cos there is no hope whatever for utter
****wits like you.


Couldn't agree more Tony. I met him and had a chat when he and his wife
were demonstrating the new ESL63 at the hi-fi show


** Claiming the famous Peter Walker would *agree* with some of the
worst audiophool tripe imaginable is ****ING DESPICABLE !!!!!!!



Nope.. he was a very open minded gent and did spend quite some time at
Broadcasting house where some of this products notably electrostatic
speakers were used for quality evaluation..

Tony Sayer should be taken out and whipped for doing it.

Read the thread here,

1. Sayer claimed the Quad 405 had flawed sound.

It does have its shortcomings .. No amp is that piece of wire with gain
like peter said, and he knew that...

2. He produced a quote from some audiophool at the BBC to back him up.


Yes some audiophool BBC engineers and studio managers who of course
haven't the faintest idea of what actual sound should be like, after all
they have those studios full of orchestras and all.. I mean how could
they have any idea at all;?..


3. Then he claimed Peter Walker would agree.

Which he did..

Ever meet an other Audiophool Rupert Neve at all?. Worked with this
Audiophool once. I suppose if ever there was one he'd be one of
course..


Is that not the worst sort of crazy, false arguing you ever saw ?


.... Phil

** Indeed it is**

BTW ever met Russ Andrews?, now thats an worse then audiophool if ever
there was one;!..

You seem to be fixated on 'audiofool' stuff to the point where
you think
nothing can be improved after it's left the factory. But
haven't
explained just why so many modifications were made to the 405
by 'the
factory' over the years of its production, and not explained
by
components becoming obsolete. Quad themselves offered upgraded
boards at
one point.

Indeed. more generally it was routine for Quad to modify the
circuits and
issue new versions of the boards, use different components,
etc. The 34
preamp is a classic example of how much the innerds changed
with time as
well as the externals.

I've always regarded this as being a sensible approach which
others also
used. Armstrong Audio always described it as 'continuous
development'. Let
the maker keep tweaking and improving the performance and
reliability in
the light of experience and the arrival of preferable
components.

That said it may sometimes go too far. I had the feeling that
Jim Sugden
and Arthur Radford could hardly make more than one or two units
with
exactly the same details! Always tweaking and experimenting.
8-]

At the other end of the spectrum the mass-market Japanese makes
could often
decide change model totally every year or two. But then they
often made
their own components, as well as having more R&D engineers than
most UK
makers had employees in total!



That is where Julian Richer made his pile. The Orientals, be they
Jap, Korean, or whatever, produce a new product, a year later
they give it a facelift but otherwise rarely make any changes,
then two years later they bring out either a completely new
product or an upgraded model. Usually there was very little
difference especially at the facelift stage, but the
manufacturers wanted people to buy the 'latest' version and sold
off the 'old' version to people like Richer.
