Church seems to shape up as a should-be-retired BS artist backed up
with obsolete audio knowlege and ancient test equipment. He's hardly
a threat to SP, let alone me.

Now what makes you think I have any intention of being a threat to
anyone. Your paragraph smacks of insecurity methinks.

So you set yourself even above SP?
Care to tell us of your pedigree Arny?

By audio rottweiler out of an ABX box. He has a very useful audio
website, but he's a royal US pain in the ass. I'd rather he wasn't
'helping' me................

I took a look at the Radford STA100 with THD
at 0.09% at full power, I could see traces of 3H, 5H, and 7H etc
but no even harmonics.

You wouldn't - because it's a push-pull amplifier. You'd see the same
spectral content - only bigger - if you disconnected the feedback
loop.

Thanks Stewart. First reply without an expletive:-)


Treasure it....

A true expert? Not from what we've seen so far...........

See earlier posts where Iain does not claim to be an expert. I
understand
he has a great deal more experience in that field than yourself.

Quite so. Experience does not equal expertise. See Tony Blair.....

That's about the most stupid remark I've seen all week.


Hmm, you can't be getting all his posts then....

(Lucky you - I've got him on the edge of the bin for no greater sin than
'bull**** overload' atm.... :-)

So why can't you behave politely on this ng - you say you can, so is it

you just don't give a damn for your own countrymen?


It's called 'arrogance' - a quality displayed by some people who aren't too
bright, despite a *possibly* extensive armoury of 'factoids' which may (or
may not) masquerade as 'knowledge'. (Certainly doesn't masquerade as
'wisdom'...) Frequently results in their rejection by their 'chosen field of
expertise' and has them scraping a living in places like 'Print Rooms'....



Usenet is international, and I respond as I find. UKRA used to be a
quite civil group, until the valves 'n vinyl clowns came crawling back
from the defunct UKRAV.


Ludicrous ******** as usual.....

..... and 'selectively' remembered: UKRA was so *not* 'civil' that the vinyl
group was mooted in the first place and, secondly, the 'valves 'n vinyl
clowns' never left this group. The vinyl group was intended to take out of
this group the 'contentiousness' that has got it the reputation it now has
(as a sewer) with a lot of 'audio enthusiast' who don't subscribe here or
who only lurk, not wishing to get involved in the proceedings.

(Can't say I blame 'em...)

What is most interesting is that the first to show up there were the
bigots - frightened that they were missing something....

LOL!

And I would prefer it if you would re-direct such requests to those who
more properly deserve them. I am not, nor have ever been, the worst
here for not snipping and, having explained my reasons, don't you think
your request would be better directed to the 'cause' rather than the
'effect'.....??

Not really, no.

Your postings have shown to me in the past that you are quite capable of
being polite and considerate. Yet on this occasion you gave as a 'reason'
for you failure to snip the fact that someone else failed to do so.

My personal view is that to improve the way people deal with one another we
should each try to be polite and considerate. *Particularly when your
reactions to one person affect other people as well.*

You may recall that only very recently I have snipped your *own *
responses one or two times when I've replied to you and which, IIRC,
contained previous content that you, in fact, could have snipped
yourself, no.....???

Yes, indeed. This is why I felt it was worth making my point as I believe
you are able to show the requisite consideration for others. However the
real point is that when you fail to snip one person's posting in a reply
you risk being impolite to (perhaps many) people other than that individual
who may wish to read what you say.

However: My apologies if my comment offended/irritated you.

Slainte,

Jim

Yes. I seems to be a problem in audio. As soon as there is an
"alternative technology" feelings start to run hot. I have a good
collection of CD's, a lot of vinyl both finished copies and test
pressings, and some 14 inch lacquers. I also have recordings on DAT, 15
ips quarter in stereo, and 35mm magnetic. Oh, and a pretty good
collection of 78's (mainly Duke Ellington) which I play on an HMV 102
wind up gramophone with trailer needles, as God intended.

Absolutely. I envy you your collection of unusual discs - I'm more into
tape. Can play/record pretty well any mono or stereo format ever -
including 8 track cartridges and Elcassette. No multi-track beyond 4,
though, - the machines are too large. ;-)

I play all of these, they all give me immense enjoyment, and I accept
the strengths and weeknesses of each format.

That's all that can be asked for.

I've got a cylindrical gramophone too. It gives as much pleasure simply
looking at it. ;-)

BTW, I use the RM parcel post a great deal (for a private user), and
find it *way* superior in every way to any of the independents.

I used to buy CD's from Tower Records in the UK.
So many were stolen in the post, and failed to arrived that they
now use a courier. Many component suppliers follow the same
line.

I can accept this happens in some areas, as it could be the individual
postman. Luckily, mine have always been super. I've never had anything
lost in either direction.

Had a computer disappear when using a courier. It was packed in a 'new'
expensive monitor box. I'd have loved to see the thief's face when he
found an Acorn Archie inside...

Took forever to get compensation, too, despite it being insured and of
modest value.

It is extremely nice. The posts are moderated, which is why you
wouldn't last
very long there.

I am in fact one of the most prolific posters in rec.audio.high-end,
another moderated group, so you're wrong again.

What's that got to do with RAT, twister??

English isn't your first language, is it?

Regrettably English may not be his last language, at least not yet.

Agreed. They even had Usenet give them URAV, which quickly died on the vine
because they couldn't stick it often enough to us mainstream guys over
there.

Since you claim you have a spectrum analyzer Iain, why haven't you
investigated this claim for yourself?

I have both the HP3580A andf 3581A. I took a look at the Radford STA100
with THD at 0.09% at full power, I could see traces of 3H, 5H, and 7H
etc but no even harmonics.

The effect of a PP and o/p transformer is, in many circuits, to reduce
some
orders of distortion but increase others. Hence what you see is probably
an
effect of the symmetry of the output arrangement. Any NFB will then (if
appropriately applied) tend to reduce the remaining nonlinearity.

Using 'symmetric' arrangements in SS designs has similar effects of
chaging
the odd and even components in different ways. But as with valve, this
comes from symmetry, not feedback.

You should be able to find descriptions in various texts. For example,
I checked this morning and it is in Deketh's "Fundamentals of Radio-Valve
Design" (Philips Tech Lib or reprinted by the Audio Amateur Press). In
my edition is it covered in section 96 (Ch XVII).

Slainte,

Jim

Thanks Jim,

I will ask at the library. I also have a copy of RDHB. I will take a look
in
there. Old dog, new tricks:-)
