As for Arny, I read every one of his literal-minded misunderstandings
in the hope of learning something. I wasted my time. The kicker is in
Arny's remark that:

If NASA listened to Jute, the Rusians would have beaten us
to the moon.

Arny is welcome to listen to Russian hi-fi, hundred per cent negative
feedback, total silence on an airless surface, if he believes that
suits the closed-circuit aridity of his mind.

I'll stick to hi-fi which plays music.

Yeah, I know, Arny. As should be clear from the text even to an
illiterate engineer, I wasn't the one who made the silly 50dB
suggestion; your accolyte Stewart Pinkerton came up with it; that is
why I told Pinkothicko to **** off back to you and stop pretending he

The Ultrafidelista view of Negative Feedback

by Andre Jute

Negative feedback is the paradigm of modern electronic
design. It is mother's milk to an electronics engineer.
He learns to say '100dB of NFB,' in his sleep before he
finishes his first week at the most humble polytechnic.

Good example of Jute's ignorance of the engineering
education process. Feedback is usually taught as it relates
to automatic control systems. Last time I looked courses
like these generally fit into the junior or senior years.

In short the idea that "He learns to say '100dB of NFB in
his sleep before he
finishes his first week at the most humble polytechnic" is
sheerist BS.

Before I even finished the design of the KISS 300B it was
forcefully suggested by a wannabe guru that with only
50dB more gain (about seven times as much as is likely to
be in the actual design) I can apply 50dB of negative
feedback to linearize my amplifier.

Good example of Jute's ignorance of feedback. It's highly
unlikely that one could apply 50 dB loop feedback to a power
amp with an output transformer and still have acceptable
stability.

Negative feedback, shorthanded as NFB, is the instant
response of the audio engineering fraternity to all ills,
real, perceived, non-existent. They don't even ask if
there is a problem, they swing the club of NFB
regardless. NFB has become a reflex axiom of mainstream
audio design. An audio engineer with his negative
feedback is like a policeman who runs out into the street
with his stick and starts beating a confession out of the
first housewife he sees. The difference is that the
policeman is relieved of duty to await punishment and the
audio engineer gets away with it. In the case of the
policeman it is unacceptable behaviour, in the case of
the audio engineer so much the expected norm that no one
except the ultrafidelista notice. I guess that if one in
ten million audio amplifiers does not have negative
feedback added, it will be a lot...

No amount of rediculous posturing can counter the fact that
NFB can be made to work very well and to great advantage,
thank you.

No one asked if my KISS Amp requires linearization. The
presumption by all except those already of the
ultrafidelista persuasion was that I would welcome
suggestions about A Good Thing.

If the kiss amp has less than 0.05% nonlinear distortion
with any power level or any frequency or combination of
frequencies 20-20 KHz, then its fine as is. I doubt it is
that good.

In the face of such overwhelming acceptance by qualified
engineers, why do we as ultrafidelista not take the same
easy path of negative feedback? Especially considering
that superficially NFB is easy to understand and apply.

How does negative feedback work?

Negative feedback is simply a negative voltage fed back
from the output to the input amplifying device to offset
part of the harmonic distortion which is present as a
positive voltage.

This is a highly incomplete explanation. In fact the voltage
fed back offsets not only the distortion but a goodly part
of the basic signal. Therefore, NFB generally reduces an
amplifier's gain for both the basic amplfied signal and also
the distortion.

It costs nothing except a loss of gain
and a few side effects such as phase shift and possible
instability which are well known in the mathematical
literature and more or less easily guarded against
depending on the level of NFB.

In fact NFB properly applied reduces, not increases an
amplifier's phase shift.

'Wow!' those meeting NFB for the first time will now say,
'Something for free! I'll grab some of that for my amp.'

Just just contrdicted the first phrase in the previous
paragraph that says that NFB has a price in the form of a
loss of gain.

Hey, I said it, and I am a professional intellectual, by
definition an infinite skeptic. NFB is a thing of beauty
that will draw you in. It is like an electronic Marxism
which admits of no contrary arguments because it has
subsumed them all into The Holy Measurements. To question
The Measurements is to commit heresy.

Jute's mistake here is that its not heresy to question
measurements, and people have been doing that for decades,
even in such conservative journals as the JAES.

You need to be of
strong mind to resist the blandishments of such a
universal panacea and of strong stomach to withstand the
hysterical assaults of the lesser engineers defending
their holy grail. (And when you do get hold of a superior
engineer to explain NFB to you, you need to be high-domed
indeed because suddenly NFB can turn very intricate.)

It is true that some advanced course work in calculus can be
of great help when designing systems with feedback. This
automatically disqualifies a great percentage of basement
geniuses and high end chief engineers, writers and
reviewers.

Unfortunately NFB doesn't come without a price. It levies
a cruel charge on the perceived quality of the sound.
Negative feedback is what gives all those 'blameless'
transistor and big PP tube amps their chillingly
unnatural sound.

Strange that these supposedly unnatural-sounding amplifiers
can pass a straight wire bypass test, and so many low-NFB
power amps can't.

Then how did NFB come to be such a panacea in amplifier
design?

Because when applied with reasonable care by competent
engineers, NFB works. NFB got men to the moon. NFB makes
your car idle and run. NFB keeps your water heater from
exploding. It keeps your house and oven at the temperature
you set on your thermostat. NFB makes cell phones work.
etc., etc.

Your guess is as good as mine. Hi-fi design is not
prestige work for engineers, or highly paid. The most
talented and best qualified engineers go into automobiles
or military hardware or big construction projects or
computer design.

All areas where NFB is highly depended on, and it works.

The left-overs design amplifiers in the
time they have to spare from writing up specs for
requesting a CE mark for a new electric kettle. Lemmings
storming en masse over a cliff come to mind; such people
don't see the necessity of original thought, or have the
mental equipment for it. The exceptions to this rule are
normally audio enthusiasts in charge of their own small
audio manufactories with niche markets; those who grow
larger from this base follow the mainstream mantra of
"mo' NFB give lowa' THD" because the marketing channels
demand it from them if they wish to grow. At this point
they usually cease to offer anything different, only the
exclusivity of a very high price. (I know, because a
sub-board I designed for a supplier to the trade turns up
in so many very expensive amps with so many different big
names neatly silkscreened on it... it strikes me as the
sort of detail a real designer, as distinct from a
marketer, would take under his own control.) Those very
few makers who will sell you an ultrafi amp without any
NFB operate even tinier shops, usually one man and a cat,
just hanging on.

Usually the cat knows as much if not more about calculus
than the man,

The mechanism by which NFB wrecks your sound

NFB wrecks the sound the same way NFB makes your water
heater explode: as a rule it doesn't.

Negative feedback at first acquaintance sounds good
enough to take to bed and cuddle. It isn't. It isn't even
as simple as a superficial acquaintance may suggest.
Follow the steps with me, from the theory as she is
received to what arrives at your brain as music:

1. In theory NFB reduces all harmonic distortion equally,
without discrimination.

Nope. NFB is often dependent on frequency. As a rule it
reduces higher harmonics less.

Strictly in theory it does not
reshape harmonic distortion by reducing the most
objectionable third and higher order odd harmonic
distortion to a greater extent than the relatively
harmless 2nd harmonic.

Actually, any order of nonlinear distortion, even Jute's
beloved order 2 can wreck the sound of music.

Thus NFB at its theoretically most
benign is already useless in terms of psychoacoustics, as
will become clear at point 4. If you disregard
psychoacoustics, as many audio engineers do, NFB is
brilliant in reducing total harmonic distortion to a
number as tiny as you want. You just pile on more NFB.

This paragraph really says nothing.

2. In real life, as distinct from simplified theory, NFB
adds artifacts of its own. Remember, it is a loop. The
signal starts at the input and is amplified by devices
until it reaches the output. From the output a part of
the signal called the negative feedback is fed back to
the input. Here a loop is completed and the combination,
less distorted, reaches the output again, a part of the
combination is fed back, endlessly. The artifacts we want
to consider here are created by the fed-back residue of
harmonic distortions adding to both the fundamental and
the distortions already created by the amplifier, then
some portion of the sum of the original and the feedback
distortion is fed back again and added on, until the
ooh-ah bird flies up its own fundament. It looks
marginally less disgusting as a recursive mathematical
formula with lots of nested parenthetical parcels of
noise being loaded onto your music.

This is for all practical purposes, total BS. The bottom
line is that a power amp with a properly designed NFB loop
has far lower distortion of all relevant orders because of
the NFB.

But it is a monkey on
the back of your sound, with a smaller monkey on the back
of the first monkey, a still smaller monkey on the back
of the second monkey, and so on ad infinitum. These
additive artifacts are all higher harmonics and the more
dominant ones are all odd. Suppose, for the sake of
simplicity, a superbly designed ultrafidelista amp with
some second harmonic and zero odd harmonics before NFB.
Add NFB and the second harmonic will be lowered but the
recombinant new loop now contains newly added
intermodulation effects between the fundamental and the
residual second harmonic, and that is third harmonic. In
the next cycle a small but nasty dose of fifth harmonic
that wasn't there before is added by interaction between
the still residual second harmonic and reduced newly
added third harmonic.

This is for all practical purposes, total BS. The bottom
line is that a power amp with a properly designed NFB loop
has far lower distortion of all relevant orders because of
the NFB.

In short, the artifacts NFB adds to
the distortion mix are all of the most harmful kind. But,
say the proponents of NFB, so what? Every time the loop
cycles the added artifacts are smaller, even if there are
more of them... The whole affair starts to smell of
trying to argue with a Marxist who simply declares any
inconvenient truth 'an anomaly'. (If this sounds like a
mess from which you should run a mile, you have come to
the right conclusion. Start running now. It gets worse.)

This is for all practical purposes, total BS. The bottom
line is that a power amp with a properly designed NFB loop
has far lower distortion of all relevant orders because of
the NFB.


3. We thus arrive at a situation where distortion has
been lowered by NFB but where the most disturbing odd
harmonic distortions are still present to some measure,
with the added disadvantage that new and extremely
disturbing artifacts of higher harmonic distortions have
been created by the very process of using negative
feedback to lower distortion.

This is for all practical purposes, total BS. The bottom
line is that a power amp with a properly designed NFB loop
has far lower distortion of all relevant orders because of
the NFB.


Regardless of the absolute
level of THD, or the volume setting, the mix of harmonics
has been adversely affected and now includes a higher
proportion of third and higher harmonics than before NFB.
Let me say that again: after NFB, third and higher
harmonics will make up a greater part of the distortion
than before.

But, all orders of distortion will be greatly reduced.

4. Low volume levels perforce accounts for 99 per cent of
audiophile listening because we all have families or
neighbours, and we would like to keep our ears.
Unfortunately for the lowest common denominator of hi-fi
designer, the one who specifies NFB as a conditioned
response much like Pavlov's dogs slavered when the bell
rang, human physiology and psycho-acoustic response is
such that odd harmonics are disproportionately more
disturbing at lower than at higher listening levels. This
inescapable effect is independent of definition of
'listening level.' At the 110dB in-room SPL (only 14dB
louder than an automatic riveter!) advocated by the
already deaf Transient Overload Elite known on newsgroups
as the Borg, this poisonous concoction of original
distortions and NFB recombinant artifacts will be least
disturbing (and soon not heard at all!). At any lower
level perceived interference of this harmonics cocktail
with the music will increase in inverse proportion to the
volume level. At low volume levels the artifacts
generated by NFB will by their nature as higher harmonic
distortions be disproportionately far more disturbing. At
these normal listening levels 0.75 per cent of second
harmonic distortion may be below the threshhold of
perception for sophisticated listeners, whereas tiny
amounts of third and higher odd harmonic distortions
grate.

NFB reduces distortion at all output levels, large or small.

And they still use Negative Feedback? Are they stupid?

No, they are wise.

No, they are not stupid. Most of them march to the drum
of a cost accountant on whom we wouldn't spit if he were
alight. NFB is as cheap in money terms as it is expensive
in terms of perceived quality of music. We shall come to
those who claim to be sympathetic to high-fidelity but
insist on devices which do not work without NFB, who have
another devious answer. Here, meanwhile, for you to keep
in mind, is a single-sentence summary of a complicated
interdisciplinary argument:

The case against NFB is that for 99 per cent of listening
the NFB cure is worse than the disease.

In fact the inverse is true.

But surely we don't have to do anything so stupid?

What's really stupid is avoiding NFB because of Jute's
senseless claims.

It follows from the argument above that ultrafidelista
should choose an intrinsically linear topology and device
which does not require added negative feedback to
'linearize' the output.

In fact good designs with NFB start out with circuits that
have as low distortion as is practical before the addition
of NFB. See Self's blameless power amp circuit for many
examples of this.

The intrinsically linear device
is the thermionic tube in either its triode form or as a
pentode hogtied to work as a triode, which can be a most
pleasing alternative both economically and sonically.

In fact triodes have built-in NFB.

The
topology is often single-ended operation, chosen also for
several other reasons described elsewhere in these
articles, including KISS; if the chosen topology is
push-pull operation, which is more difficult but far from
impossible to arrange without NFB, operation should be
specified as Class A1. Inside the argued case above lies
too the overwhelming reason to accept the potential small
disadvantage that may accompany the preferred topology in
comparison to the discarded alternatives. The
disadvantage is of course the potential for a residual
second harmonic that measures high by transistor or NFB
tube standards. (Note the word potential. With a
conservatively designed DHT amp the potential problem
should not arise.)

Push-pull operation is in fact a great way to make power
amps more linear prior to the application of feedback.

The ultrafidelista, who are as keen on silent amps as
anyone else, accept this small potential difficulty
because it is the lesser evil compared to NFB.
Unbelievers (largely unwashed, according to reports)
sneer that ultrafidelista like this approach because of
the 'added euphonics', which is bow-wow techie talk for
the warmth a big chunk of second harmonic lays on a zero
negative feedback single-ended amplifier. But competent
design can easily reduce the level of second harmonic to
below the level of perception without the need for NFB
and its deleterious after-effects. In any event, it is
your amplifier. You paid for it. You have a right to tune
it as you please. The key thing is to get rid of NFB and
to understand why you did it.

If you did it because of Jute's posturing, you're an old
kind of fool.

Can we prove any of this scientifically?

Hard to do because Jute's so-called scientific claims are
bogus.

We have already.

LOL!

All of this is the technical subtext to
my longtime contention that what the ultrafidelista hear
and love is not a directly heated triode sound as is
claimed by many enthusiasts but a Class A1, ZNFB sound.
(Admittedly, as we have seen above, the right sound is
virtually guaranteed with a ZNFB DHT SE amp of
conservative provenance but may have to be developed the
hard way with more economical or higher-power
contenders.) In comparative ABX tests conducted over a
number of years, I found that professional musicians,
certified golden ears, choose the triode-linked Class A1
PP ZNFB EL34 whenever it is present in the test over all
other contenders including SE 300B and 'blameless'
high-NFB silicon.

Show us your level-controlled, bias-controlled listening
tests, Andre.

Science also proceeds by pure reason.

Actually, science proceedes by both pure reasoning and
practical experience.


Ultrafidelista have
long doubted whether what engineers insist we measure
(the absolute level of distortion, THD) predicts success
in audio gear. This is the full circle, because I have
just proven by logical, individually uncontested steps
that what matters, once a certain modest level of silence
is assured to an amplifier, is not the absolute level of
disharmonics but their composition. The same proof
demonstrates that a more beneficial distribution follows
instantly from doing without NFB.


NFB lowers all relevant forms of distortion. Distortion is
one of those things where less is more.


But transistor amps won't work at all without NFB!

Absolute BS. Transistor amps without NFB were built in the
early days, before the refinements that enable the use of
NFB are possible.

That is not our problem. Those who choose inefficient
speakers and consequently are forced to accept monstrous
amps made possible only by gigadeciBels of NFB, will
receive our sympathy - and the music they deserve.

Seneseless posturing.

Engineering hangers-on of transistor attempts at high
fidelity, where the measure of success is vanishing THD
rather than sonic hedonism, pretend to be enthusiasts for
NFB. To make it work for them, they have attempted to
change the rules so that we won't hear what their
treasured NFB does to our sound. They sneer that low
level listening, which 99 per cent of us prefer and where
NFB does most to wreck the sound, is 'easy listening' and
therefore not permissible. According to them we should
all be forced to listen at the high volume level which
suits NFB amps, which they call 'realistic'. This is a
contemptible circular argument, only too characteristic
of a fascist mentality in a part of the audiophile
spectrum which wants to prescribe their arid vision
without regard for our enjoyment.

More senseless posturing.

We can recommend a good tailor to them. It hurts every
time you wear his suit. No pain, no gain, fellers!



In summary

Almost everyone listens at low level most of the time.

And, SS high feedback amps are what they use as a rule.

NFB wrecks everybody's sound at all levels but most
wretchedly at normal listening levels.

Wrong. NFB can work well at both low and high levels.

e started out
with a contemptible circular argument and we have met
another along the way. We can now put both in context:



An 'engineer' who designs an amplifier which does not
work perfectly without negative feedback is like a tailor
cutting the suit incompetently and then demanding that
you walk like a cripple to make it fit, so that everyone
can admire the brilliance of your tailor.

The joke is that Jute prizes triodes, which are just
pentodes with NFB added back in.


Negative feedback is a bodge. That is why it is
despicable to the ultrafidelista.

If NASA listened to Jute, the Rusians would have beaten us
to the moon.

I will give the same answer I gave regarding turntable design. How good an
amplifier is cannot be determined by looking at the feedback loop, or any
other single element of the design. The only valid test is how it sounds.

There seems to be some concern by hifi purists which is based on the
following:
1. The number of iterations within a feedback loop is infinite. How long is
the total transit time, through multiple interations, until inaudibility is
reached?
2. Feedback causes a relative increase in the proportion of higher
harmonics. There is no psychometric for this effect.

These two questions, which are, in fact interrelated, remain current because
amplifier measurement techniques are not sufficiently valid to predict how
an amplifier will sound. The only universally accepted fact seems to be the
established threshold of harmonic distortion. The regimes of amplifier
operation are a multivariate affair in the extreme.

I'm still waiting to hear Arny's statement on the status of his NAMBLA

A member "in bad standing" ?

DementoBorg has variously protested that it's a lie to say he is a member
of NAMBLA and a lie to say he's not a member. Perhaps you've identified the
curious Limbo-like state of Krooger's twilight existence: Neither real nor
unreal, neither factual nor fictional. Krooger is an un-being.

Can you explain how a triode based amp can be free of NFB?

This was my reply to Arny. Your comment is invited:

The above reply by Arny Krueger is garbage. There is no legitimate reason
to
draw from other fields to either justify or demonize negative feedback.
The
question under discussion is negative feedback applied to audio
amplifiers.
These nonsequitur references are trademarks of Arny's dirty debating
tactics.

I will give the same answer I gave regarding turntable design. How good
an
amplifier is cannot be determined by looking at the feedback loop, or any
other single element of the design. The only valid test is how it sounds.

There seems to be some concern by hifi purists which is based on the
following:
1. The number of iterations within a feedback loop is infinite. How long
is
the total transit time, through multiple interations, until inaudibility
is
reached?
2. Feedback causes a relative increase in the proportion of higher
harmonics. There is no psychometric for this effect.

These two questions, which are, in fact interrelated, remain current
because
amplifier measurement techniques are not sufficiently valid to predict
how
an amplifier will sound. The only universally accepted fact seems to be
the
established threshold of harmonic distortion. The regimes of amplifier
operation are a multivariate affair in the extreme.

You've misunderstood. No amplifier can be free of negative feedback.
There is negative feedback built into many devices, including Directly
Heated Triodes, the most linear devices known to audiophile man
(duck!). There is negative feedback inescapably inherent in many
goodsounding topologies popular with the ultrafidelista tube
fraternity. (The ultrafidelista love me as little for saying so as the
cramped, unimaginative wing of the cost engineers love me for pointing
out that their beloved NFB has a downside. Read the outraged tone of
Arny's comments. The less intelligent ultrafidelista when they abuse me
for consorting, as they see it, with cost engineers like Arny and
Pinkerton, who to them are Beelzebub.)

My case is that one should choose devices which require the least
additional, added, fat and sugar, high cholesterol, nasty, sound
artery-clogging, negative feedback. Any added NFB is bad, but loop
feedback is worse than local feedback.

HTH.

NFB used properly is not bad, used to much it can be.
It simply makes everything better when used properly.

The man has absolutely zero skill, knowledge, experience at anything to do

Ask Arny. He claimed in a post yesterday to have found the relevant
message. Or perhaps Arny is just lying for debating advantage as he so
often does. Or ask Pinkothicko, who claims to have been
misunderstood--maybe he looked up the message though that is hardly
likely because he continues to be caught out being slack about details
and lying a lot.

Certainly, it happened before I posted the KISS 123 article on NFB,
because it was the stupidity of Arny's monkey Pinkerton which inspired
me to post it. (PinkoThicko is the "wannabe guru" in the opening par of
the main piece. There is an intro with a relevant joke before that but
the humorless Brat Ludwig cut it, presumably because he believes that
no one on RAO has a sense of humor.) That site was put together from
about Sept 2004 forwards, so that must limit the scope of the search. A
search of RAT messages will certainly tell you when I first posted the
article because I would have announced it. Pinkerton's gross error, so
eloquently highlighted by the monkey's organ grinder, Arny Krueger,
must be before that date.

Unfortunately there are a lot of posts about that time, as Patrick
Turner was indulging his St Francis passion for salvaging lame vultures
and trying to teach poor Pinkothicko, who had challenged me to a design
contest, the basics of electronic design and making a ****ing awful
meal of it because Pinko isn't called Thicko for nothing.

I think you got it, Rudy. Lots of restful sleep will settle down
Oinkerton into something (possibly? nearly? approximately?)
recognizably human. Instead, every time I appear on RAT, poor old Pinko
sets his alarm an hour early in order to fire off rubber suckers. They
don't stick because I am entirely teflon-plated but Pinko has this
obsession with me that will not let him sleep.

I correct a few of Oinkerton's lies in this post in separate mails.

You mean like this bit: Quotation: assassins (of whom Pinkerton claims
Mr Jute was a member) to kill Mr
Jute was precisely for the books under the pseudonym Andrew McCoy
(according to Pinkerton "worthless potboilers"). Actually, it is


easy


Quotation: to find out that these novels were highly reviewed in the best
media
around the world. The New York Times called Atrocity Week 'a


towering


Quotation: landmark in the literature of violence'; the apartheid
government
agreed and sent assassins after Mr Jute.
More pathetic Walter Mitty stuff - if BOSS had tried to kill Jute,
they'd have succeeded, first time. And how pray, did this all become
public knowledge? Andrew McCoy is listed in the Fantasy section of a
literary website - and for good reason, as we see in these ever more
fantastical posts.

Or this one: Show me in *any* place on the face of this earth, a

two-stage amplifier with 300B output tube, designed and built by Andre

Jute. It doesn't exist, it's a myth spread by RAT's most notorious

liar and sociopath.


Or this one: Quotation:
The KISS Amp 300B project was temporarily halted because of
Pinkerton's
constant heckling and the tide of silicon **** he washed over
us, but
now that we have at long last seen the dumb 1960s cookbook
circuit he
put up as competition, I have been discussing in private mail
with
other RATs when precisely we should resume the KISS project.



Sure you have, Andy, sure you have. BTW, if KISS exists, why are you

having to 'resume the project'? Pathetic. BTW, your '60s cookbook'

comment is just hilariously, for someone who is supposed to be

'designing' an amp straight of a '20s cookbook...................



Really Stewart, how could be so utterly despiccable as to wonder how a
competed project could be restarted?

Has it ocurred to you, that along with your other childish behaviour,
mooning (I assume it means the same on the Jute home world as it does here)
is yet another pathetic and childish sort of response.

When you want to demonstrate your superiority, shouldn't you do that by
demonstrating it, rather than virtually sticking your past ass out of a
window?

Just a bit of advice.

Cordially,
Mike
