I agree that in the case of a coupling capacitor the ideal design drops
a negligible *signal* voltage across it. The article and its test are
of dubious relevance there.

However, consider the case of a single-pole RC filter. In the pass-band
substantially the full signal voltage appears across the capacitor.

So I suspect there can be relevance in measuring capacitor non-linearity
with significant AC signal level. I am not sure if in a valve amplifier
this may happen inter-stage with the sort of signal level the article
uses for the test, though. As an input RC filter the signal voltage
across the capacitor will be somewhat smaller than that used.

But do remember that in a low pass filter, the opposite situation
applies. In the passband, the capacitor looks to all intents and
purposes like and open circuit, so it still doesn't matter what the
dielectric is doing. Now, at the top of the passband, where the
capacitor is starting to matter, some of this might happen, but at
that point the filtering action is going to attenuate any products. Of
course they will probably be outside the audio band as well.

Indeed. And may also in practice be orders of magnitude less significant

conditions of use.


This is certainly true of the linear effects of dielectric absorption
(DA). I see audio cable and capacitor sales literature pronouncing
that energy storage in DA and its later release "smears" transients.
Well, if it's a linear effect [1] it does cause ripples in the frequency
response so it may do what's stated. However the magnitude of the effect,
when I plug in some real numbers for DA, is several orders of magnitude
below what should be audible [2].

If there are audible differences between capacitors there's no evidence
yet that DA is the (or even a) culprit.

[1] The DA models are all linear, but I have searched occasionally
for any evidence of non-linear effects arising from DA. These may
be audible if big enough. However the one mention I found was for
semiconductor-insulator (e.g. Silicon - Silicon Nitride) boundaries but
it provided no details and no references to follow up.

[2] Based on reported levels of audibility arising from frequency response
differences. However, recently I have become interested in the human
sensitivity to audio arrival time differences. Detectable differences
as reported seem to be smaller than implied by 20 kHz hearing limits.
I am looking out for more evidence on this.

I'd agree. So bear in mind I'm not quibbling for the sake of trying to

we

people may use the same words or phrases in critically different ways.
With
that said, I'll continue... :-)



OK, you don't need to qualify your responses to me, but see below...



Put simply:


If someone jacks his kit up on cubes of coconut husk or whatever (don't
dismiss that as impossible, btw) and tells me it has *improved* the
sound, I say he perceives a difference (real or imagined) and therefore
believes there's an improvement. OTOH, in the time-honoured ukra way
(*unheard*) I would not believe it - unless I heard the kit before and
after and could perceive a difference myself?


Does that help?


Not sure. :-)

The problem is that some people might react to the statement that he
"perceives a difference" as meaning that he physically sensed a difference



Yes, that's how I would see it. (Perceive it? ;-)


- e.g if we could have attached some measurement kit to his ears it would
have produced a changed output. Others might take it to mean that his
impression was that there was a difference.



OK. This is where it hangs. If someone says he 'perceives' (can see,
discern, determine, tell &c.) a difference, then I take it that he is under
the impression there is a difference - effectively the same thing, IOW...


When you say "could perceive a difference myself" we have a similar
difficulty. I'd say that if a set of tests were done which could reliably
establish that - by sound alone - you/he repeatedly showed you could tell
the difference, then you did 'sense' or 'detect' a difference, but if such
tests showed no such result then you have 'believed' it.



Sure. The fact that someone says he perceives a difference in no way means
there is one. The proof of that pudding is in testing, as you say. Until
disproved, his belief is based on his apparent perception.



FWIW I'd agree that even 'belived' is difficult in such situations. Hence
my preference is to try and use language that is more based on
evidence-linked statments like those above. The snag is that these can get
long-winded, and may still be problematic....



OK, see below....



It is just that my impression is that I've seen many arguments which were
simply based on those involved not all using the same meaning for terms
like 'perceive'. Hence they argued at cross purposes, or in a way that was
futile. My interest then tends to be to ask what the nature and detail of
the evidence may be.



OK, see he

One of the reasons I am glad English (in its various forms) is becoming the
global language* (despite a tendancy toward homophony - which many
foreigners find difficult to master, apparently) is not so much because of
the exact precision possible with it (especially in the written form) or its
brevity compared with many other languages (record sleeves and multilingual
instruction manuals for example) but because of the high degree of
flexibility (and adaptability) it possesses. In the spoken form, 'fuzzy
English' is very often capable of transferring a clear and precise meaning
while appearing to sound like gibberish, if you catch my drift...?? ;-)

Thus I could flag down passing motorists (say) and get them to listen to a
couple of bits of kit and would be able to ask them if they could determine,
perceive, tell, see, hear, discern &c. any 'difference' between them or I
could ask if they could 'split them', 'pick one', 'rate them', grade them'
and so it goes on - all with much the same outcome. (FWIW, I have found that
if I ever phrased an instruction or question with precisely correct wording
it was invariably queried or I was asked to repeat it!!)

Now, you either get that or you don't!! (If you don't dig it, it's no skin
off my nose!! ;-)

While you are not wrong *per se* to persue a high degree of accuracy in the
words used by people to say that they can [any of the above] differences
between bits of kit, or before and after tweaks/substitutions I do think the
context in which the phrases are used should be be borne in mind.
Understanding the concept is more important than understanding the question
(sign language?) and provided that the word used/misused is generally
understood by all others concerned, I have no problem with the use of the
word 'perceive' in the context we have discussed here - for instance, I'm
often seeing the words 'religion/faith/belief' being confused and misused
here, but it does not matter because I can usually per***** the concept that
is being referenced!! ;-)


*The reason French was never going to make it as the true, long-term global
language (despite being favoured by the Royal Courts in Europe at one time
and being fairly, if thinly, widespread) is because a) There are official
movements to rigidly control the language and the use/meaning of words (from
what I gathered from a proggie on the box recently) and b) French women
don't shave their armpits. The world at large doesn't view either of these
practices favourably....

substantially the full signal voltage appears across the capacitor.


Yes. Three cases had occurred to me after continuing to think about this:

1) Something like a Baxandall arrangement when the tone was set well away
from 'flat' sic. Here quite noticable ac levels could appear across some
of the caps without being cancelled in effect by that on another cap.
Although in most control amps in my experience this would be or the order
of a volt or less - far less than the 70v RMs used in the page we were
discussing.

2) 'Miller' shunt caps between the base and collector (or equivalents for
other types of device) as used in some designs across the output devices.
Here the voltage swings seen by the caps could be almost 'rail to rail'.
Hence they could easily be 70v RMS in some cases. However the cap values
would normally be small, and within a loop, and shunted by the device
(whose own capacitance may be far more nonlinear!) I doubt anyone would be
using an electrolytic for this! I've never noticed such a design giving
noticable distortion from this, but it is something I would avoid applying
anyway, so have not investigated it.

3) The C of the series RC of a 'Zobel'. As (2) this could see rail-to-rail
ac. However this should be gripped fairly tightly by the output impedance
of the amp, so although it may ask the power amp to deliver a nonlinear
current through the Zobel, it should have little effect on the output as
seen by the loudspeakers.

There are other examples like the C of an input LP RC roll-off filter to
prevent an amp being driven into slewing. However in most cases like this
I'd expect the level of the ac to be well below 70v RMS.


So I suspect there can be relevance in measuring capacitor non-linearity
with significant AC signal level.


Yes. That was why I was asking in an earlier posting for some examples to
see if there were any. I haven't really encountered any that seem
comparable and relevant, but for all I know they may exist, e.g. in some
valve designs. The above all occurred to me as 'in principle' areas where
an effect might show, but in each case I've never seen/heard anything
significant as a result in practice.

I am not sure if in a valve amplifier this may happen inter-stage with
the sort of signal level the article uses for the test, though. As an
input RC filter the signal voltage across the capacitor will be somewhat
smaller than that used.


Yes. In a twin-rail amp using SS devices I tend to expect caps to only
appear in a few places like an input dc block, or the block on the feedback
to reduce the dc gain. In these places the ac levels seen in normal use
should be generally relatively tiny.

I'm familiar with nonlinear dielectric effects in terms of using bulk
material effects for things like frequency conversion in optonics devices
or Bragg cells. But the actual field levels and d/dt levels in such
applications tends to be high in order to get useful levels of
nonlinearity, and the materials chosen specifically for their nonlinear
properties.

I recall a colleague who used to build non-linear pulse lines for pulse
compression/peaking. He found some HV caps by a given maker that had truly
'awful' levels of dielectric nonlinearity when hit with multi-kV pulses.
His comment was that their slogan should be, "Don't take the **** out of
our capacitors: it spoils their usefulness!" ;- The point being that
most well-made caps simply didn't do this to such a level.

hearing limits. I am looking out for more evidence on this.


I'd also be interested in that. However it does not surprise me. The
sensors for a given frequency band may have response interactions whose
timings have nothing to do with the physical limitation of the ability of
the upper HF sensors to detect 20kHz. The processes are distinct, I assume.

FWIW I have a recollection of reading about the above somewhere. I think
there may be a reference to it in one of the papers I refer to in the
articles on hearing on my Audio Misc pages. Can't recall, though, as I did
that some years ago...

Good point. However even if the current in the capacitor is low, the
RC product and therefore the -3 dB point may be modulating with the
voltage amplitude. I will have to think if this effect is negligible.

The thing is, does this really matter? As well as context, we have the

Here's another view from Allen Wright (designs amps)

what the brand is - if they make a CP and a cermet (or even a quality

quality. The VISHAY cerment (made by their french wing Sfernice))
sounds. like two good fixed resistors, the identical looking CP sounds
like ****! Allen

Oh dear someone else who thinks resistors have a sound.

A pot, whether cermet, conductive plastic, carbon or whatever is a pure
resistance (discounting irrelevant tiny amounts of capacitance and
inductance- wirewound pots excepted) and consequently are linear to the
limits of measurement. Therefore how any pot can be better than another
for sonic qualities is beyond me. Pots vary in the accuracy of their
law, the noise made when being altered, tracking on stereo, how long
they last before track wear is evident etc. Sonic differences are just
not there.


The funny thing about this is that the referenced Mr Wright says he likes Vishay
Sfernice's cermet pot, yet Vishay Sfernice themselves promote the conductive
plastic version as better for audio. Nothing to do with 'having a sound' btw -
it's simply that cp pots have lower rotational noise ( they don't crackle when
turned ).

You might care to know that famous high-end UK recording console maker Neve uses
those very same cp pots that Mr Wright rejects.

I'll accept that pots, capacitors, resistors etc. sound different when I

show that there was a difference.


So is it not the case that metal film resistors have lower noise than carbon ones,


The difference is less than it used to be. Carbon film has simply got better.

and that this gives an audible and measurable difference in phono and microphone
preamps?


With regard to noise it *can*. It's a question of whether in any given circuit the
excess noise of a resistor plays a significant part in the overall total noise. Often,
resistor excess noise may not be the big issue. Poor quality resistors can also have
excessive popcorn/flicker noise. That applies to poor quality metal film as much as it
does to carbon too.

* Excess noise is the part of a resistor's noise that isn't accounted for by ordinary
thermal noise.

Note that this is a question, not a statement. I haven't measured anything recently.

Very, very true. A ridiculous way to make such a test.

I can find *no* difference whatever between the various plastic film dielectrics
in a real world application whatever using Audio Precision test gear.

The business about ceramics is very old news and it seems he didn't test the

I've only seen it with small value electrolytics as coupling caps at low
frequencies and very high signal levels with low load impedance on the load end
of the cap ( *where the voltage across the cap starts to become significant* ).
Even so, the numbers are quite low. Roughly from memory with 10uF and a signal of
10V rms @ 20Hz into a 600 ohm load it was somewhere around 0.03%. Reduce the
signal level to something more typical, increase the load R, increase the
frequency and most of all using a larger cap ( to a more sensible 100uF ) all
reduce the figure. In fact with 100uF I simply couldn't measure *anything* except
with very high signal levels @ 20 Hz and even then it was barely out of the test
set noise floor.

In more typical real world use even the electrolytics produce no measurable THD (
AP THD floor is 0.0008% or -102 dB )

have this sort of voltage, as will most driver valves. a 845 would have
a much higher voltage.


Utter rubbish. I suggest you measure *across* it.

The myth here is that Google results are unchanging.

The current number is "about 14,300". YMMV.

However, 10,000 or 100,000 aren't signfiicantly different in this context.
It's all "lots".

BTW thanks for distracting the discussion on a trivial point - that's known
as the proverbial "red herring" argument. I knew you couldn't do any better
than that - like try to stay relevant.

I think you were trying to point out to us all that your preferred
rationale was near-ubiquitous. My point that a google search showed that
1) it's relatively minor, and 2) context is important (IOW many of those
references could be critical).

So I at least was trying to get to the bottom of the basis of your
argument, rather than the outputs you generate.

properly, but they are amazing right from the off!!) My first 'custom'

of the price of the equivalent Fostex units. Get them from Neil at Impact

Yep.

Got nowt to do with it - you only pull the cable if you want to replace it -
see the fancy 'fat speaker cable' (pricey OFC stuff) here, for example*:

http://www.apah69.dsl.pipex.com/show/fatcable.JPG


It doesn't matter how the cable is connected to the driver - personally, I
can't be arsed with spades, I solder 'em and then I know they're
*connected*....

(I'm with Pinky on cables - they only need to be long enough** and fat
enough not to get hot, for me!! ;-)

Here's a shot of the terminal tray (speaker tipped forward) to set your mind
at rest - no extra chage for the 'sawdust coating'!!

I already tole you - how TF could you run it through this lot:

(the top is the far end in the pic) and be able to pull it after the cabinet
is built and sealed? (Forget tacking 'pull throughs' onto it - let's keep it
real!)

Terminal blocks/trays on these muthas just ain't done, believe me! - If I
had only the one (valve) amp on the go, I would run the wires right into it
and hook it directly to the trannies!!

Besides, it's a *horn* thing....

Easy! You could have put a couple of additional holes through the
internal baffles, and pulled it through right at the stage you were at
in the piccy.

And I'm sure there is plenty of room for the amp in the bottom of that
big speaker box - there's a new take on integrated speakers for you...

No, Alzheimers is definitely *bad* for the brain....

Right, here you are then:

A while back you asked for a recording from the driver level and the horn
mouth on the Pinkies - not easy as the horn mouth is on the rear, but the
new Faure horns exit at the front. So, with the mic positioned thusly:

http://www.apah69.dsl.pipex.com/show/driverposition.JPG

http://www.apah69.dsl.pipex.com/show/hornposition.JPG

I made the following (horrendous) recordings - 'normal', 'driver' and
'horn':

http://www.apah69.dsl.pipex.com/show/Normal.mp3

http://www.apah69.dsl.pipex.com/show/Driver.mp3

http://www.apah69.dsl.pipex.com/show/Horn.mp3

I know the level is too high on the 'close up' recordings. I know they clip.
I know they are lopsided, due to removing considerable DC Offset after they
were recorded clipping*!! I know all the bad ****....

(These extracts are for an *idea* - I ain't after Plowie's job...!! ;-)

(Not for fishmongers neither....!! ;-)

Yes, the speakers are raw and yes, they need hoovering out already - I see
the sawdust is starting to get through!! :-)

Enjoy. Comment. Breathe slow. Appreciate life for the *wonderful* gift it

Stick with the pertaters, Don - or you'll get Arny bitching about "red
herrings" :-)


Kippers to you, mate. And then only the nasty ones from supermarkets -
real ones have hardly any colour (thinking back to a trip to Arbroath
years ago).


Not to be pedantic about this, but I'm from Montrose, and an Arbroath
smokie is *not* a kipper. Kippers are herrings, an Arbroath smokie is
a haddock. To rotate back to a musical theme, essentially the same as
Peggy Lee called a 'fine Finnan Haddie', which hails originally from
Findon, further up the coast.

Nah, he likes valves and horns!

Was that a haddock? Bugger me - I've spent the last twenty years in a
state of confusion over me fish (and me a Faroe man and all!). Oh well
- so where do they make kippers, then?

'Veridical perception' - oxymoron.
Wrong.

Google finds upwards of 100,000 references to this
phrase.


Wrong.


different.

15,300 actually.....


The myth here is that Google results are unchanging.

The current number is "about 14,300". YMMV.

However, 10,000 or 100,000 aren't signfiicantly
different in this context. It's all "lots".


BTW thanks for distracting the discussion on a trivial
point - that's known as the proverbial "red herring"
argument. I knew you couldn't do any better than that -
like try to stay relevant.


I think you were trying to point out to us all that your
preferred rationale was near-ubiquitous.


It's not a rationale, its a reasonably common word phrase, given that it is
highly specific to the study of perception.

My point that a
google search showed that 1) it's relatively minor, and
2) context is important (IOW many of those references
could be critical).


Pardon me, but if that was truely your point, why did it take so much
prodding to get it out of you?

So I at least was trying to get to the bottom of the
basis of your argument, rather than the outputs you
generate.


No, you were trying to respond to a serious discussion with redicule.

End of discussion, on the grounds that casting pearls before swine is
generally not wise.
