I have never been interested in cables. I've always figured Radio Shack Gold
were good enough for me. However, a friend of mine recently did a quick
switch of XLO and Tara RSC Decade. One of these brands (which?) is an open
twisted pair construction, encapsulated in something that looks like Kapton.
The other is a conventional coaxial construction.
There was an obvious difference. The open-twisted pair wires were much
brighter than the coax.
I speculate this is due to both low capacitance, and reduced skin effect.
Unfortunately, these were very expensive cables. Do any reasonable cables
have similar characteristics?

Probably that means that they in some sense broke your
system, Bob.
Tell me Bob, why you love to parade accusations about my bad
science, why aren't you doing some scientific measurements
of your own to get some technical understanding of what's
going on here?

Speculation is free, but relevant technical tests can be
done at a relatively low cost.

Construction of home brew twisted-pair interconnects is a
simple study in soldering. Or is soldering too much high
Science for you, Bob?

Quite so. As you yourself have observed, what Arnii wallows in is a very bad
substitute for science. Like everything else related to Turdborg, his Borgma is
redolent of feces. I heard that a big part of the Hivie induction rituals is
eating a big **** sandwich. Not a big deal for the Krooborg, who routinely
indulges his coprophilia, but quite an obstacle for the young "trainees" ;-) he
recruits from Sunday school.

**I still use some of the cables from these guys:
http://www.apature.com/accusound_chart.asp
when they were imported into Australia. They were very reasonably priced and
very good performers. I've performed a large number of blind tests and am
satisfied that they make a difference, compared to budget cables. In some
instances, clients do not like that difference. I suggest the silver, or
silver plated cables will suit your needs. I have no idea what their cost is
in the US. My only reservation was the construction quality of the
soldering. This may or may not be an issue in 2005.

For theoretical reasons, copper seems a better choice.
The higher the conductivity of the material, the greater the skin effect.
Hence, silver would cause the greatest reduction in high frequency response,
rather contrary to what I'm after.

For a given diameter, conductors made of material with low bulk conductivity
have less skin effect than those made of high conductivity material. Thus it
is actually possible that conductive plastic cables would offer improvement.
As far as I am aware, there are only four reasonable possibilities for
signal cable differences:
1. inductance
2. capacitance
3. skin effect
4. dielectric memory
Of these, the first two can be compensated for by tone controls,
equalization, or the like, because they comprise a distributed linear filter
in the cable.
The last two, however, are nonlinear effects, which means that the
degradation they cause the signal, if any, cannot be reversed.
There is an elementary exercise every physics student does in adv.
undergraduate and again in graduate electrodynamics. It's a homework
problem, found in the chapter assignments: to compute epsilon, the depth of
the "skin", at various frequencies, for a particular bulk conductivity. The
answer is, it is very significant in the high treble (> 10 kHz region.)
Paradoxically, the lower the conductivity, the greater the skin depth. The
implication is that what one definitely does NOT want is a conductor with
very high conductivity, because it excludes AC.
The phenomenon of superconductivity is more interesting still. A
superconductor EXCLUDES all time-varying fields. This is a direct result of
the above skin effect calculation: epsilon goes to infinity. If one attempts
to impose a time varying field, with an arbitrary potential, the
superconductor quenches, ie., transitions to a state of normal conductivity.

**I am aware of skin effect and the complex calculations required to
quantify the effect. However, there are a few things worth knowing:
* Skin depth at 20kHz is bloody close to 0.5mm. All conductors in the
Apature cables I use, are 1mm diameter.
* I still don't believe that skin effect has any relevance at the impedances
use in line level interconnects.

**And again, with 1mm diamter conductors and audio frequencies, it is all
acedemic.

Robbert "bad scientist" Morein opined:

Agreed.

I'm sorry, but your assertion is not well grounded.
Two aspects of the above statement are subject to dispute:
1. There is no trivial mathematical basis for it.
2. It may still be true, but there are no publications that support it. The
publications of Malcolm Hawksford go against the above statement.
If the poster wishes to claim point "1", the below serves as a refutation:
The skin depth is defined as the depth at which the conductivty is reduced
to 1/e from the surface value. e ~ 2.718
The formula varies depending upon the material. Assuming copper, the skin
depth sigma is given by sigma = 2.6*K1/sqrt(f).
At 10 kHz, the skin depth is .026 inches = .664 millimeters.
HOWEVER, the factor of note, 1/e, is an artifact of the equation that
determines skin depth. For audibility, it is more relevant to consider the
attentuation in dB, if the attenuated cross section were driving an ohmic
load.
The magnitude of the derivative (which is negative) of the conductivity
curve, is greatest at the boundary. The loss in conductivity of one factor
of 1.3, is approximately equal to 0.664mm/4 = .166mm at 10 kHz.

George,
One can never be sure. However, as a fellow literati, you are probably
more conscious of literary style than anyone here, save one person who, I
think, would prefer to remain unnamed.
The style of the post is not Bwian's. Although a reasonably versatile
mind might be expected to have the capability to emulate a variety of
styles, Bwian has never shown that ability. Several of us have communicated
with his sockpuppets, and, indeed, they have been the subject of lunchtime
discussion by law enforcement. As far as we know (note disclaimer), Brian
has never exhibited the ability to transparently emulate the style of
others. In the past several weeks, he has appeared on this group in several
guises, but I haven't bothered to point it out.

Here are the corrections to Hawksford's errors:
http://www.audioholics.com/FAQs/silversmithaudiocables2.php
which references:
http://db.audioasylum.com/cgi/m.mpl?forum=cables&n=63636&highlight=malcolm+hawksford

http://db.audioasylum.com/cgi/m.mpl?forum=prophead&n=1373&highlight=hawksford
and adds:
"The Hawksford analysis, as printed in the Essex Echo,
neglects to include the storage of energy within the
conductor...the 15 nHenry per foot number with copper. This
is a result of the treatment of the wires as conductors
whose voltage and current arise as a consequence of external
fields. This is not the case for current carrying
conductors. In addition, Hawksford neglected to test
various guages of copper wire conductors, instead,
substituted a steel conductor with a mu of approximately
100. Since the internal inductance is proportional to mu,
the actual inductance he did not accout for was 1.5
microhenries per foot per wire, or 3 microhenries for the
pair. On the assumption he used a meter of wire, that is
about 10 microhenries unaccounted for in his simulation, and
hence, the inductive overshoot in his test. Clearly, had he
modelled this inductance, with the loop resistance of his
wire, he would have found that the wire matches the formula
for inductance provided us by Termen in 1947."

Ironic, isn't it that Morein hoots and hollars so often

Ironic does not really fit, this case, this seems much more a case of
outright ignorance.
So much of what he says is simply wrong, the fact that he is not aware
of how idiotic he is might be ironic, if weren't so pitiful.
Mostly, Morein seems to be so desparate for people to play with, that
he chooses this place and tries so hard to be one of the "Normals,"
shows how pitiful he is.

Inductive & capacitive effect of speaker cable (in uncoiled, reasonable
lengths anyway) at audio frequencies is just about zero. You can measure
the stuff if you don't believe me. Skin effect is simply irrelevent. If
you were shoving 1000A through it and trying to keep the weight down then,
yeah, take it into account, but as the cable, speaker and amp output
impedences are all working together to keep the current well below this
and weight isn't a problem then just forget it. Leave it where it belongs
in the power distribution business.
The biggest differences (if any!) in speaker cables are found during
sighted or badly-conducted comparisons. What does this tell you? I
speculate that your cable comparison is null & void if you can hear any
difference - or you broke something. The resistance of the connections
will be lower when you connect a newly-stripped length of cable but that
is a difference in *connection resistance* that you hear - not in cable.

Mick,
What is the skin depth for copper, at 10 kHz ?
What is the depth for the current density to drop by a factor of 0.7?

Depends who you believe - a number of qualified independent
sources, or an old-timer who was obviously working out of
his element.

Wrong question. The right question is: "Where is the science
and reliable listening tests that show that skin effect is a
significant problem".

agreed with the comment "There is no audible skin effect in the frequency

As a matter of interest, what would be the effect of using TV aerail co-ax
for line-level audio connections for distances up to say 50 metres?
The cable is widely available, cheap, well-screened, and has a solid
conductor. It works well at high frequencies, but what about the 20-20kHz
range?

Hey Arnie, howzit going?

What I can't understand is why you are bothered. You, no doubt, are using
a good quality connector at each end (if not then you should be!). You are
interested in making contact with *all* the strands that make up the wire
if possible, as that will give the lowest overall resistance.
What happens to the current between the two end connectors is almost
immaterial providing you don't lose too much of it or push it through
something too non-linear. You can't control it anyway.
The only time it is of any consequence is when you are sizing a power
conductor for minimum losses and that is only really important in
distribution switchgear where it makes a hell of a difference in conductor
costs. We sometimes use copper-coated aluminium - Cuponal - for busbars as
most of the current flows in the copper skin and the weight and cost of
the bars is kept down. This stuff doesn't really start to pay for itself
until you get up to CSAs like 1.5sq in running at about 75% load.
Worrying about skin effect is a pointless exercise in speaker cable as I
pointed out previously - the inherrent loop resistance will swamp any
changes due to skin effect. Please, if you really want to mess with this
then do some *measurements* - not listening tests. You will find them far
more revealing.

Dunno about your tv coax, but the cheap stuff isn't well screened at all.
It doesn't need to be at UHF, so manufacturers leave big holes in the
screen layer that would make a difference at AF.

Yes, zounds. Not there's anything wrong with that. I just like the sound of
my cables better. Go figure. I have been always been quite neutral, but
braided regular Radio Shack copper sounds better to me. (when branded as
kimber does) Even on cheap systems. This was a few years ago. I have since
got some Grados and Bringers for reference. Simply pristene sound. But I
know there is something missing, and I also know that I will have the
hardware to extract this missing detail in the future. However I have good
enough ears to tell that I am hearing pretty good sound right now. Beringer
rocks in the area that they are in- nearfield monitors, and they play
wonderful music for me. bass, good spread, good response. I get the feeling
that I'm hearing everything, given my 30 years or4 so in listening to music.
Don't get me wrong!
I say that a lot, but it rings true. I know how stuff is supposed to sound.
This is like cooking. Getting the right temperature and ingredients all at
the right time. I know how making sound work can be a hassle. It's all about
what tit sounds like to you. Forgive me for belaboring a point that has been
bandied about ad-museum, but this is about how music sounds- to me and to
you. There's no middle ground- there is only how this tune sounds to you.
Make it good for you.

**Wrong and wrong. Cheap stuff is usually well shielded (nowadays). The
standard (over here) uses a 100% aluminium shield, with a braided copper
wire overlay. The better quality stuff (still VERY inexpensive) uses two
layers of each. I pay AUS$0.365c/Metre for the cheap stuff and
AUS$0.60c/Metre for the good (US manufactured) stuff. Moreover, at audio
frequencies, the shielding via even twisted pair is OK, unless the signal
levels are very low (i.e.: phono), the impedances very high (i.e.: tube
sources) or the site very high in interference signals. I do certainly
acknowledge that it is good engineering practice to use a well shielded
cable in all situations, however. Additionally, there are a couple of
problems with using TV coax for audio:
* The centre conductor is usually copper plated steel
* Often the shielding is all aluminium and can be a PITA to solder to.

Interesting... Your "cheap stuff" sounds a lot like our "satellite" cable,
with al foil screening. You'll rarely find that used for tv aerial
connections on this side of the globe. The screen, in most cases, is an
open weave (probably about 75% coverage) of rather fine copper (or some
sort of copper alloy). The inner can be either solid (usually used for
outdoor installations) or stranded (for indoor connections). Both screen
and inners solder well. Insulation can be solid, but is usually
semi-air-spaced - i.e. a cross-section of the insulation looks like 7
polythene rings arranged in a circle, touching each other, with the
conductor running down a solid bit in the centre. This coax is very
lightweight.
So, not wrong in the UK, but we are looking at different tv systems! :-)

Robert "bad scientist" Morein said: "The corrections are doubtful."
Actually, what's doubtful, is your understanding. You seem to have
many problems in that area, starting with college and on into your
stunted adulthood. Below is a tidbit I found on another group.
Originally posted by Dangerdave on rec.audio.tubes:
For very high frequencies, those where the AC impedance of a wire
becomes significantly higher than DC wire resistance due to skin
effect, the resulting "high frequency wire resistance" is given by
Terman's method:
R = 83.2 * (root (f)) x 10-9
______________
d
This form of the equation applies to cylindrical copper wire.
Where;
R = ohms/centimeter
d = wire diameter in mils
f= Hertz
When "high frequency wire resistance" rises to a value equivalent to
circuit input impedance, the response of the circuit will fall by -3dB
due to wire skin effect.
Therefore, it is useful to know at what frequencies wire skin effect
becomes important when employing hook-up wire in audio frequency
circuits. For some commonly used gauges of hook- up wire, I present
the frequencies where wire skin effect becomes important (-3dB point)
using Terman's method.
For 10cm lengths of copper wire the -3dB frequency is given by:
f=((Rin*d) / (10 * 83.2 * 10E-9)) quantity squared
Table 1
18 Gauge Copper Wire (40.3 mils diameter, 10cm length)
Circuit Input Impedance -3dB point due to wire skin effect
10 Ohm 234,619,140,625,000 Hz
1k Ohm 2,344,619,140,622,500,000 Hz
Table 2
22 Gauge Copper Wire (25.4 mils diameter, 10cm length)
Circuit Input Impedance -3dB point due to wire skin effect
10 Ohm 93,201,044,748,200 Hz
1k Ohm 932,010,447,482,000,000 Hz
Table 3
26 Gauge Copper Wire (16 mils diameter, 10cm length)
Circuit Input Impedance -3dB point due to wire skin effect
10 Ohm 36,982,248,520,800 Hz
1k Ohm 369,822,485,208,000,000 Hz
Table 4 0.13cm dia wire silver wire (5.1mils dia., 10cm length)
Circuit Impedance -3dB point due to wire skin effect
1k Ohm 3,757,4542,344,700,000 Hz
By simple inspection of results it is clear that skin effect plays no
role in audio frequency circuits interconnected with 10cm lengths of
hook-up wire. The frequencies involved, TRILLIONS of Hertz or more,
do not exist in audio circuits (except as noise). To put things in
perspective, the highest frequency humans can hear is 20 THOUSAND
Hertz.
For circuits of higher input impedance, skin effect becomes even less
important.
Interestingly, application of Terman's method demonstrates that tiny
gauge wire (Table 4) is about 100x worse for skin effect, as compared
to normal gauge hook-up wire. The reason is simple. Bigger wires
have a larger circumference. Skin effect crowds current to the edges
of the conductor. By Terman's method, when the circumference is
larger, there is more material conducting current. If you want to
reduce the impedance of hook-up wire in your audio frequency circuits,
choose a larger diameter.
Using silver makes no difference. With silver or copper, skin effect
play no role in audio frequency circuits interconnected with hook-up
wire.
An RF rule of thumb is that skin effect becomes important when the
wavelength approaches the diameter of the wire. I think it is a good
rule of thumb, however, some have taken issue because it may produce
results that are "many orders of magnitude" in error. Correction
noted. By application of Terman's method it is clear that the minimum
frequency for skin effect in audio circuits is not BILLIONS of Hertz,
it is, more precisely TRILLIONS of Hertz, or more.
Inductance, capacitance and resistance of hook-up wire is millions of
times more important than skin effect to the sound and electrical
response of audio circuits. To improve your audio circuit, use normal
gauge hook-up wire, and pay attention to routing and placement.

OK, just sit there waiting for my call. Or I might knock at your door, if

McKelvy, your inability to see my flagrant sarcasm notwithstanding:
1. Anyone who claims that plugging an alarm clock into the wall results in
the smoothing of electrons and overall improvement in the quality of sound
reproduction is illiterate.
2. Anyone who claims that wire (or as rocket scientist Boon says 'cable')
can be uni-directional, needs to take Electrical Engineering 101.
3. Anyone who claims that upsampling a PCM encoded redbook from 44kHZ to
192kHz needs to study Nyqvist's Frequency Theorem, write a paper and hope to
either get the Nobel prize in physics or themselves committed.
4. Anyone who claims that speakers with a frequency response of up to 35kHz
are great, because the supersonic 'interactions' improve the overall sound
needs to have their heads examined, and perhaps invest in a box of Q-tips.

It's true that Maggie's hatred for me is quite obvious.
"Her" comments about the wife and pets have to be

So it's your position that there's absolutely nothing wrong with you, and you're
perfect and wonderful and truthful and respectful of others? And no criticism of
you is ever justified by your own behavior, and every rotten thing you do or say
is excusable because somebody, somewhere, at some time, did or said something
similar to you?
Help us understand the Kroo's-eye view of the world, Arnii. Lord knows it's an

When I volunteered to help families suffering from domestic abuse a couple
of years back, that very thought was one of the standard responses offered
by the perpetrators. Interesting...

That perceived "normalcy" was also standard among the perpetrators. Every
perpetrator seemed to know someone who was a lot "worse". The plot
thickens...

Arnii,
It looks like you did not take my advice and go outside.
"everybody who observes this well-known fact is automatically a
convicted spouse *and*
pet abuser?"
The above makes absolutely no sense. But then again, enraged people seldom
do. Go outside now, Arnyi!

Jeez, multiple responses to a single post. I guess that in your burning rage
you just had to hit the send button before your brain came up with an insult
or two. You simply lost control, Arny. It is interesting how single-minded
your insults always are - surely an indication that there's more than a
resemblance to Mr. Dahmer. Luckily there are shelters these days...

**Why bother? Gainclones just use the same output chips that cheap, mini
stereo systems use. They're OK, as far as it goes. However, they tend to
have poor current ability and don't really offer anything special.

I'm under the impression that this chip family is based on a
chip that was originally designed for a US electronics
manufacturer, perhaps Bose.
The gainclone is cheap and easy to build, ideal for homebrew active
monitors, garage or **** pad systems, or what have you. I don't call
them serious audio but considering a good junkboxer can build a pair
for almost nothing they are handy to have around.

All cables have a sound. the best have very little. Wake up.

I don't know why you even bother. I'm listening to Metallica. And it is
good.

**Handy for what? Making noise? Amps which will do what Gainclones do are a
Dime a dozen. There is no need to even warm up the soldering iron.

Well, I've not built one ... my wife has the curious idea that we have
enough amplifiers already.
However, the LM3875 for example has an unusually high PSRR; I do wonder how
it achieves that. The only idea I came up with is that it's using current
feedback rather than voltage feedback. And if that were the case, its ouput
would be relatively unaffected by frequency-dependent speaker impedance
variation ... so you'd get a flatter frequency response from a single driver
powered by an LM3875 than from a typical high-end amplifier..
Listening results would then depend on the speakers used; on a high-end
speaker with complex crossover embedding impedance compensation, the LM3875
would sound worse than other amplifiers; but on a speaker with a simple
crossover, it would sound better.
This is all speculation of course.

LOL! Your wife and mine must belong to the same club or society!
