Vividly; it's not been extinct that long. Google finds very many leads
including various versions of the picture. HMV Retail still exists, as does
Virgin EMI Records.

Yes.  In the '50's, I attended such a demo by
Ampex and the San Francisco Symphony at the SF War
Memorial Opera House.  I was on the main floor
about 2/3 back from the stage.  I couldn't tell
the difference.  Midway through the opening
overture, the orchestra put down their instruments
and walked offstage, but the music kept playing.

Interchannel phase differences *measurably* alter the stereo image. Phase
difference between voltage and current has no effect unless a non-minimum
phase device is involved.

'Live versus recorded' demos (with good results) date way back to the early
1950s, first in USA and soon after in Britain.

Re: [PSES] Fuses can affect performance other than safety!

[Ken Javor]

A very simple and inexpensive means of arranging staging is to introduce
delays between left and right channels such that the sound appears to be
coming from a particular direction. This is much easier to accomplish with
headphones than loudspeakers, but it's the same principle.  I've seen a
convincing demonstration at the US Army Aeromedical Research Lab (USAARL),
where something like five different radios can be going at once and a
helicopter crew have to be able to intelligently respond in a crisis
situation, and what people normally do in a situation like that where they
can't pay attention to everyone is they zero in on one conversation and
ignore the others, and to do that we use directionality. Originally there
was none and the headphones could be blaring all channels at once, and the
crew would simply turn off he radios they didn't want to hear, which wasn't
good. By introducing specific delays for each radio, the various radios
could be made to sound as if one conversation was from 12:00, another at
3:00 another at 6:00 and so on. That allowed the crew to mentally focus in
on the conversation of interest and tune out the others temporarily.  But
that is all software and digital circuitry: no fancy audiophile equipment
necessary.

Re: [PSES] Fuses can affect performance other than safety!

[Peter Tarver]

I have heard of and known a few audiophiles that go to great lengths to have 
sound reproduced as accurately as possible and spend enormous sums to 
accomplish that.

The term that was most silly in my view was holography; but I understood what 
was meant. The aforementioned audiophiles claim to recreate the spatial 
relationship between the physical locations musical instruments when recorded. 
The needs for recording and reproduction are entirely impractical and don't 
seem achievable for simple stereophonics, so it seems on the bovine 
scatological side of the olfactory sense.

BUT, I have stood in and moved about a room that was carefully put together. In 
one part of the room one instrument (say clarinet) could be heard more 
distinctly than in other areas, and so on for other instruments, giving the 
impression that one was moving from musician to musician on a sound stage.

Pretty clever, but outlandishly expensive.

Since a number of years between tests I "rinse" coaxial cables with clean

Make sure that the dirty left-over current resulting from this action is not

I love this stuff.

Back when Monster Cable was making their claims, I realized that these people 
are actually very smart, they have found a way to make a direct connection 
between your emotions and your wallet.  At that time I conceived the idea of a 
company called Kabel Doktor.  The premise was, 

"All cables deteriorate over time, it is an unavoidable fact of life.  Annually 
you need to send your cables to the Kabel Doktor for proper cleaning and full 
spectral degaussing at the sub-atomic level so as to eliminate any surface 
charge carriers that may have built up as a result of cable skin effect.  These 
stray carriers result in constricting audio energy flowing down the length of 
your cables by effectively reducing the cross-sectional conduction area.  As 
part of our degaussing process, we provide charted analysis of the before & 
after spectral transfer characteristics of your cable, so you can now have the 
confidence you need for a full audio listening experience.  Our basic service 
will test your cables from DC to 300 kHz, for an extra fee our top specialists, 
using high-end spectrum analyzers, will use our proprietary process to test on 
the other side of the DC frequency barrier.  This will ensure that your 
negative curvature imaginary frequencies are also!
  part of your listening experience. Never be embarrassed again when you have 
friends over and want to play your latest full spectrum symphonic audio 
selections."

Only, I just couldn't bring myself to do it.

the return polices are generous.

Re: [PSES] Fuses can affect performance other than safety!

[B Rowland]

Wow!

It's a real disaster, then, that our VNA cables lack those arrows that show the 
preferred 'directionality' of the copper grains…and, how could we have done 
without the so-important to-distortion 'Di-electric Bias System', that, 
according to Audioquest:
"creates a strong, stable electrostatic field that saturates and 
polarizes (organizes)
 the molecules of the insulation. This dramatically minimizes nonlinear 
time delays 
and reduces dielectric-induced smearing of the signal"

I guess it goes to show that HP(Agilent/Keysight), R and Anritsu just don't 
know anything about signal purity….

Live and learn!

Re: [PSES] Fuses can affect performance other than safety!

[Ken Javor]

BTW, back in the early Œ90s I ran across an ad for a power cord that
replaced those that come with an audio amplifier. The 6¹ power cord cost
$600 US.  I was intrigued or perhaps a better description is the same sort
of morbid curiosity expressed in the subject thread, and I called the
company, and got the chief engineer/designer/CEO and janitor.

I very respectfully asked him to explain the benefits of this power cord,
and he launched into the pitch. The pitch was that audio covers a wide band
of frequencies, and all those frequencies come from the ac mains, and that
therefore a matched transmission line (his power cord) was needed to ensure
that all those frequencies made it from the mains into the music without
reflections and mismatch inherent in cheap power cords.  I asked two
questions. The first was what about the mains wiring in the home or
business, and he assured me that was already well-matched, so no worries.
The second question was the more obvious; that the ac mains are a single
frequency and that the audio frequency current to the loudspeakers comes
from the charge stored in the large filter caps and routed to the speakers
by the changing impedance of the amplifier's output stage transistors.

At this point he got mad and I had to reassure him I was truly interested in
the product and how it worked and wasn¹t just baiting him.  My curiosity had
foiled the intent of the ad copy to filter people like me out. I was just
wasting his time.

Conversation: [PSES] Fuses can affect performance other than safety!
Subject: Re: [PSES] Fuses can affect performance other than safety!

In the USA anyway, there is no need for a lawyer to review marketing claims
that aren¹t health-related and are not obviously factual.  You can¹t say the
Fiat 500C is faster than a Shelby Mustang,  but you can go on forever about
the wonderful driving experience. As long as it can¹t be quantified, there
is a quite a bit of poetic license allowed in advertising.

Next, the terms are not entirely gibberish. They may be unfamiliar to those
not in the hi-fi hobby, but I can make out all but one of these terms:

Sound staging means stereo separation.  Or whatever passes fro that in the
age of five and six different channels (I haven¹t kept up with this stuff
since it departed from two channels).  I don't know how a fuse aids or
degrades channel separation, but at least we can understand what is being
claimed.

Resolution means how clear the sound is.  How real does a particular
instrument sound? I find that on my ancient Martin-Logan electrostatic
speakers, that violins sound much better than on cheap systems. I think
(emphasize think) it may be because of the lack of a crossover network and a
flatter response across all the frequencies that make up a violin¹s
spectrum.  How is that affected by a fuse? I don't know that.

³Air² is the term I don¹t understand. I¹m guessing that if I were interested
and motivated, I could puzzle it out looking at a few audio blogs or
websites.

Noise floor is obvious and ³blacker backgrounds² means the same thing; these
are redundant terms with the latter based on a TV picture, where black is
the total absence of any signal.  Again, no clue how a fuse can increase or
decrease audio background noise.

This sort of product where the marketing totally drives the demand is
intentionally designed to appeal not to objective criteria that can be
verified by measurement but rather to allow the consumer to feel superior
because he can experience something the hoi poloi (that would be us) are too
coarse to see/hear/feel/experience.  You can write ad copy like this because
people want to believe it.  And you aren't selling to engineers. In fact ad
copy like this functions as the same sort of filter as does the Nigerian
businessman who needs to off-load boatloads of money on complete strangers
living in the First World.  If you have trouble with this ad copy, you
aren't going to shop for their products, and you aren't going to waste their
time asking your peasant-mentality questions.

Their time is more properly reserved for the people with finer tastes and
appreciation of the finer things in life, and who coincidentally have money
to indulge their desire to impress themselves and others as the connoisseurs
they are.

And don¹t bother telling the emperor he is naked.  It¹s not appreciated.

Re: [PSES] Fuses can affect performance other than safety!

[John Woodgate]

It is a contrived experiment to 'prove' a point by using impractical 
parameters. The fuse current rating needs to be so low that its element nearly 
but not quite fails. And it needs a low thermal capacity so it heats and cools 
quickly. 
 
I'm certainly not trying to justify the SRQF claims.

Not yet having read your article (tomorrow morning hopefully), I would then 
pose the question: since loudspeakers vary enormously in design and 
manufacture, then might it mean that a fuse which might work “well” for one 
amplifier/speaker combo might not work for another combo (maybe even the same 
amp and a different speaker)?

That doesn't work, either. Maybe they fell foul of UK Trading Standards and

Like many of these fairy tales, there is a grain of truth. If you put a

Thanks – I’ll take a good look at the paper you posted 
(http://www.jmwa.demon.co.uk/Introduction%20to%20current-drive%20audio%20amplifiers%20Rev.%201.pdf)
 , but whether I will understand it is entirely another matter L (that’s me and 
my intellectual limitations, not the article which I am sure is a well-reasoned 
approach to the subject)!

OK, anyone have any ideas on what “effects” changing a fuse to one of those

[John Woodgate]

That doesn't work, either. Maybe they fell foul of UK Trading Standards and 
won't send their web pages to UK addresses.
 
Like many of these fairy tales, there is a grain of truth. If you put a 
carefully-chosen fuse in series with a  loudspeaker, you can measure 
intermodulation distortion in the voice-coil current due to the element 
changing its resistance with temperature.
