As for the cable length, consider an awkward load that drops to 2ohm

resistance should not exceed 0.1ohm.

Then get some decent speakers.

Apogees drop to 2 Ohms, apparently. Don't you regard them as decent?

Do you?

Yes.

Do you use them for monitoring?

If not, please state why not.

The company went into bankcruptcy seven years ago.
No service, no spares - so no good for professional

Oh - and you appear to love valve amps.

Yes. We do have a couple of Radfords, but a much
larger number of SS amps, Crown, Amcron, Carver,
JEC etc etc.

Describe which one you use to
drive them ;-)

We use B+W, JBL and Tannoy, all of which conform
to IEC/EN/BS EN 60268-5 and so can be driven
by any amplifier of sufficient power.

Hello Wally.

I like 'fader jockey', sorta goes with DJ remixing..... :-)

Makes me smile to think about a DJ remix of my
current recording project: Dvorak Op.90. No.4 in E minor.
Know it, Stewart?

As well as you do - possibly better.

I doubt it:-)

However, I always thought that
the E minor key was rather dumb..........

What does that mean?

Oh dear - whoooooosh..............

Piano Trio No4 in E minor, Opus 90, is also known as the Dumky.

Which has nothing whatsoever to do with the Czech words
"nemy" or "pitomy". Languages not your forte, Stewart.?

The term comes from a Russian/Ukranian classical form.
I will be pleased to discuss it with you, though perhaps
this forum is not the best place to do it.

Cordially,

Iain

No - it is still behaving as a transmission line - it has no choice. It is
just that the characteristics are changed. And of course in the case of the
CAT5 speaker cable, parallelling them up effectively drops the corner
frequency. This corner frequency is a network effect.

Are you sure that parallelling cables reduces the transmission line
corner frequency?
Can't see it myself but I'd be happy to be proved wrong.


Nevertheless true. How close together physically would you want the common
conductors to be before you would be happy to agree that the frequency
would drop?

Let's start with far enough apart that you aren't changing the properties
of the individual cables.

They are carrying identical fields, so there is no significant interaction.

You (and Churches) also missed the obvious retort to the snide
slipping in of 'nemy' and 'pitomy' in his post above. He's a snide and
arrogant clown, but none too smart.................

Smart enough not to have to be a postman:-)

I guess you don't have the knowledge to discuss
classical trio form then?

Why would I need it? It's an irrelevance to *audio*. I guess he
doesn't have the knowledge to discuss active device transfer curves
then?

I wonder judging by your transistor amp design posted on RAT
if you do? Not one person, including your goodself bothered to
build/evaluate it.

But, unlike you I don't set myself up as an expert on areas in
which I have little or no knowledge. Your posts re disc-cutting,
equalised masters, helium, large condenser mics,
and now DASH are doing the rounds:-)

Not in an *audio* newsgroup, certainly. There are dozens of music
newsgroups in which such matters can be discussed to your heart's
content. They bear no relation whatever to the quality of reproduced
sound in the home, which is my interest.



I am however curious about one thing. We know that Finland has one of
the highest suicide rates in the world,

Yes caused to a great extent by SAD (Seasonal Affective Disorder), a
lack of sunlight during the winter months, and does affect people here
in the UK, and yes people have been known to take their own lives
because of the resulting depressive state..

but I wonder if this was true
*before* you moved there........................ :-)

Don't you think that was a bit uncalled for Stewart?.....

The one valid reason I know to roll your own is to make something that
sits nice and flat under a carpet. The commercial offerings all seem to
be horribly expensive. I have in the past made a speaker cable from two
layers of self adhesive copper tape either side of some polythene. Even
under a very thin mat, they couldn't be felt.

Being lazy I'd tend to use the 'flat' cables from someone like Maplin.
However the construction you describe is potentally a very good one from
the POV of having very low series inductance. (The snag being high shunt
capacitance, making it unsuitable for some amps - which I would not use
anyway! :-) )

Slainte,

Caveat noted. For real cables - particularly those of speaker ilk
which have very low resistance (we can effectively ignore the
conductance of the insulator, but if it is finite it does tend to
offset and cancel the copper resistance effect) the characteristic
impedance doesn't rise significantly until you are below a few hundred
Hz. Above this frequency the normal equation applies well.

Looking at some specs, A typical QED cable has a characteristic
impedance of 109 ohms and a corner frequency of 4.6KHz. CAT5 has a
corner frequency of 50kHz, below which it doesn't behave as a TL.

'Transmission Line' is the method of analysis. The cable could still be
regarded as a TL, but just one whose properties are significantly
dispersive. However there is little point in treating such 'short' runs as
TLs when a lumped analysis will do as well in such situations.

Slainte,

Jim

I have been here half my life, and know no one who has anyone
in their immediate circle who has taken this sad step.

When taken in context, and compared with the numbers of deaths
caused by smoking, heart disease and traffic accidents, and skin
cancer in countries with strong UV one starts to get a more

Don't worry. That's SP's "humour" (he even used a smiley:-)

Yet despite him explaining this on more than one occasion at least one
'subjective' journalist kept describing what PJW was saying in terms of
turning it into "all amps sound the same" versus "all amps sound
different". FWIW the journalist in question was unable to show he could
hear a difference in tests set up by PJW to were carried out in the kind of
conditions he specified.


Yes well, Jurno's have to eat and sell magazines who have to attract
advertisers, and after that what can you expect?.

As well as stir up some controversy to further sell their printed
wares......

On the other hand, it is of course trivially easy to find two cables that
sound completely different; but that isn't what the debate is about.

It was originally. My original posting stated that Audio Innovations
Silver cable sounded noticably better than Gale XL105 (which is a very
good budget cable).

When challenged, I referred to an experiment I did some years ago where
I was sat behind a friend's system and swapped between a freebie
interconnect and a £10 Cambridge Atlantic. Blind test, as he couldn't
see what I was doing and which cable was connected. The result - 100% of
the time he told me correctly which cable was in use.

And I'm told by another friend who's been reading this thread that
Pinkerton's reply was something along the lines of "bulls**t". Although
he also mentioned that Pinkerton has persisted in posting replies to me
after the inevitable *plonk* that he received, at least for this thread.
Clearly the guy doesn't even realise he's been killfiled... or more
likely is so retarded that he doesn't understand what it means.
