This works because the marketing for expensive cables is effective and
a lot of people that buy expensive audio equipment do not have a grasp
of the basics they were taught at school or, perhaps, they do not trust
that knowledge in the face of the marketing.

The audio publications go along with it because they earn their living
from advertisers and not the consumer. If they were to become a voice
of reason they would soon become a magazine that few advertisers using
audiophile beliefs as part of their marketing would want to use and, I
am afraid, few audiophiles would want to read because audiophiles want
to believe. Such publications would go bust or disappear into obscurity
and stop being an effective voice of reason which is why they are no
longer around.

You get the responses you do on these pages generally from old fogeys
who developed an interest in audio a few decades ago before the boom
ended and when a larger proportion of audio equipment was significantly
differentiable on performance grounds. The establishment in the late
70s and subsequent growth of the audiophile sector within audio has
largely driven out people with a technical interest but a few still
hang out in odd places like this.

If I go cheap is it better to bi-wire? most of the on-line reviews I
have read say bi-wiring is the best way to go, I am now very confuzzed.

No. Biwring using reasonable cables will not create an audible
difference to the sound impinging on your ears in normal circumstances.
Some may perceive a difference though under uncontrolled conditions
and, depending on exactly what pleasure they derive from the cables, it
might even be money well spent for them. For most it will not.

No, it's nothing to do with resistance, it to do with the fact that
each speaker can be moving at different speeds and directions. From
this there is a chance that the woofer can send distortion up the
cable and interfere with the tweeter frequencies.

Are you talking about back EMF from one driver affecting the signal going to
the other driver? (Presumably, that from the bass driver is of greater
concern due to it being rather higher power.)


You use a thick
cable to the LF to send raw power. The tweeter needs a cleaner
signal, so you use a thinner cable for that.

Do you mean that you *need* to use a thinner cable to get a cleaner signal?


By connecting the cables
at source, and separating them at the speaker, there is enough time
to prevent the interference.

In a single-run cable, how long does it take for the interference to affect
the other driver? And what happens to the interference in a bi-wired set up?
(Where does it go if it isn't going into the other driver, I mean.)


On a proper bi-wirable speaker, you actually feed the crossover points
separately, so the signals don't actually mix. If you bridge the
connections, you turn it into an ordinary speaker.

Yeah, that's what my speakers have - four binding posts with little metal
straps.

Not sure I understand your question! Are you testing me, or do you not
understand the principle of biwiring?

The principle appears to be that bridging the terminals at the
amplifier sounds different than bridging them at the speaker. I
suppose you MIGHT be able to construct cables that distort the signal
so much that this is true. But why do that?

No, I'm being too charitable. It's bull****.

Why does a dog lick its ********? Because it can.


Reminds me of the story of the Hooray Henry at a smart dinner party - he
watched as the dog suddenly lifted a leg and started furiously licking its
balls. The HH said 'Oh, I say - that's rather clever, I wish I could do
that!!

The somewhat bored hostess said 'If you gave him a biscuit first, I'm sure
he'd let you......'

Yes, that's exactly it.

Anyway, that's the last I'm saying on the matter. It's obvious that many
can't tell somebody they think they're wrong without being insulting
about it. No wonder they say conversation is dead.

I'f I'd said the same thing to any of them face to face, I'll bet their
responses would have been different. I don't mind if I'm wrong, but
please tell me I'm wrong, and *why* you think I am, in a more
constructive way. As it is, the people that don't know, still don't know
any better.

Andy, if you'd just said something wrong, anybody here would have been
happy to set you straight. Sadly you didn't do that - you just stood
in full view and dribbled down your chin. It was frankly embarrassing,
and you needed shutting up before you embarrassed us further. So no,
don't come over all wounded; if you know absolutely nothing (apart
from utter ********, that is) about a subject, just keep quiet and
nobody will ever know. Lesson learned?
