Here ya go darlin's - knock yerselves out on these speaker cables:

Siltech Signature G6 - only £30,000 a pair......

Find 'em on http://www.siltechcables.com/nfhomepa.html

Noise floor of 180 dB - how can they *not* be worth the money?

Beats the crap out of that 79 strand 70p/m unbranded ****e you lot
use.......

(Dave Whitter's already got a pair on order... :-)

I especially like this description they give in their digital
interconnects bit...

"All digital signals are, in fact, analogue.

True.

A digital signal is a square wave,

False. These guys obviously never looked at a SP/DIF signal with a 'scope.

which consists of sine waves, all with much high
frequencies. These sine waves added together reproduce the square
wave. If one of these sine waves is missing because of, for example,
reduced bandwidth, the square wave becomes distorted and subsequently
timing errors may occur."

Rounding of digital signals does not in and of itself lead to timing errors.
There needs to be some source of nose as well. Furthermore, various means
for eliminating the effects of probable timing errors on digital signals are
well-known.

Heheheheheh, so digital is actually analogue eh?

On several levels...

However digital-domain audio signals have several properties that
analog-domain signals lack:

(1) digital-domain audio signals can be readily transmitted, and stored with
zero linear and nonlinear distortion.

(2) The residual noise in digital-domain audio signals can be reduced until
it is arbitrarily small by fairly simple means.

In short, perfect sound forever!

"Perfect Sound Forever" was Pavement's first EP.

With digital hifi/radio/tv you'll normally get either a perfect feed or
nothing. There is a /little/ space imbetween with video formats robust
enough to loose the odd byte to pixellation, or error correction

Consider analogue tv, where quality is roughly proportional to signal
strength, but with digital you either get it or you don't. It's like that
with digital hifi, if you are getting any signal at all its likely perfect
already and no amount of silver wire can improve it.

It really bothers me sometimes when people pay this much to be fed techno-
superstition. Maybe it's because anyone THAT dumb is unlikely to have
earned the money.

My thoughts exactly, no cable, no matter how cheap it is (within reason)
should be disrupting a digital signal, even though it is an analogue signal
in essence the quality of the signal should not effect the sound - digital
signals have a readable threshold much lower than analogue, low signals
below this threshold should not occur on any distance shorter than say, 10m.
Interruptions of square waves only occur in cable runs which have such a
high resistance and the source is producing such a low voltage that the
signal is attenuated dramatically before arriving at the destination.
Usually the source transmitter or the destination receiver is at fault in
digital audio, either for low signals or _very_ bad error correction - NOT
the connecting cable.

Right here I have an 80m run of cheap cat5. That works fine at 100
megabits per second with £4 network cards!

Digital signals genarally do not use 'square' waves, their signal is
added to a carrier wave. [1]

For example, a sine wave may be used to carry the signal. While the wave
is 'in phase' could stand for binary zero, while 180° out of phase could
be binary one. In the real world it is likely more than two phases will
be used, eight states used to be comon, to represent 3 bits at a time.
The advantage of this is that several different signals can be
transmitted at once, using different frequencies, which is the basis of
broadband comunication.

Consider analogue tv, where quality is roughly proportional to signal
strength, but with digital you either get it or you don't. It's like
that with digital hifi, if you are getting any signal at all its
likely perfect already and no amount of silver wire can improve it.

[1] This technique is not exclusive to digital transmision, normal FM
radio is done by applying Frequency Modulation to a carrier wave, AM is
amplitude modulation. If the signal were digital phase modulation is most
likely used.
