Thanks for the info Stewart. I make 12 AWG to be about 3.3 sq mm,
which fits with my original rough calculation of (10 x
Rcable)(Rspeaker) for about 5 meters length. I may add some
temporary bi-wiring using some old single strand power cable I have.
Just out of curiosity :-)



Post your findings here when you have tried it.

(I have never noticed any difference with biwiring in the past....)

Willdo Keith. BTW, I have first sound from my IPL transmission lines....wow!

Many pics and other stuff on the construction when I get time...I have to go
earn a crust for now :-)

I'm aware of the never ending discussion on interconnects and speaker
cables, but I just want some advice on what to actually buy. Nominal
impedance of speakers is 6 ohms. Room is quite large and so
amp/speaker distance will be 4-5 meters. Speakers are bi-wired.

I just need an idea of cross-sectional area and where I can get some
suitable cable. I'm not convinced by the talk of OFC and so on.
Multistranded copper of sufficient thickness is fine by me.
Suggestions please ?

You should be aware that *all* multistrand cable is OFHCC (oxygen-free
high conductivity copper), because this confers the required
flexibility. Hence, OFC or OFHCC is jusyt a marketing label applied to
standard flexible copper cable. SAs to the rest, something like QED
72-strand or 105 strand will be more than adequate for your
requirement, and you can probably find the equivalent speaker wire
even cheaper at B&Q. Basically, aim for something like 12-14AWG
thickness if you can get hold of it.

BTW, bi-wiring does nothing whatever, so you're better running a
single run of thick cable and leaving the jumpers in place. If any
shop guy tells you that bi-wiring halves the cable resistance, ask him
what he thinks the crossover does, and check the blank expression on
his ignorant mug. Then buy somewhere else......

12 AWG (which is indeed about 3.3 sq mm) copper wire has a linear
resistance of approximately 1.6 milliohms per foot, giving you a loop
resistance of about 52 milliohms for a 5 metre cable. This should be
between 1 and 2 % of your minimum speaker impedance, so not a problem
by any measure.

Yes, most likely overkill, but a small amount of extra cash compared to the
overall cost of a system.

Gale XL-105, 69p/metre at Richer Sounds. Or if you need lots, you can
get the same stuff at CPC for about £20 for a 100m roll (different name
on it, same cable as far as I can tell).

Nice and flexible, doesn't sound bad either.

I googled on Gale XL-105 and one of the web sites said this:
------------------
However, it does have a rather raw quality with some programme material,
and there is a sense akin to stasis at times.
Music simply goes through the motions, but somehow nothing much seems to
happen, and imagery stays firmly locked into the speaker enclosures. It also
sounds rather grainy at times.
---------------------
Which was rather typical of most websites I visited, even Gales themselves.
Significantly, among all of the lurid prose few of the websites mention the
most important parameter, ohms/meter. And even if this is somewhat high on a
long wiring run, how could anybody possibly hear the "raw quality" described
?

I'm wondering if I should set up a business selling gold plated mains cables
with 13A plugs to the more gullible members of the hifi fraternity for
£99.99 a throw? Obviously, I would need to do a course on creative writing
first :-)

How about this then:
"Merlin powerblock....4-way power extension block...fitted with noise
absorbing system...elimination of stray emissions and prevent the degrading
of your hi-fi sound."

A snip at £145 each, P18, Wilmslow Audio catalogue.

Bummer, there goes my get rich quick plan.

Unless somebody wants to buy some extension power blocks from me, complete
with surge suppression and noise filtering. I can do them for £99.99 and
this isn't a wind-up, I really can offer these items.

There's some lovely phrases on that website:

"..featuring sophisticated circuitry for dealing with mains noise and
voltage spikes without limiting dynamic headroom."

"Traditional solutions would simply filter the mains supply to the products
attached, by using simple, but dynamically constricting filtration."

"...utilising Shiva, Vishnu, or Valhalla, prioritising the input cable
first; and by attaching Nordost Pulsar Points to the M6 threaded inserts in
the base of the unit to control any unwanted resonances the Thor offers an
unparalleled solution to advanced power distribution."

"Quantum QRT Resonance Technology is also used; this is a proprietary
material treatment system, which by the use of cutting edge technologies
minimises environmental electrical resonance noise."

Wonderful stuff :-)
