Fdeck - be careful on this topic, it's like religion!
I too work an engineering capacity (pro audio for TV)
and have tested some of the mythical claims for
these cables on such rigs as the Audio Precision
System One - not a whole lotta "there" there....
Most of the selling pitch of the "boutique" cable companies
is lifted from a completely different area of technical application
and has no basis in fact with regard to audio signals.
What may be big issue stuff in the gigahertz range (two inch waves)
made out to be like it matters in wavelengths of several miles(audio)
But the emotional logic is powerful - if it cost THAT MUCH
it HAS to be better
We carry multi million dollar signals on West Penn
and Beldin wire
Miles of it.
A good cable has : Flexability, durability, solid reinforcment
where the plug and cable meet, high shield weave density,
low capacitance, and stays quiet even while being worked
(moved around) . Avoid molded end stuff (in most cases)
Learn to make your own! get yourself some Mogami like
Mogami Quad Mic cable W 2534 for cheap and some
high quality Switchcraft or Nuetrik ends
You will have - custom length,
super quality - an endless supply
Canare StarQuad can be made into great instrument and patch
wire as well - you can get it all over. Read this blurb for
an expanation of what "quad wire" is about.

The claims at the Laboga site for their products seem on level
at least - not like some of these companies.
"Oxygen free" is another ambigous claim...
================================================== ======
Oddly enough, it isn't the freedom of oxygen in copper wire that makes any difference. The process of removing oxygen also removes the impurity of iron and it's this impurity that can cause the resistance to be slightly higher. The difference in resistance between copper wire and oxygen free copper wire is too small to be significant for speaker wiring. It can be considered to be ordinary copper wire as far as the recommended lengths of copper wire in the table. Oxygen free copper wire can be more expensive than ordinary copper wire.
