It's hard to believe, and hard to believe this was written by native
English speakers
http://www.arkanaresearch.com/company/about/
Having (tried) to read through information posted on the web site all I
can say is that Arkana Research would be well served if they posted a
"from beyond the grave" recommendation from the late HP. In lieu of that
they could just buy some advertising in a few of the high end audio
publications and thus assure themselves several glowing reviews of their
magical (and very pricy) cables.

Disturbing.

From the 2nd link:
-"Two facts are considered as a very important advantage. First the
selected conductors possess a very low capacity per unit length ( C ) ~
1*10-7 F/km and low inductance per unit length (L) ~ 0,2*10-3 H/km.
Second, these values are constant in a wide temperature range. The
values of the per unit length for capacity and inductance are in this
case a lot lower than the corresponding values for traditionally used
metals (such as copper and silver). An additional advantage of the
metals in question is the fact that they practically do not have any
thermal noises of their own, typical for conventional conductors."-

Among the disturbing text is of course the electrical values:
C = 1x10-7 F/km = 1x10-10 F/m = 100 pF/m = ~30.5 pF/ft

I = 0.2x10-3 H/km = 0.2x10-6 H/m = 0.2 uH/m = ~0.061 uH/ft

Basically a low inductance cable (not as low as Kimber 8TC - $6.00/ft)
with typical capacitance equivalent to Belden 10AWG wire ($0.75/ft)
assuming we're talking about speaker cables where longer lengths matter.
They don't list resistance which would be even more important for this
application.

Don't see how values being constant over a "wide temperature range"
matters; I hope we're all listening at reasonably comfortable room
temperature. :-)

Merry Christmas everyone...

Disturbing. Evidently these guys are masters of alchemy.

Wow you actually took the time to read that horrible hash of
pseudo-science, marketing trash and audiophile buzzwords and yet still
felt it was necessary to debunk some the nonsense. While I respect your
commitment to science and truth, I would have fully understood if you
(or anyone else for that matter) just simply dismissed it for worthless
garbage. When does one ever see scientific formulas in ad copy except
when they are try to sell snake oil? Dead give away and something which
should send your BS meter deep into the *RED*. Perhaps it did and you
were just having a little fun.

Best holiday wishes to you and everyone!

Yup. Just having fun! Was curious if their claims of inductance and
capacitance was even in the ballpark :-).
