I might have misunderstood that article, but so would
anyone reading it who was not deeply familiar with
what you mentioned. To us, it simply says
"no matter how hard you try, you are not going
to get there".
I guess one has to create a story in order to advertise
a product. I don't think you can criticize that.
But you could criticize the validity of their claim
with respect to their DBS system. Personally I don't
see why they have to go out of their way creating something
just to sell cables if it does not improve the sound.
In my previous job working in signal integrity,
a circuit board sometimes needs to be baked in heat
to improve jitter performance. It has to do with
dielectric absorbing moisture and when it is baked,
it allows the moisture to escape. So the state
dielectric is pretty important to the electrical
current.
Here is an interesting interview with AudioQuest
founder. The last paragraph is on wire directivity.
(He's a close cousin to GeoffKait).
First, we show that better stranded conductor
design, even with “both hands
behind our back”, as I call the constraints of
a stranded parallel cable, is still an arena in
which considerable improvement is possible,
and with less than half as much metal for less
than half the price.
Then, we use a cable of identical design,
except with solid conductors—a fun process
that usually provokes at least one mumbled
comment to the effect that, “if it’s that
obvious, how come everyone doesn’t do it?”
Good question.
Next, using the exact same solid conductors,
we share the audible performance difference
between parallel and twisted-geometry
cables, where geometry changes alone
can yield a surprisingly more open and
subjectively more dynamic presentation.
Going further, we move to a cable of
identical design, but with higher quality
copper conductors, and once again, the
clear sonic difference has a clear causeand-
effect.
Last in this progression is another pair of the
same better-metal cables, except with our
Dielectric-Bias System (DBS) attached. We
use identical cables except for the DBS—a
controlled experiment with a single variable
in-play: namely, the amount of interference
caused by the insulation, the dielectric.
Directionality is our honorary fifth element
or ingredient, although because it is a factor
always in play with any cable, and not part
of any particular design hierarchy, it doesn’t
quite fit in the same category as the others.
All drawn metal has a directional impedance
variation at higher RF/EMI noise frequencies.
By ‘law’, energy must follow the path of least
resistance, so we employ this impedance
variation as a mechanism for consciously
directing noise either to Earth or to
whichever attached circuit is less vulnerable
to noise. The key is to direct noise to where it
will do the least damage.
