A number of questions have come up recently about digital audio disks and
a whole bunch of subjects that I would rather not list here.  Well,
a lot of answers seem to bin in this months Stereo Review.  I don't
work for them, and I am not especially tring to boost their circulation,
but this months issue is especially good, with a section on the
DCD story that we probably should all read.  There is also a report from the
Vegas Consumer Electronics show, etc.  By the way, Carver is introducing
an automobile stereo add-on with his magic FM clean-up circuitry, which,
as we all know by know, reprocesses the AUDIO signal.  Sony has got a nifty
idea of their own ... And here's something to keep in mind.  Auto Antennas
are very directional.  Mounted on the right front fender, they will
probably (someone check me on this) give best reception towards the REAR LEFT
corner of the car.

Now my question.  I was in a high end shop recently, and I happened to need
a pair of patch cords.  I asked them what they had, and they showed me a
few pairs, at $30, $40, $50, $70, etc.  I asked what the difference between
two similar pairs, at $33 and had Litz Wire center conductors, and that the $55 pair had Litz Wire center
conductors AND Litz wire outer conductors.  Well, the thought of owning real
Litz Wire so thrilled me that I bought the $33 pair.

Question is, i''t using Litz Wire in the outer conductor of a Coaxial audio
cable a small bit of overkill?  Does Litz Wire really make an audible difference
when used between the preamp and power amp? between tape deck and preamp?
etc?

For the uninitiated, Litz wire (Check my spelling, please) is a braid of
sorts of seperately insulated conductors which moves each condutor from
surface to center and back in the same way.  It is designed to combat
the ``skin effect'' which allows higher frequencies less conduction in the
center or away from the skin of a conductor.  It grows worse as the conductor
grows better, and in a superconductor, no current at all travels below the skin.
It follows inevitably from Maxwells Equations, which are the governing laws
of electromagnetism in the commonly observed (non-quantuum) universe.
