SuperFlex Litz Copper Tonearm Wire
Tonearm wire has two basic requirements.
One, it must be flexible. Tonearm wire must not interfere with the motion of
the arm. Interfering with arm motion can introduce low level distortions that
obscure fine details. Two, it must be a top quality conductor, preferably Litz
copper. KAB would not have entered the wire making business if it weren't for
the lack of tonearm wire meeting those 2 basic requirements.
I have rewired hundreds of Technics arms over
the years. And have come to the conclusion that the companies making "tonearm
wire" have never actually rewired a tonearm. For if they had, they would
immediately realize that Teflon is perhaps the least desirable insulation.
First and foremost, tonearm wire must be flexible, and you cannot get there
with Teflon. And, worse yet, Teflon requires a graphite coating to eliminate
the triboelectric charge that occurs with motion. This charging and discharging
is what causes microphonics with Teflon wires. But there is a better
So, after many years, I am very excited to
finally introduce a tonearm wire made for people that actually rewire tonearms
and play records. KAB SuperFlex Litz tonearm wire. Each 34 gauge wire is
made up of 40 strands of 50 gauge pure copper litz conductors enveloped in a
very thin film of super flexible silicone. Our new tonearm wire lays as limp as
a wet noodle! It will not interfere with tonearm motion in any way. It will not
resonate in the audio band. It will not develop a static charge nor create
microphonics with motion. KAB SuperFlex is the definition of tonearm wire. Sold
in sets of 4 colors Red, Green, Blue and White.
KAB SuperFlex tonearm wire should be stripped with a good
quality mechanical wire stripper. Then lightly twirl the strands between your
fingers. Now, pre tin them by simply applying a soldering iron and solder, The
poly film will bubble off and the wires will tin very quickly. The wire is a
joy to work with, really. Just remember that the high degree of flexibility
requires that you handle the wires lightly. Do not stretch or tug on them. We
can make custom wire sets pre cut and tinned as well.
Also, check out our SpiralAir
Interconnects. They are a perfect match for an arm rewired with our
SuperFlex Litz tonearm wire.

| Litz wire is a type
of cable used in electronics to carry alternating current. The wire is designed
to reduce the skin effect and proximity effect losses in conductors used at
frequencies up to about 1 MHz. It consists of many thin wire strands,
individually insulated and twisted or woven together, following one of several
carefully prescribed patterns. This winding pattern equalizes the proportion of
the overall length over which each strand is at the outside of the conductor.
In this way, Litz construction:
- Optimizes cable bandwidth
- Eliminates individual strand interaction
- Eliminates oxidation effects due to aging
- Generally optimizes cable performance
- Provides peace of mind with regard to signal transfer
Silicone insulation has ultra flexibility which ensures
that your tonearm reveals it's maximum sensitive to stylus motion. Silicone
insulation is stable and will not harden over time. Because of it's supreme
flexibility, Silicone insulation eliminates audio band resonance and tribo
electric charge, Graphite coating is not required. Making KAB ultra flexible
tonearm wire a very quiet wire.Teflon & Heavy Copper Strands:

The dielectric is the insulator. Insulators are
assigned a number that describes the reduction in wave propagation speed
through it. For example, air is 1, Teflon is 2, thin silicone is 3, PVC is 3.4,
water is 80. That is the dielectric constant 2/. And it is only meaningful if
both send and receive conductors are immersed in the same dielectric, and if
the cable is long enough to contain a quarter wavelength.
websites spin long yarns about how audio waves propagate through cables. And by
the time you wade through it all, your thinking to yourself, Wow, this must be
really important! But while it is true that higher dielectric constants will
reduce the speed that a wave travels down the wire, it is important to consider
that audio is measured in milliseconds, cable velocity effects are measured in
nanoseconds. That's a ratio of a million to one!
I found one
reference that really nails this down: "If a long line is
considered to be one at least 1/4 wave in length, you can see why all
connecting lines in low frequency systems are assumed short. For a
60 Hz AC power system, power lines would have to exceed 775 miles in length
before the effects of propagation time became significant. Cables connecting an
audio amplifier to speakers would have to be over 2.3 miles in length before
line reflections would significantly impact a 20 kHz audio signal! " 1/ Now
imagine the impact 3 ft of interconnect has on velocity?
Now, capacitance per foot is still
important, But this will only come into play in complete cables, not loose
wires laying inside a tonearm wand. The total contribution there being a few
A word about wire plating
I have found that the
most neutral sound will come from pure copper. This makes sense if you
understand skin effect. The skin effect describes how higher frequencies
currents tend to crowd into the outer edges of the conductor. If you plate the
copper, you introduce skin effects that affect the treble quality. Tin plate
will lose detail, Silver plate will enhance detail. Our general recommendation
is not to use plating in wires that are not easily removable. And to not use
plated conductors at all if you are interested in neutral reproduction.
Litz wire describes a construction that
attempts to optimize transmission efficiency across a wide range of
frequencies. It does this by reducing the skin effect. A litz wire will be made
up of many strands of wire, each strand individually insulated. The diameter of
each strand is chosen to ensure that at the highest frequency, the electrons
occupy the entire cross section of that strand. The strands are then bundled
together to achieve the desired gauge and wound in a special pattern that
ensures that each strand appears on the outer edge of the conductor, repeating
over and over as the wire is produced. The advantages of Litz wire are many and
I can think of no disadvantages.
