All of our soldering team are holders of
soldering certification to Military Quality
Standards.

The SUPRA Story

Prior to 1976 loudspeaker cables had no
identity. They were simply cables.
2 x 0.5 mm2 was the most usual size,
while for high specifications the only
alternative was 2 x 0.75 mm
And then there was SUPRA.

It began when we introduced SUPRA

2.5 and shook up the entire market with
a whole new concept. All this happened
in Sweden 1976. Since then the whole
world has followed after us. But then the
adjustable spanner, the propeller, the safety
pin and Dynamite have also come from
Sweden, so perhaps it is not so surprising.

Since SUPRA 2.5 was introduced, other
original ideas have come from SUPRA.
The Nylon screen, the SWIFT connector,
the stretch-proof multicore cable, the PLY
conductor concept, the Assurance of Cable
Directionality and the LoRad are all
examples of our forward thinking
technology.

The Classic Series

The SUPRA Classic Series comprises highly flexible cables containing tin
plated multi-stranded OFC copper of purity degree 5N, which means
>99.999% pure, i.e. purer than five nines. The insulation is a special ion
stable PVC which minimises corrosion of the sonically benign tin surface.
The tin contributes to a better sound quality by minimising the skin-effect
and making less current jumps between the wire surfaces.

This series covers all Hi-Fi applications from low power speakers, such as
rear speakers of home theatre systems, to high power systems with long
cable lengths.

Supra Ply, A Logical and Scientific Design

Before considering more special ’esoteric’ 2nd
and 3rd-order effects, such as conductor
metallurgy, the performance of audio cables is
principally determined by their series loop
resistance (R), their series loop inductance (L) and
their shunt capacitance (C). Both the absolute
and the relative values of R, L & C matter. For
speaker cables connecting high performance
amplifiers to every day electrodynamic (moving
coil or ribbon) speaker drive-units that are
desired to operate with fidelity across the audio
band, the R & L (cable resistance & inductance)
must both be low, while the value of C
(capacitance) does not matter much [1,2]. This is
so because current flow into conventional
speaker drive-units is relatively so much larger
than in line-level connections, and also
absolutely large, ranging to over 100 Amperes in
some instances. This is especially true of auto (12
volt) installations. But simply using a fat wire
gauge makes R low at the expense of increasing
L. This is musically unacceptable for high sonic
quality.

’Squaring the circle’ techniques to make this loop
inductance, L, low, simultaneous with low
resistance, include tapes, either stacked in
parallel pairs, or several arranged side-by-side in
ribbons, where the ends are X-connected. But of
course, these types are (i) impractical to fit to
nearly every known speaker connector (at least
without introducing discontinuities), (ii) are
stressed and may be unsightly when right angle

surface bends are required in domestic installa­tion, and (iii) are unsuited to for mobile use by
professionals. Litz techniques, i.e. multiple,
parallel, insulated conductors are more practical
in use and laying out, but when properly
executed, they are expensive. They are also
awkward to terminate and must be soldered.

Other types are grossly large, like industrial
pneumatic pipes, making them unsuited to
smaller domestic dwellings.

Conventionally, fat conductors’ high loop
inductance (which raises impedance at +6dB/
octave) is further raised due to internal eddy
currents causing ’Skin effect’. This acts like ’the
square root of an inductor’, i.e. progressively adds
a +3dB/octave component to the cable’s series
inductance. With typical speaker cable runs of a
few metres, the combined inductive effect is that
performance in moderately heavy, plain
conductors is measurably affected with steady
signals at or a little above 1kHz. Whereas for
music transients, even low bass qualities are
affected.

Conventional stranded cables with copper, silver
or related conductors suffer from complex
oxidation. The surface becomes a semiconductor.
The diodes so formed between the strands are not
seen by steady-state signals, but look like the
plates of a high value capacitor to transient
signals. This causes low-level energy storage and
release after transients, that is invisible to steady
state testing yet nonetheless perfectly audible

with many music recordings. This ’transversal
distortion’ may also be described in terms of the
TEM (Transverse Electro-Magnetic) Wave, which
takes a direct route, whereas electron flow is
’trapped’ inside individual, particular strands that
are commonly twisted away from the most
direct route, at each of the inevitable bends in a
stranded cable, when laid-out.

Supra Ply is able to be a large-section, low
resistance cable, while also overcoming skin
effect and transversal distortion, by using a
proprietary, pure tin plating. This has the double
benefit that tin and copper meld without
forming a diodic barrier (as with many silver­plated copper ’audiograde’ conductors) and that
tin strongly resists most common causes of
metal corrosion, and hermetically protects the
copper, making Supra Ply ideal for outdoor use.

By contrast, most audiograde cables claiming
highly pure copper or silver conductors are
either wholly unprotected from contamination,
initially by the out-gassing of the plastic
covering (even if PTFE/Teflon is used), and
eventually from the impure atmosphere - and
even from accidental immersion in liquids!
Some very expensive cables are protected only
by a very thin, initially good lacquer, that must
eventually crack, invisibly, with handling and age.

Even if oxidation should form on the outside of
Supra Ply, it will be sonically benign, as in
audiograde ’metal oxide’ resistors - which are
really tin oxide.

Ply Loudspeaker Cables

Other Advantages

For wiring-up, Supra Ply is easily formed. Unlike ribbons, tapes and Litzes, the
rectangular conductor section is instantly made circular, for insertion into the
circular-shaped receptacles of binding posts, 4mm (’Banana’), Speakon, XLR
and most other speaker connectors.

Supra Ply’s overall square X-section allows it to readily enter most connector
housings, too.

Supra Ply is also readily coiled up, like ordinary, inferior-sounding ’mains
power type’ speaker cables. It is therefore easy for professionals to use.
Sound producers can easily take Supra Ply to the mixing venue along with
their favourite mini-monitor speakers.

Demonstrating the Difference

Unlike some audiograde products, the benefits of Supra Ply (and other cables
employing similarly logically progressive philosophies) are readily shown by
comparative and repeatable measurements. These differences may be
portrayed in a number of realms.

Fig.1, in the swept frequency domain shows progressively increasing losses
above 1kHz for all cables, caused by inductance + skin effect - ranging up to
10dB at 20kHz or so, where ultrasonic sound from vinyl discs in particular, can
stimulate pleasure centres in the brain [3]. Here, Supra Ply’s healthy, low-loss
behaviour at the higher audio frequencies (and, by implication, the transient
parts of lower frequency music fundamentals) is made evident with a basic
’steady-state’ sine-wave sweep.

Fig. 2 & 3 are ’scope pictures, in the steady-state time domain. They show
typical damping (dynamic) differences, using a classic square wave. After a
transient event, Supra Ply both restrains the peaking and accelerates the
return of the signal voltage to zero volts, at the speaker end of the line. The
peaking of the wide-spaced cable demonstrates both bad damping, and hf
loss. These effects occur because spaced cable has high inductance and low
capacitance - the diametric opposite of what is required to drive ordinary
loudspeakers.

The radiation from unshielded loudspeaker cables is often stronger
than that from ordinary mains cables.

SUPRA screened loudspeaker cables radiate less interference to low
level circuits, inputs and interconnects.

The shielding is also highly effective in rejecting high frequency
interference, by minimising aerial pick-up.

The minimising of interference fields is recommended in all fixed
installations, with computers playing an increasing part in everyday
life. Sensitive networks of low level information control all kinds of
operations.

Meanwhile, multi room installations often require audio, video, data
and loudspeaker lines to run through ceilings and walls in very close
proximity.

Sword 3m (10 ft) pair

Supra’s flagship. Sword is a patented cable. The secret is the bifilar
wound litz conductors, each comprising 24 individually insulated
wires.
The bifilar winding is built with 12 of these wires helically wound in
one direction and 12 in the opposite direction. This divides the
magnetic field into opposing directions resulting in self-cancellation.
Because Sword’s conductors comprise a number of insulated wires,
dynamic skin effect is cancelled.
Therefore Sword behaves as a non-inductive and phase stable cable.
Patent holder: Johnny Svärd.

What does it sound like?

Supra Sword passes the most complex music transients without any
deformations. Signal delay is suddely the same at all musical
frequencies. Therefore it vanishes, giving a clear 3-dimensional
presence, a sure sign of the highest fidelity.

Patent holder: Johnny Svärd

Sword is available only as a terminated set

Owing to the special construction with two opposite wound wire groups
which cancel each other’s fields, the termination quality is very critical.

The termination is done with strong, gas tight crimping, so the joined
metals are fused into one unit. This is more pure and secure than any
soldering.

Sword is available in standard length of 3m pair, delivered in a Mahogany
wood case.

Termination: Spade/Banana/BFA combination connector.
Customized lengths available on order.

Accessories for Bi-Wiring

Bi-wiring is a separation of the music signal current between
power amplifer and loudspeaker drive-units into two cables;
one for the bass and one for the midrange/tweeter.
Bi-wire speakers are therefore equipped with separate inputs to
the crossover networks.
Bi-wiring makes an audible enhancement. The best
combination is a pair of Ply 3.4 or 3.4/S.

LoRad Screened Mains Flex, Patented

2

, highly flexible, specification 05VA7V-H 3G2.5.

2.5 mm
LoRad stands for Low Radiation of electric and magnetic alternating

fields.
Protects your equipment from radiated mains noise as well as from RF

pick-up.
The screen protects from the electric field and a short pitch twisting

protects from and cancels the magnetic fields.

This will typically result in a cleaner sound and more accurate
transients, which in turn give you a tighter bass, better 3-D presence
and stereo definition. Closer to the truth.

SUPRA’s screening concept is patented worldwide by Tommy Jenving.

LoRad Mains Flex

Supra LoRad is the sole audio grade mains cable in the
world with full European safety approval.

Safety approved in compliance with HD 21.5 S3

Tips and Tricks:
A simple way to check the cable radiation is to use an
AC field sensor.

Hold the AC sensor
against a cable and if it
lights up it means the
cable is radiating noise
fields. Of course, the cable
must be connected to the
wall socket that is
switched on.

Check LoRad in the same
way and you will find that
it does not indicate any
noise radiation.

AC sensors are available at Supra dealers or electrical stores.

DAC
Digital/Analogue Interconnect

Application examples: Digital audio with
XLR-interface 110 Ohm AES/EBU, or as a
common analogue interconnect with RCA
or XLR plugs.
Available in both Ice Blue and Anthracite
Grey.

EFF-I
Analogue Interconnect Cable

The multi test winner. Our best interconnect
for analogue audio, for example: CD to amp.
As well as being one of the world´s best for
analogue applications, it can also be used
for digital audio as a 75 Ohm RCA interface
or video interconnect.

1:1 1:1 1:1

Trico
Digital/Video Composite Cable

Our best video/digital cable.
Application examples: Composite video
such as, DVD to TV/projector and digital
surround sound from DVD to AV amp or
all other digital applications where True
75 Ohm impedance is critical. For signal
measurements, see page 29.

DAC Digital/Analogue Interconnect
Cable, AES/EBU Harmonised

A ’fast’ interconnect of extremely low capacitance.
In accordance with our design concepts, the
inductance is to be low for a loudspaker cable
whereas for an interconnect the capacitance is to
be low. Supra DAC is insulated with PE foam skin
which exhibits only 45 pF/m. It is screened with
our very efficient and strong semi-conductive
nylon ribbon. Supra DAC is also designed for
digital audio and is harmonised with the AES/EBU
standard. (Square wave of 60 MHz, impedance 110
Ohms, balanced.)

The very high frequency properties of Supra DAC
are outstandingly good, owing to its high velocity
factor.

The velocity factor of Supra DAC is as high as 78%
of the speed of light, owing to the low
dielectricity of the gas blown foam skin insulation.
With PTFE/Teflon it would have been only 71%.

The velocity factor can be calculated with the
simplified formula:

ν = √1/K

where K is the dielectricity factor of the insulation
material. (See page 27.)

More clean transients and thus improved space
dimension comes with the high velocity.

Loudspeaker Cables /// Interconnect Cables /// Connectors /// Interconnects ///

EFF-I Interconnect Cable
Analogue/Digital 75 Ohm

The dynamic influence of the skin effect is of
great sonic influence as music and also video
signals are nothing but variations. By means of
the Equalized Frequency Flow technique (EFF)
Supra takes skin effect into account. The EFF-I
cable consists of two tube-shaped conductors
with a wall thickness of 0.20 mm which is well
below the smallest skin depth within the audio
range. This makes a wide range of the music (or
video) frequencies pass through under the same
conditions.

Trico Digital/Video Composite Cable
75 Ohm, Co-axial

Supra Trico is an interconnect cable of very low
capacitance, insulated with PE foam which
produces only 58 pF/m and makes the cable’s
propagation velocity as high as 78% of the
speed of light.

Trico is double-shielded with a braided inner
screen of silver plated oxygen-free copper and an
outer of bare OFC-braid. The screens provide
efficient noise protection. The centre conductors
are made of silver plated OFC copper. The silver
plating of the conductor and screen enhances the
cohesive properties of the cable, at high
frequencies.

The high technology design of Trico produces an
extremely low attenuation: -0.6dB/100m at 1MHz
and -7.1dB/100m at 100MHz.

True 75 Ohm: The characteristic impedance is very
stable: +/- 1.5 Ohms from 1MHz up to 100MHz.

MBS is based on Supra’s unique Nylon
braid concept.

The advantages of Supra nylon screened
cables over ordinary braided cables are:

• High Tensile Strength

The tensile strength is 500N/50mm.

• Bending Fatique

In accordance with a military flex
test a cable must pass 30,000
bending cycles without damage.
After 90,000 cycles the test was
concluded without any damage to
the MBS cable.

• Environmental Immunity

Air humidity does not influnce the
cable’s electrical properties.

• Microphony

The softness of the Nylon screen in
combination with other design
features make MBS a quiet cable,
free from microphony.

More about the concept on page 16!

Loudspeaker Cables /// Interconnect Cables /// Connectors /// Interconnects ///

MB Series for Fixed Installations

The conductors are of the same design as of the MBS microphone cable
but the jacketing is thinner and the shielding is of polyester based
aluminium to better suit installation applications.

Tips and Tricks:
You can easily test the microphony of a cable:

Plug the cable into the mixer with the other end of the
cable open, without anything connected. Turn up the
volume and listen to how sensitive the cable is when you
touch it, tap it and move it, or slap it against a base floor,
as occurs with mic/guitar cables.

Multicore Cables for Stage Use, Pair Jacketed and
Stretch-Proof

SUPRA has developed a flexible multi-core cable for use on stage and
in heavy and rough handling situations. Every pair is individually
jacketed and is a complete cable. Simply solder on a contact - you
don’t even need to use Heat Shrink. Perfect when you need to make
up a line to a stage box. The screen is of semi-conductive nylon which
is extremely strong with regard to bend-fatigue and which at the
same time is highly resistant to electro-magnetic interference. A usual
problem with multicore cables which are used on stage and in other
non-permanent applications, is that the pairs in the middle of the
cable have less stretch tolerance than the outer layers, owing to the
spiralized configuration of the cable. Consequently the inner cables
are often stretched so much that the solder joints give way or the
conductors break when forced to take the whole strain. Supra has
solved this through increasing spiralization of the pairs towards the
centre, plus the omission of a pair at the exact centre, this being
replaced with a flexible plastic core.

SUPRA Multicore Cables are Designed for
Professionals

The advantages of Supra Nylon screened cables over ordinary
braided cables are:

• Tensile Strength

The tensile strength is 500N/50mm.

• Bending Fatique

In accordance with a military flex test a cable must pass 30,000
bending cycles without damage. After 90,000 bending cycles the
test of the Nylon screened Supra MBS was concluded without
any damage to the cable.

• Environmental Immunity

Air humidity does not influnce the cable’s electrical properties.

• Microphony

The softness of the Nylon screen in combination with other
design parameters makes a quiet cable, free from auto
microphonics.

The pairs are identified with jacket colours as well as with numbers.
See identification chart below.

• Totally shielded.

• No looseable screws. Only one retained screw.
Nothing to slip on to the cable before soldering.

• Strain relief: The screw serves also as a clamp
screw and since it is placed at a considerable
distance from the apperture there will be no
bending forces on the cable at the clamping
point.

Analogue Interconnects

All SUPRA connectors have shielding housings and the cables are
provided with Supra´s efficient screens which ensures noise rejective
interlinking.

The cables are developed with the focus on low capacitance, high
velocity factor and correct and stable characteristic impedance.

The results are improved definition and dynamics.

75 Ohm Interconnects:
Trico-RCA, Trico-BNC

The 75 Ohm digital interconnects are designed for RCA (Phono
connectors) interfaced transmission between CD transport and digital
to analogue converter. They have the capability to transfer the full
digital spectrum and can be used with a number of 75 Ohm
applications.

110 Ohm AES/EBU Interconnect: DAC-XLR

DAC-XLR is a balanced interconnect for digital transfer, mostly in
professional equipment.

DAC stands for Digital/Analogue Cable, not to be mixed up with DAC
converters.

From left: X-ZAC, ZAC Toslink, ZAC MinTos and ZAC Mini

ZAC Fibre Optic Interconnect

ZAC stands for Zero Attenuation Concept.
The innovative curving of the fibre core tip to get a zero divergence
loss enables plastic fibre optic to be used, and achieve the same
transmission quality as that of a glass fibre core in combination with
the strength and flexibility of the plastic core.
Properties and advantages of the fibre optic cable are:

Digital Interconnects

General:

Always, in digital applications, the use of a cable with the correct
characteristic impedance is very important. There are two standard
impedances:

• 75 Ohm S/PDIF interface which uses RCA connectors. This is most

• common in Hi-Fi applications from CD transport to DAC, as well as

• home recording.

• 110 Ohm AES/EBU interface which is balanced and has XLR

• connectors. This is mostly used in professional applications.

For example Supra DAC-XLR.

Trico Video Interlinks True 75 Ohm

These interlinks are made of Supra Trico
which is our best video cable.

The properties of Trico are the secret behind
a sharp and clean picture: True 75 Ohm for
low reflection losses, especially important for
longer lengths, and double shielding for the
least interference.

All connectors are fully shielding.

AV-2 S-Video Interlinks

S-video is a better transfer system, but takes
2 cores providing equal velocity and phase,
owing to the synchronising of the two
signals luminance and chrominance.

In order to achieve this, the True 75 Ohm
impedance is a very important property of
the cable.

All connectors are fully shielding.

Tips and Tricks:

For absolute super quality you can use
3 pcs of Trico-RCA for component
video.

A/V Cable Measurements

29

These measurements show that the quality of the Supra Cables is on
level with a MIL-spec cable and even outperforms it on velocity.

A Time-Domain Reflection (TDR) tester* detailedly analyses the response
and impedance match of a cable and the connectors used, using a pulse
that rises in 50 pS**.

In pictures 2 to 5, the 2nd step-up shows the effect of the 75 ohm
(video standard) cabling and connectors operating in a standard 50
ohm test system. In 2 & 3, the tidy ’rectangularity’ of the step shows
that the impedance of the 75 ohm section is quite purely resistive, i.e.
nearly ideal.

HH

Pict. 1 shows reference with
special GR-connectioned 50
ohm load, acting as a near pure
resistance at all frequencies to
above 2GHz (high RF).

Pict. 2 shows the response of
Supra Trico. See below for
explanation of the 2nd step.

BNC is better than RCA on digital interconnects.

The physical dimensions of the RCA connector prevent it from having
exactly 75 Ohm characteristic impedance. Therefore the BNC connected
version is always preferred when there is a choice.

Pict. 5 shows Trico with
phono/RCA plugs fitted. It
could be any of the other
cables. The RCA plugs’
inconstant impedance match
at high RF causes reflections
(seen as ’positive spiking’),
this kind of behaviour being
precisely why BNC plugs
were invented in the 1940s
as serious RF coax
connectors, to replace the
’failed’ first generation plugs,
namely RCA and UHF types.
Thus the RCA was re-cycled
as an audio plug.

The tested Supra Cables

Supra Trico

Pict. 3 shows the response of
Supra AV-3. See below also.

Pict. 4 shows response of
RG179, a top-grade, 75 ohm
coax made to US Military
standard MIL-C-17D. Note
that the two Supra cables
perform similarly cleanly.
Note also that all are fitted
with 75 ohm BNC plugs.

The timing of the steps (10ns** per L-R div) shows that the electrical
length of the Supra cables (in pictures 2 & 3) is shorter than the
reference, by about 14%. As the cable lengths were physically matched
to within 0.2%, this shows that signal speed in the Supra cables must
be higher - meaning closer to the speed of E-M waves in air.

Supra AV-3

*Originally devised & made in 60s by HP, today known as Agilent.

** pS = picosecs = millionth-millionth’s (1/1000,000,000,000
second). In air and ideal, air-insulated cables, EM waves travel 1m in
about 3300pS (3.3nS). In all plastic-insulated cables, the lower speed

increases the time to travel 1m by some 140 to 150%.

Tests originally performed by Ben Duncan Research in UK.

Technical Information

For those who prefer to make their own
cable sets and for carrying out servicing, we
have gathered the following configuration
tables. Please be aware of the importance of
the soldering quality. All Supra pre-made
cables are soldered with lead-free silver-tin
with copper and non-corrosive flux, available
as Multicore TSC-96, which we recommend.

The galvanic potential of silver is closer to
copper than is lead to copper and thus the
galvanic potential will be minimised.

Balanced connection with XLR

Signal source > Text reading this way >

Semibalanced connection with RCA

Poor solderings mostly due to either too high
or too low a temperature.

Flux is needed to get through the oxide and
avoid a dry joint, without overheating.

A dry joint might work very well for a period
of time but as the oxide grow between the
tin and the object there will eventually be a
poor connection. In the worst case the
conductors will loosen and create a short
circuit.

Directionality Assurance

All Supra cables are constructed with
attention to consistent and equal ‘direction’
in all the conductors. Simplistic electronics
theory says there is no ‘directionality’ in
conductors, but assumes conductors are
perfectly isomorphic. It also ignores the
inherently directional nature of signal and
energy flow. Yet electricity could not be sold
without ‘energy flow directionality’. [1]

In reality, practical conductors are drawn
many times - not cast. This creates highly
elongated crystal structures. This in turn
creates a physical (mechanical) directional
feature or ‘axial polarity’. Annealing and also
‘burning-in’ processes can reduce the
‘strength’ of the ‘drawing imprint’, but only
to a degree.

All conductors in Supra cables are
consistently arranged to point ‘forwards, in
the direction (left to right) implied by the
legend (text) printed on the cable jacket.
Directional consistency is ensured in two
ways. First, direction of the conductors to be
used in each cable is known from the spooled
direction of the conductors received from the
copper wire factory. That is a reliable method
because an efficient manufacturing process
is consistent and omits random re-spooling
steps.

Forward Thinking Technology

Second, the ‘directionality’ of conductors is
now able to be measured, and Supra cables
are the first in the world to benefit from a
spectral technique developed by audio
consultant Ben Duncan [2] in conjunction
with Jenving Technology AB. This employs
some special test conditions which better
approximate audio equipment’s real-world
usage than standard, pure signal sources. Test
results show typical increases in harmonic
(noise) levels 0.5dB when cables are
connected so the conductors’ drawn
direction opposes the signal flow direction. In
real use the noise difference, which is some
dB below the main signal, could be much
greater. From this, a reduction in such noise
(‘more clarity’) is what’s expected, and it is
also one of the things that is heard in
practice - when optimum conductor
orientation is discovered.

Experiences of Directionality

In ‘high-end’ audio, ‘

Directionality’ means: ‘a
cable used for audio signal transmission
offering better sound quality (in various
ways) when connected a particular way
round.’ To those sensitive to the sonic
changes, this is repeatable, over spans of
time, or in different systems. In other cases,
if the less good direction were chosen, it too
may approach the preferred direction after
burn-in, i.e. a period of use, simple ageing, or
even cryogenic treatment. Such ‘burn-in’
processes involve annealing of the metal.

Some pundits say that ‘directionality’ (in
cables) can be heard even on the low quality
‘curvy plastic’ low/mid-fi audio equipment
sold in high-street shops. On an higher
vector, a US high-end enthusiast/ researcher,
Doug Blackburn, suggests it is possible that
when audiophiles say they hear sonic
changes after changing polarity (by
swapping conductors at one point - not by
swapping ends as with conventional
directionality*) that they’ve actually heard
directionality instead. That’s because purely
digital (‘software’) polarity reversals mys­teriously don’t have the sonic attributes
associated with analogue signal polarity
reversal.

*Here, directionality effect being heard is in
the connected parts (eg. long inductor wires),
rather than in the preceding connective
conductors.

Tin Plating

A SUPRA concept for cleaner sound.
The tin is of higher resistance than copper and also protects
copper from bad sounding corrosion. It also minimises the
current jumps from wire to wire over corroded copper surfaces
while more of the signal passes through the pure copper inside
the wires. The tin layer also minimises the skin-effect, by acting
as a semi-Litz.

Silver Plating

Only when the frequencies are very high, as in digital signals,
does it seem wise to go the opposite way, i.e. to silver plate for
a lower surface resistance. At such high frequencies it is hard
to keep the signal inside the wire, so instead we design for an
easier surface current flow.

Digital Interlinks

Important properties of digital cables are a high propagation
velocity factor and a correct and stable characteristic
impedance (Z).

Analogue Interconnects

Low capacitance (C) is important.

Microphone and Line Cables

Low microphonic effect and low capacitance assist quality.

Loudspeaker Cables

Loudspeaker cables generally need to be of low inductance (L)
and preferably also of low resistance (R). Impedance is of
greater importance than simplistic theory suggests because
music comprises continuous transients. Phase shift in the
frequency domain equals smearing in the time domain (Less
distinct transients).

Directionality Assurance

All Supra Cables are constructed with attention to
directionality in the conductors. Supra is the first in the world
to prove directionality in conductors by measurements.
These measurements are carried out by Ben Duncan Research
on behalf of Jenving Technology. Explanation on page 30.
