Hi-Fi Speaker Cables

Super Lumina speaker cables are designed to minimise the effect of external and internal interference sources and preserve maximum signal fidelity. The fundamental cable design consists of several individually-insulated multi-strand silver-plated copper conductors of varying diameters enclosed in a tin-plated copper shield. This is all enclosed in a soft outer jacket which facilitates easy installation whilst minimising microphonic interference. Each signal, return, ground and shield conductor is individually manufactured for its specific function. Each Super Lumina cable is hand-assembled at Naim Audio in Salisbury to the customer’s specification of length and termination. The process is intricate and highly-skilled, following detailed instructions which cover every aspect of the build. Every cable also goes through a proprietary de-stressing process to relieve the materials of the inherent stresses which are a result of the manufacturing process. This means the cables reach optimum performance with minimal run in time.  

During the development of Statement, our flagship amplification system, our engineers realised that they would need to design a whole new range of high-performance cables for it to reach its true potential.  With this in mind they began a development project to design interconnects and speaker cable that would meet Statement standards of performance. Through a deep understanding of material science and after thousands of hours testing in the listening room, the Super Lumina range was born. Designed to maximise the performance of Statement but equally at home in 500 Series and Classic Series systems, Super Lumina pre to power amp interconnects are available with DIN to XLR, and XLR to XLR terminations. Super Lumina source to preamplifier interconnects are available with DIN to DIN, DIN to RCA, RCA to RCA and RCA to XLR connectors. Features Super Lumina interconnects are designed to minimise the effect of external and internal interference sources and preserve maximum signal fidelity.The fundamental cable design consists of several individually-insulated multi-strand silver-plated copper conductors of varying diameters enclosed in a tin-plated copper shield.

Each signal, return, ground and shield conductor is individually manufactured for its specific function. The Naim Audio Air-PLUG The Super Lumina interconnects feature an advanced version of Naim Audio’s patented Air-PLUG technology first introduced for the Hi-Line. All DIN and XLR connectors use the Air-PLUG connector which is designed as a decoupling device to minimise microphonic interference and preserve the integrity of the audio signal. The new Super Lumina Air-PLUG features multiple individual aluminium rings which form the rear of the connector. These are screwed together to form an articulating section which inhibits the passage of unwanted energy, the choice of aluminium as a material enhances this process. The connector pins on DIN terminated cables also float within their sockets, extending the decoupling effect right to the point where the signal enters the product.

Luna’s small size and dynamic sound has made it Wireworld’s most popular speaker cable for custom installations and budget music systems.

XT40i with X-Tube™ Technology As befits a company rapidly closing in on its fifth decades at the forefront of speaker cable design, QED’s brand new XT40i speaker cable builds on the formidable reputation of the XT40 cable it replaces and offers a decisive step up in sound quality.This pure oxygen-free copper cable uses an evolution of QED’s established X-Tube technology to guarantee superb timing and stereo imaging, and adds the brand new and highly innovative Air Gap dielectric to bring unheard-of rhythmic accuracy and musicality to a cable of this modest price. Very low DC resistance adds unrivalled frequency response to XT40i’s already potent audio capability. The result is a cable that advances on the class-leading standards set by its predecessor.We urge you to audition XT40i - we’re confident you’ll agree it even outperforms alternative cables at many times the price. Prepare to be surprised and delighted. Air Gap dielectric By increasing the separation of the conductors inside the cable, and therefore the amount of air between them, QED has created a low-loss Air Gap dielectric. This technology halves the dissipation and capacitance characteristics of the cable, and results in numerous audible improvements - particularly where timing and rhythmic accuracy are concerned. Despite this increased separation, though, XT40i retains the sort of cross-sectional area that makes it ideal for long cable runs.  X-Tube technology Forming the cable conductors into a tube-like shape around a hollow insulating rod in the centre of the cable equalises current densities, delivers very low inductance and presents a consistent, even load to an amplifier. The result is a cable that retains more of the finest musical details, that handles rhythms and tempos in the most natural and musically satisfying way, and that outperforms rival designs costing far more. Specification: Outside diameter: 6 x 14 mm Conductor area: 4 mm² Dielectric properties: Air Gap (εr = 2.4) Conductor chemistry: 99.999% oxygen-free copper Dielectric properties: Air Gap Loop resistance: 8.0 mΩ/m Parallel capacitance: 35 pF/m Dissipation factor @ 10kHz: 0.0295 Self-inductance: 0.57 μH/m Gauge: 12 AWG

The journey to XT25..... The QED speaker cable story began in 1973, with the launch of the world's first specialist speaker cables, QED 42 and 79 strand, now household names in the audio industry. Building on this longstanding British speaker cable heritage, QED embarked on an exhaustive research program into cable parameters which began in 1995 and continues into 2017 with the release of “The Sound of Science”, a 40 page White Paper distilling the research published since 1973 by QED. These reports set out the “top down” design-principles that have resulted most recently in the development of QED XT25 loudspeaker cable – the new class leading standard in budget to mid-range speaker cables. What are the features which make this cable so special? X-Tube™ technology first came to prominence in 2005 with the launch of the world renowned Silver Anniversary XT, the most highly regarded mid-range cable in the world, winning the What Hi-Fi Product of the Year three years in a row. These design principles also grace the multiple award winning XT40 speaker cable and XT25. As frequency increases, electrons flow more and more towards the periphery of a conductor so that if the frequency is high enough only a very thin layer (or skin) on the outside of the conductor is used. This “skin depth” varies for different materials at a fixed frequency and in copper it means that if a conductor has larger than 0.66 mm² cross-sectional area not all of that area is available for an analogue music signal to use. In SAXT the “skin effect” problem was effectively eliminated by the use of X-Tube™ Technology which works by placing all of the conducting material around a central hollow insulating rod. However, for a.c. signals, changing magnetic fields generated by the flow of current set up eddy currents in nearby conductors which force current to flow only in areas furthest away from conductors carrying current in the same direction and vice versa. This “proximity effect” has a detrimental influence on current distribution in a speaker cable even if it utilises X-Tube™ Technology. With XT25 we tackle the proximity effect and the skin effect by combining our existing Aircore™ and X-Tube™ Technologies into a new X-Tube™ variation. By forming the conductors into a tube-like shape with a hollow centre, current densities at higher frequencies are maintained because the electric field which contributes towards the skin effect acts towards the centre of the conductor from where the conductive material has been removed. At the same time instead of using a braided structure a ring of conductors is formed into separate bundles with only a loose electrical association which are then twisted into a 90 mm lay so that no single conductor bundle remains on the inside or outside of the cable (and therefore prey to the proximity effect) for long enough for it to become an audible problem. This geometry promotes a more consistent signal distribution making for a more accurate musical reproduction. Low DC Resistance At QED we recognise that low d.c. resistance of the loudspeaker cable is of paramount importance for high-fidelity signal transfer. This is because the speaker presents a frequency dependent load to the amplifier of which the cable forms a variable proportion. If resistance is allowed to be too large then audible changes to the frequency response characteristics of the loudspeaker will be introduced which cannot be corrected for by the amplifier’s negative feedback loop. In order to provide a marked improvement over similarly priced cables in both our own and our competitors’ ranges without increasing the overall size and flexibility of the cable substantially, the cross-sectional area (CSA) of XT25 has been enlarged to 2.5mm2 of 99.999% oxygen-free copper. This instantly gives the new cable a low d.c. resistance and therefore a more accurate musical delivery. Low-Loss Dielectric It is not generally appreciated that the electrical signals moving at or near the speed of light in a wire do so via the medium of electromagnetic (EM) waveforms which exist within the dielectric which surrounds the conductors as well as within the conductors themselves. The movement of electrons along the conductor merely facilitates generation of the EM waveform as their “drift velocity” is only a few centimetres per second. It is therefore important to ensure that the dielectric material used to insulate and protect the central conductors of the speaker cable is of a type which “permits” the establishment of EM waveforms without appreciable loss. Dielectric losses are directly proportional to the “permittivity” of the material used and as this a measure of each material relative to that in a vacuum it should be as close to unity as possible. Like its predecessors, XT25 uses a specially formulated low-density polyethylene (LDPE) dielectric which at 1.69 has the lowest relative permittivity practically available. QED research has shown that low capacitance cables are generally preferred in listening tests over high capacitance counterparts and this is usually because low-loss dielectrics have been utilised. The use of LDPE and careful control of conductor spacing results in a cable with a very low capacitance per meter and a dissipation factor (loss tangent) of 0.0001 at 10 kHz. What is the result of all these techniques? The graph below shows how the dc resistance of XT25 remains effectively unchanged across the entire audible frequency band when compared to a conventional cable of the same cross-sectional area. Combined with the sonic advantages of a low loss dielectric the improvements in current distribution place the new cable in a class well above cables with a less sophisticated geometry. What makes XT25 unique? 1. Award winning heritage guaranteed All QED cables are designed using the top down principle. XT25 represents the core musical performance trickled down from our money-no-object Supremus cable in a more affordable package. QED has won more What Hi-fi? Awards than any other single brand and with XT25 this heritage is delivered at a sensible price. Unlike most other manufacturers, QED offer an unlimited lifetime guarantee which means that if your cable ever fails to deliver to its full potential during its lifetime we will replace it free of charge. 2. X-Tube™ Technology....but with a twist In loudspeaker cables high pitched sounds are forced to travel towards the outside of the conductor and so are able to use less and less of the available cross-sectional area as the pitch increases. This is called the “Skin Effect”. It means that for high frequencies the resistance of the cable appears to be much higher than it does for lower pitched sounds. Eddy currents in one conductor can affect the current flowing in an adjacent conductor so that currents flowing in the same direction move away from each other. This “Proximity Effect” also increases resistance as frequency increases. These phenomena have a detrimental effect on the fidelity of the sound you hear. The XT25 variation of QED X-Tu Insulation LDPE jacket with 100% coverage of Aluminium Mylar tape wrap Plugs and spades QED Airloc™ Forte banana plugsbe™ Technology solves these problems by creating a hollow tubular conductor geometry out of individual conductor bunches through which each frequency can pass with equal ease when compared to traditional solid or stranded conductors. 3. Low-Loss Dielectric Music signals in a loudspeaker cable move back and forth many times every second. The insulating material used to separate the send and return conductors from each other (the dielectric) has to be charged and discharged every time. Not all of the energy stored in the dielectric during each charge cycle is completely returned during each discharge cycle which has a detrimental effect on the fidelity of the sound you hear. That’s why at QED we use low-loss dielectric materials such as Polyethylene (PE) or Teflon™ (PTFE) in preference to cheaper PVC alternatives found in inferior unbranded cables. 4. 99.999% Oxygen-Free Copper Speaker cables need to have a large current carrying capacity. If the electrical resistance of the cable is too large, part of the music signal will be lost, causing a detrimental effect on the fidelity of the sound you hear. To stop this from happening we make the resistance of our speaker cables as small as possible. We do this by using the largest practical cross-sectional area of copper within the size constraints of each cable. In order to squeeze the last drop of performance from the conductors we make sure that there are no impurities in the copper which would defeat the object of making them so large. That’s why we use 99.999% oxygen-free copper exclusively. 5. Just Listen Unique proprietary technology and trademarked geometries plus our award winning heritage all combine to create audible sonic improvements when compared to other loudspeaker cables.

Technical Specifications: DESIGN: Dual DNA Helix  SIGNAL CONDUCTORS: Qty: 2 (16 strands)    Gauge: 16AWG  |  1.25 sq. mm CONDUCTOR MATERIAL: Oxygen-Free Copper INSULATION: COMPOSILEX 3 PLUG CONTACTS: Silver + Gold plated Uni-term NOTE: HES (Standard)

Super Lumina speaker cables are designed to minimise the effect of external and internal interference sources and preserve maximum signal fidelity. The fundamental cable design consists of several individually-insulated multi-strand silver-plated copper conductors of varying diameters enclosed in a tin-plated copper shield. This is all enclosed in a soft outer jacket which facilitates easy installation whilst minimising microphonic interference. Each signal, return, ground and shield conductor is individually manufactured for its specific function. Each Super Lumina cable is hand-assembled at Naim Audio in Salisbury to the customer’s specification of length and termination. The process is intricate and highly-skilled, following detailed instructions which cover every aspect of the build. Every cable also goes through a proprietary de-stressing process to relieve the materials of the inherent stresses which are a result of the manufacturing process. This means the cables reach optimum performance with minimal run in time.

Equator 2.0 offers an essentially neutral performance with none of the exaggerated treble detail frequently found at this price point. Equator is well suited as an upgrade for mid-level or older audio systems in need of a little ‘TLC.’Atlas Equator 2.0 is a 2mm² cable using OFC (Oxygen Free Copper) conductors contained in a high-density PEF dielectric (insulation layer) that’s far more efficient than PVC or polyethylene. The superior dielectric offers both a better measured performance and an audible improvement in dynamics. The core assemblies are contained in a cotton yarn in order to reduce microphony and the outer sheath is in a pearl white finish. Termination is with Z-plugs or our cold-weld high quality OFC spades. Specifications:Construction: Multi-coreMaterial: OFCDielectric: PEFScreen: NoneCapacitance: 70.51 pF/mInductance: 0.816 µH/mResistance: 0.0094 Ohms/mVOP: 0.73Outside Diameter: 8.5mm

Closely related to our groundbreaking Mythical Creature Series, the Folk Hero Series, comprising two models—Robin Hood and WilliamTell—are available with either Solid Perfect-Surface Copper+ or Solid Perfect-Surface Silver conductors. While the Mythical Creatures are all-out assaults on the state of the cable art, the Folk Heroes use all of the same technology with fewer conductors.Building on a solid base of tried and true AudioQuest technologies, the design team of Garth Powell and Bill Low specifically focused on addressing one of the most vexing issues plaguing speaker cable design: the mismatch between the amplifier’s source impedance and the speaker’s load impedance. By eliminating the speaker cable’s characteristic impedance (ZERO Technology), current compression and distortion of the signal/current transient are significantly reduced. The result is dynamic contrast, transient response, and bass slam that are rendered seemingly without effort, because the cable is not electrically impeding the music.Like the larger-gauge cables of the Mythical Creatures Series, William Tell and Robin Hood can be used in one of two ways: either employing the ZERO model for Full-Range, or by using the ZERO model in combination with a dedicated BASS cable, as a fully optimized BiWire Combination cable. Like their larger siblings, William Tell and Robin Hoodalso feature our patented common-mode noise-rejection technology. Along with the Mythical Creatures, these latest AudioQuest speaker cables significantly outperform previous technology at controlling and draining radio-frequency noise. ZERO: NO CHARACTERISTIC IMPEDANCE FOR UNCOMPRESSED CURRENT TRANSFER The integrity of any audio transient (instantaneous peak-to-peak voltage swing and current) delivered from a power amplifier to a loudspeaker has always been compromised. Whether the amplifier is valve or transistor, regardless of class of operation, the amplifier’s source impedance and loudspeaker’s load impedance are never critically matched. The speaker cable’s characteristic impedance is yet another culprit in a highly compromised non-linear electrical circuit. AudioQuest has always stated that all cables cause damage because the output is never as good as the input. However, by eliminating a speaker cable’s characteristic impedance, AQ’s ZERO Technology is an unprecedented step towards reducing that damage. The result is greater dynamic contrast, better audio transient response, and bass slam that are rendered seemingly without effort because the cable is not electrically restricting (strangling) the music. GROUND-NOISE DISSIPATION (GND) This extremely effective patented common-mode noise-rejection technology is deployed on the ground path in almost all AQ AC Power cables, in addition to in AQ Bass & Midrange model speaker cables. The effectiveness of GND compromises audio above 10,000Hz, preventing the dedicated Bass & Midrange cable from being ideal for Full-Range use. SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS Solid conductors prevent electrical strand-to-strand interaction, major sources of distortion. Surface quality is critical because a conductor can be considered as a rail-guide for both the fields within a conductor, and for the magnetic fields that extend outside the conductor. The astonishingly smooth and pure surface of all AudioQuest’s Perfect-Surface metals nearly eliminates harshness and greatly increases clarity compared to lesser materials. Extremely high-purity Perfect-Surface Copper+ further minimizes distortion caused by grain boundaries that exist within any metal conductor. CARBON-BASED LINEARIZED NOISE-DISSIPATION SYSTEM (NDS) Today’s environment is saturated with radio-frequency noise that is extremely difficult to filter or reject. The frequencies of this noise from satellites, cellular towers, and Bluetooth, etc., are so extremely narrow that a conventional shield, or a series or shunt filter, is wholly inadequate. Much of the low-level signal that carries the harmonics and spatial cues that define high-resolution audio is masked by induced radio-frequency noise. AQ’s comprehensive Linearized Noise-Dissipation System combines multiple shields and a carbon-based linearized resistive network that turns most of this noise into heat. By "linearized," we mean that the system is equally effective across extremely wide bandwidth, rather than at selected frequencies only, as is more common. The remaining bad energy is effectively drained away from the sensitive amplifier circuits via directionally controlled signal and shield conductors. 72V DIELECTRIC-BIAS SYSTEM WITH CARBON-LEVEL RADIO-FREQUENCY TRAP (DBS) All insulation is also a dielectric whose electrical properties affect the integrity of the signal. When the insulation is unbiased, dielectric-involvement (absorption and non-linear release of energy back into the signal flow) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a significant problem for very time-sensitive multi-octave audio. AudioQuest’s multi-patented DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes the nonlinear time delays, resulting in clearer sound emerging from a “blacker” background. The inclusion of an RF Trap (a technology developed for AudioQuest’s Niagara Series of power products) in the DBS battery pack further reduces radio-frequency noise. The DBS battery packs will last for many years. A test button and LED allow for the occasional battery check. DIRECTIONALITY All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. When applicable, arrows are clearly marked on the connectors to ensure superior sound quality. For most models of AQ cable, the arrows not only indicate the direction that optimizes metal-directionality as part of Noise-Dissipation, but also indicates non-symmetrical attachment of shield and GND in order to optimize full-system performance. ROBIN HOOD BIWIRING When possible, running separate cables to the treble and bass “halves” of a speaker considerably reduces distortion. BiWiring keeps the large magnetic fields associated with bass energy out of the treble cable, allowing the delicate upper frequencies to travel a less magnetically disturbed path, like taking the waves out of the water when you swim. The “Rocket” models of AQ speaker cable have two autonomous internal constructions, facilitating proper BiWiring within a single cable. The “Type” models of AQ speaker cable can be doubled-up, using one for treble and one for bass. However, doubling-up AQ’s ZERO Technology cables can be less of an improvement because of ZERO’s unrestricted wide bandwidth – using two ZERO Full-Range cables can actually allow more RF energy into the amplifier, whereas using a BASS with GND Bass & Midrange cable in combination with a ZERO cable for Treble significantly reduces total RF Noise. The BASS cable’s patented Ground-Noise Dissipation (GND) drains RF energy away from the amplifier’s output. When properly implemented, BiWiring has always been a way to get better performance for the same or less money. With GND, the improvements from BiWiring are considerably more dramatic. Robin Hood BASS with GND is an ideal cable for the Bass and Midrange inputs of either a BiWireable or TriWireable loudspeaker when used in combination with Robin Hood ZERO or Robin Hood SILVER Full-Range cables. FOLK HERO COLD-WELDED TERMINATIONS Folk Hero cables are Cold-Welded to AudioQuest’s extremely pure Red Copper Spades or Bananas. The bare copper is submerged (hung) in a vat of pure silver instead of being tumbled in a lower-grade solution. AudioQuest speaker breakouts and plug casings are not metal in order to not disrupt the signal’s magnetic field, and to not induce RF Noise into the conductors.

ROBIN HOOD BIWIRING When possible, running separate cables to the treble and bass “halves” of a speaker considerably reduces distortion. BiWiring keeps the large magnetic fields associated with bass energy out of the treble cable, allowing the delicate upper frequencies to travel a less magnetically disturbed path, like taking the waves out of the water when you swim. The “Rocket” models of AQ speaker cable have two autonomous internal constructions, facilitating proper BiWiring within a single cable. The “Type” models of AQ speaker cable can be doubled-up, using one for treble and one for bass. However, doubling-up AQ’s ZERO Technology cables can be less of an improvement because of ZERO’s unrestricted wide bandwidth – using two ZERO Full-Range cables can actually allow more RF energy into the amplifier, whereas using a BASS with GND Bass & Midrange cable in combination with a ZERO cable for Treble significantly reduces total RF Noise. The BASS cable’s patented Ground-Noise Dissipation (GND) drains RF energy away from the amplifier’s output. When properly implemented, BiWiring has always been a way to get better performance for the same or less money. With GND, the improvements from BiWiring are considerably more dramatic. Robin Hood BASS with GND is an ideal cable for the Bass and Midrange inputs of either a BiWireable or TriWireable loudspeaker when used in combination with Robin Hood ZERO or Robin Hood SILVER Full-Range cables. FOLK HERO COLD-WELDED TERMINATIONS Folk Hero cables are Cold-Welded to AudioQuest’s extremely pure Red Copper Spades or Bananas. The bare copper is submerged (hung) in a vat of pure silver instead of being tumbled in a lower-grade solution. AudioQuest speaker breakouts and plug casings are not metal in order to not disrupt the signal’s magnetic field, and to not induce RF Noise into the conductors.

This Double Star-Quad Geometry “Rocket” cable does not look normal on the outside, and it is not at all normal on the inside. A sophisticated combination of extraordinary materials and extremely refined design allows the Rockets to honor all types of music equally.SOLID LONG-GRAIN COPPER/PERFECT-SURFACE COPPER (LGC/PSC) CONDUCTORS: Rocket 33 uses a carefully finessed combination of Long-Grain Copper and extremely high-purity Perfect-Surface Copper. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance. The astonishingly smooth and pure PSC further eliminates harshness and greatly increases clarity.CARBON-BASED NOISE-DISSIPATION and CROSS-TALK-DISSIPATION SYSTEMS (INSULATION): The four negative conductors in Rocket 33 are insulated with partially conductive Carbon-Loaded Polyethylene. This remarkable material damps radio-frequency garbage from being fed back into the amplifier. The sonic benefit is exactly the same reduction in “hash” and better dimensionality that comes whenever RF garbage is reduced in an audio circuit. Rocket 33 uses Nitrogen-Injected Foamed-Polyethylene Insulation on its positive conductors because air absorbs next to no energy, and Polyethylene is low-loss with a benign distortion profile. Thanks to all the air in Foamed-Polyethylene Insulation, it causes much less of the “out-of-focus” effect common to other materials.DOUBLE STAR-QUAD GEOMETRY: The relationship between conductors defines a cable’s most basic electrical values (capacitance and inductance). However, even when those variables are kept in a reasonable balance, the relationship between conductors can be varied in ways that greatly affect the sound. The Double Star-Quad construction of Rocket 33 allows for significantly improved dynamic contrast and intelligibility compared to parallel conductors.

A sophisticated cable engineered to offer a higher level of transparency than products typically supplied in ‘single-brand’ systems.It’s relatively easy to deliver an improvement in a specific area, but more difficult to create a cable that improves on overall detail, accuracy and open-ness without losing the signature speed and character of these systems. All Atlas cables are designed to impose as little of any inherent character as possible, achieved through careful selection of materials and construction methods, but we feel this latest generation Hyper cable is exceptionally transparent, allowing the equipment characteristics to be conveyed intact.The cable employs conductors comprising 72 0.25mm² high-purity OFC (Oxygen Free Copper) strands encapsulated within a carefully selected high-efficiency PTFE (Teflon™) dielectric coating. The resultant conductor is embedded within an anti-vibration filler and finished in the Hyper gloss black sleeve.Hyper 3.5 is the first cable in the Atlas product hierarchy which uses our Transpose Modular Termination System. Default termination is with our precision fit solder-free Expanding Plugs, suitable for standard 4mm sockets. Transpose options include Z-plugs or OFC spades in gold or silver.Specifications:Construction: Multi-coreMaterial: 6n OFCDielectric: PTFE (Teflon™)Screen: noneCapacitance: 0.0049 ohm/m;Inductance: 0.592 µH/mResistance: 0.0049 ohm/mVOP:  Outside Diameter: 8.5mm

Ascent is the first speaker cable in our product hierarchy to use OCC (Ohno Continous Casting) copper connectors with a total 2.0mm² diameter. These ultra high purity ‘6N’ (99.99997% purity) conductors are extremely transparent to the signal being passed, their mono-crystal structure ensuring minimum signal loss. For the dielectric, we use a high-efficiency PTFE (Teflon™) which again imposes virtually no signal degradation.In conjunction with our cold-weld, wideband Transpose connectors, which give a superior connection to conventional solder or screw fixing, the result is a cable with little discernable character which allows your system to convey a level of detail, speed and dynamics which might well surprise you.Specifications:Construction: Multi-coreMaterial: OCCDielectric: PTFE (Teflon™)Screen: N/ACapacitance: 90.54 pF/mInductance: 0.557 µH/mResistance: 0.0133 Ohms/mVOP: 0.74Outside Diameter: 8.2mm  

Mavros uses very high purity OCC (Ohno Continuous Casting) copper conductors. The OCC process is named after professor Atsumi Ohno, who in the late 1970s, discovered that by heating the drawing mould to a higher temperature than the molten copper you intend to cast, then cooling it soon after, the result is one long, high purity (99.9997%) metal crystal.These high-purity monocrystal conductors are used in a multi-stranded layout, wrapped in individual low-loss microporous PTFE (Teflon™) insulators, and twisted to help lower electromagnetic interference. The four separate conductors are then wrapped in cotton, an additional layer paper, then wraps the assembly in PVC and shrouds it in an outer black cotton sleeve.In the bi-wire 2–2 and 2–4 configurations, two additional solid conductors are dedicated to the mid/high frequencies, facilitating a more stable and open stereo image.This obsessive attention to detail – and the combination of materials & assembly methods which was only finalised after exhaustive testing – produces a cable which HiFi World’s reviewer described as‘ the best he’d ever heard’ and HiFi Plus summarised as ‘one of the very, very best.  The goal to make cables which have no discernable character or sound of their own, which would in itself be a form of distortion – Mavros is engineered to ‘disappear’ in your system, leaving the performance of your equipment to speak for itself. It should be noted though that Mavros requires a ‘burn-in’ period during which the sound will continue to improve.Specifications:Construction: Multi-core LF/MF, Solid core HF (1.5mm)Material: OCCDielectric: Microporous PTFE (Teflon™)Screen: noneCapacitance: 111.14 pF/mInductance: 0.3412 µH/mResistance: 0.0035 Ohm/mVOP: 0.77Outside Diameter: 10.22mm

Equator 2.0 offers an essentially neutral performance with none of the exaggerated treble detail frequently found at this price point. Equator is well suited as an upgrade for mid-level or older audio systems in need of a little ‘TLC.’Atlas Equator 2.0 is a 2mm² cable using OFC (Oxygen Free Copper) conductors contained in a high-density PEF dielectric (insulation layer) that’s far more efficient than PVC or polyethylene. The superior dielectric offers both a better measured performance and an audible improvement in dynamics. The core assemblies are contained in a cotton yarn in order to reduce microphony and the outer sheath is in a pearl white finish.
