2Cable ManufacturingThe Supra Cables are manufactured inour own in-house production.Made in Sweden.Cable TerminationAll of our soldering team are holders ofsoldering certification to Military QualityStandards.The SUPRA StoryPrior to 1976 loudspeaker cables had noidentity. They were simply cables.2 x 0.5 mm 2 was the most usual size,while for high specifications the onlyalternative was 2 x 0.75 mm 2 .And then there was SUPRA.It began when we introduced SUPRA2.5 and shook up the entire market witha whole new concept. All this happenedin Sweden 1976. Since then the wholeworld has followed after us. But then theadjustable spanner, the propeller, the safetypin and Dynamite have also come fromSweden, so perhaps it is not so surprising.Since SUPRA 2.5 was introduced, otheroriginal ideas have come from SUPRA.The Nylon screen, the SWIFT connector,the stretch-proof multicore cable, the PLYconductor concept, the Assurance of CableDirectionality and the LoRad are allexamples of our forward thinkingtechnology.

4Ply Loudspeaker CablesSupra Ply, A Logical and Scientific DesignBefore considering more special ’esoteric’ 2ndand 3rd-order effects, such as conductormetallurgy, the performance of audio cables isprincipally determined by their series loopresistance (R), their series loop inductance (L) andtheir shunt capacitance (C). Both the absoluteand the relative values of R, L & C matter. Forspeaker cables connecting high performanceamplifiers to every day electrodynamic (movingcoil or ribbon) speaker drive-units that aredesired to operate with fidelity across the audioband, the R & L (cable resistance & inductance)must both be low, while the value of C(capacitance) does not matter much [1,2]. This isso because current flow into conventionalspeaker drive-units is relatively so much largerthan in line-level connections, and alsoabsolutely large, ranging to over 100 Amperes insome instances. This is especially true of auto (12volt) installations. But simply using a fat wiregauge makes R low at the expense of increasingL. This is musically unacceptable for high sonicquality.’Squaring the circle’ techniques to make this loopinductance, L, low, simultaneous with lowresistance, include tapes, either stacked inparallel pairs, or several arranged side-by-side inribbons, where the ends are X-connected. But ofcourse, these types are (i) impractical to fit tonearly every known speaker connector (at leastwithout introducing discontinuities), (ii) arestressed and may be unsightly when right angleLoudspeaker Cables /// Interconnect Cables /// Connectors /// Interconnects ///Ply 2.0 Ply 3.41:1 1:1ItemMechanical SpecificationsElec.

Explanation on page 30surface bends are required in domestic installation,and (iii) are unsuited to for mobile use byprofessionals. Litz techniques, i.e. multiple,parallel, insulated conductors are more practicalin use and laying out, but when properlyexecuted, they are expensive. They are alsoawkward to terminate and must be soldered.Other types are grossly large, like industrialpneumatic pipes, making them unsuited tosmaller domestic dwellings.Conventionally, fat conductors’ high loopinductance (which raises impedance at +6dB/octave) is further raised due to internal eddycurrents causing ’Skin effect’. This acts like ’thesquare root of an inductor’, i.e. progressively addsa +3dB/octave component to the cable’s seriesinductance. With typical speaker cable runs of afew metres, the combined inductive effect is thatperformance in moderately heavy, plainconductors is measurably affected with steadysignals at or a little above 1kHz. Whereas formusic transients, even low bass qualities areaffected.Conventional stranded cables with copper, silveror related conductors suffer from complexoxidation. The surface becomes a semiconductor.The diodes so formed between the strands are notseen by steady-state signals, but look like theplates of a high value capacitor to transientsignals. This causes low-level energy storage andrelease after transients, that is invisible to steadystate testing yet nonetheless perfectly audiblewith many music recordings. This ’transversaldistortion’ may also be described in terms of theTEM (Transverse Electro-Magnetic) Wave, whichtakes a direct route, whereas electron flow is’trapped’ inside individual, particular strands thatare commonly twisted away from the mostdirect route, at each of the inevitable bends in astranded cable, when laid-out.Supra Ply is able to be a large-section, lowresistance cable, while also overcoming skineffect and transversal distortion, by using aproprietary, pure tin plating. This has the doublebenefit that tin and copper meld withoutforming a diodic barrier (as with many silverplatedcopper ’audiograde’ conductors) and thattin strongly resists most common causes ofmetal corrosion, and hermetically protects thecopper, making Supra Ply ideal for outdoor use.By contrast, most audiograde cables claiminghighly pure copper or silver conductors areeither wholly unprotected from contamination,initially by the out-gassing of the plasticcovering (even if PTFE/Teflon is used), andeventually from the impure atmosphere - andeven from accidental immersion in liquids!Some very expensive cables are protected onlyby a very thin, initially good lacquer, that musteventually crack, invisibly, with handling and age.Even if oxidation should form on the outside ofSupra Ply, it will be sonically benign, as inaudiograde ’metal oxide’ resistors - which arereally tin oxide.

developed by MaCurdy (1983), Altonji(1986), Blundell and Walker (1986), Arellano and Meghir(1992), Blundell, Meghir and Neves (1993) and Blundell, Duncan and Meghir (1998).The plan for the remainder of the paper is as follows. We begin the next section 2 with a descriptionof the key features of the model. Section 3 describes the data used for estimation and the tax policysetting. Section 4 discusses the estimation procedures and results. We then go on to investigate theoverall model fit, the implications for wage and employment behavior and the underlying elasticitiesin section 6. Section 7 We then turn to the use of the model for policy evaluation by an applicationto the 1999 WFTC and Income Support reforms operating in the UK; and finally section 8 presentssome concluding remarks.2 ModelWe develop a life-cycle model of education choice, consumption and labor supply with on-the-jobhuman capital accumulation. Individuals are risk-averse and face productivity shocks with a persistentstochastic structure. To account for the complex budget constraint our model embeds a detailedmicro-simulation model of the UK personal tax-benefit system. We allow for changes in familycomposition over the life-cycle, including partnering, separation and fertility. These occurrences mayhave great consequences for the cost of working, labor market attachment and value of future workand therefore, in retrospect, educational investments. However, we do not address the consequencesof in-work benefits on family formation. These are exogenously determined in our model.Below, we first summarize the key features of the model, emphasizing the timing of events, and thendetail its specification.2.1 The timing of events and decisionsWe start tracking women’s decisions from the age of 16 with the choice of education. 6 This choice isthe first step in defining a woman’s career, potentially affecting future human capital accumulationas well as changing her marriage market and the chance of being a single mother. 7Women choosebetween three alternatives: secondary (i.e. the compulsory level of education, completed by age 16),6 Some recent studies have added education decisions to the standard structural life-cycle model. Most have focusedon men, e.g. Keane and Wolpin (1997), Lee (2005) Adda et al. (2013) and Abbot et al. (2013). Studies focussing onwomen include Adda et al. (2011).7 This is consistent with literature showing that the marriage market is responsible for substantial returns to educationvan der Klaauw, 1996, Francesconi, 2002, Keane and Wolpin, 2010, Larsen et al., 2011, Chiappori, Iyigun and Weiss(2012).5

8Loudspeaker CablesNEW!Sword 3m (10 ft) pairSupra’s flagship. Sword is a patented cable. The secret is the bifilarwound litz conductors, each comprising 24 individually insulatedwires.The bifilar winding is built with 12 of these wires helically wound inone direction and 12 in the opposite direction. This divides themagnetic 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.Sword is available only as a terminated setOwing to the special construction with two opposite wound wire groupswhich cancel each other’s fields, the termination quality is very critical.The termination is done with strong, gas tight crimping, so the joinedmetals are fused into one unit. This is more pure and secure than anysoldering.Sword is available in standard length of 3m pair, delivered in a Mahoganywood case.Termination: Spade/Banana/BFA combination connector.Customized lengths available on order.What does it sound like?Supra Sword passes the most complex music transients without anydeformations. Signal delay is suddely the same at all musicalfrequencies. Therefore it vanishes, giving a clear 3-dimensionalpresence, a sure sign of the highest fidelity.Patent holder: Johnny SvärdLoudspeaker Cables /// Interconnect Cables /// Connectors /// Interconnects ///The Sword Combi ConnectorSword comes with crimp-fastened screw adaptors, anda set of connectors that can be screwed onto these.

Supra DAC is insulated with PE foam skinwhich exhibits only 45 pF/m. It is screened withour very efficient and strong semi-conductivenylon ribbon. Supra DAC is also designed fordigital audio and is harmonised with the AES/EBUstandard. (Square wave of 60 MHz, impedance 110Ohms, balanced.)The very high frequency properties of Supra DACare outstandingly good, owing to its high velocityfactor.The velocity factor of Supra DAC is as high as 78%of the speed of light, owing to the lowdielectricity of the gas blown foam skin insulation.With PTFE/Teflon it would have been only 71%.The velocity factor can be calculated with thesimplified formula:ν = √1/Kwhere K is the dielectricity factor of the insulationmaterial. (See page 27.)More clean transients and thus improved spacedimension comes with the high velocity.EFF-I Interconnect CableAnalogue/Digital 75 OhmThe dynamic influence of the skin effect is ofgreat sonic influence as music and also videosignals are nothing but variations. By means ofthe Equalized Frequency Flow technique (EFF)Supra takes skin effect into account. The EFF-Icable consists of two tube-shaped conductorswith a wall thickness of 0.20 mm which is wellbelow the smallest skin depth within the audiorange.

A/V Cable Measurements29These measurements show that the quality of the Supra Cables is onlevel with a MIL-spec cable and even outperforms it on velocity.A Time-Domain Reflection (TDR) tester* detailedly analyses the responseand impedance match of a cable and the connectors used, using a pulsethat rises in 50 pS**.In pictures 2 to 5, the 2 nd step-up shows the effect of the 75 ohm(video standard) cabling and connectors operating in a standard 50ohm test system. In 2 & 3, the tidy ’rectangularity’ of the step showsthat the impedance of the 75 ohm section is quite purely resistive, i.e.nearly ideal.HPict. 1 shows reference withspecial GR-connectioned 50ohm load, acting as a near pureresistance at all frequencies toabove 2GHz (high RF).BNC is better than RCA on digital interconnects.The physical dimensions of the RCA connector prevent it from havingexactly 75 Ohm characteristic impedance. Therefore the BNC connectedversion is always preferred when there is a choice.Pict. 5 shows Trico withphono/RCA plugs fitted. Itcould be any of the othercables. The RCA plugs’inconstant impedance matchat high RF causes reflections(seen as ’positive spiking’),this kind of behaviour beingprecisely why BNC plugswere invented in the 1940sas serious RF coaxconnectors, to replace the’failed’ first generation plugs,namely RCA and UHF types.Thus the RCA was re-cycledas an audio plug.Pict. 2 shows the response ofSupra Trico. See below forexplanation of the 2nd step.The tested Supra CablesSupra TricoPict. 3 shows the response ofSupra AV-3. See below also.Supra AV-3Pict. 4 shows response ofRG179, a top-grade, 75 ohmcoax made to US Militarystandard MIL-C-17D. Notethat the two Supra cablesperform similarly cleanly.Note also that all are fittedwith 75 ohm BNC plugs.The timing of the steps (10ns** per L-R div) shows that the electricallength of the Supra cables (in pictures 2 & 3) is shorter than thereference, by about 14%. As the cable lengths were physically matchedto within 0.2%, this shows that signal speed in the Supra cables mustbe higher - meaning closer to the speed of E-M waves in air.*Originally devised & made in 60s by HP, today known as Agilent.** pS = picosecs = millionth-millionth’s (1/1000,000,000,000 th ’s of 1second). In air and ideal, air-insulated cables, EM waves travel 1m inabout 3300pS (3.3nS). In all plastic-insulated cables, the lower speedincreases the time to travel 1m by some 140 to 150%.Tests originally performed by Ben Duncan Research in UK.

30Technical InformationFor those who prefer to make their owncable sets and for carrying out servicing, wehave gathered the following configurationtables. Please be aware of the importance ofthe soldering quality. All Supra pre-madecables are soldered with lead-free silver-tinwith copper and non-corrosive flux, availableas Multicore TSC-96, which we recommend.The galvanic potential of silver is closer tocopper than is lead to copper and thus thegalvanic potential will be minimised.Balanced connection with XLRSignal source > Text reading this way >Semibalanced connection with RCASignal source > Text reading this way >Connection of screened loudspeaker cables:Earth screw to chassisScreen Screen+- +Supra ScreenedLoudspeaker CableAmplifierLoudspeakerThe screen is to be connected to the amplifier chassis or any otherground point of the amplifier. No connection at the loudspeaker end.Poor solderings mostly due to either too highor too low a temperature.Flux is needed to get through the oxide andavoid a dry joint, without overheating.A dry joint might work very well for a periodof time but as the oxide grow between thetin and the object there will eventually be apoor connection. In the worst case theconductors will loosen and create a shortcircuit.DB-15 HD (VGA)Pin Function Pin Function1 Red + 92 Green + 10 Sync Ground3 Blue + 114 125 13 H-sync/C-sync6 Red Ground 14 V-sync7 Green Ground 158 Blue Ground Chassis ScreenNo screen connection to theloudspeaker-All Supra connectors are insulated withTeflon to withstand the correct solderingtemperatures (300°- 400°C).For these reasons we always recommendleaving the soldering of interlinks with aprofessional workshop.All of our soldering team are holders ofsoldering certification to Military QualityStandards.XLRPin Function Pin Function1 Ground/Screen 3 Cold2 HotDB-25 (D-sub)Pin Function Pin Function1 Left Front + 14 Left Front -2 Center + 15 Center -3 Right Front + 16 Right Front -4 Sub Woofer + 17 Sub Woofer -5 Left Surround + 18 Left Surround -6 Right Surround + 19 Right Surround -Ground chassis - Ground chassisS-video (Y/C)Pin Funktion Pin Funktion1 Luminance (Y) Ground 3 Luminance (Y)2 Chrominance (C) Ground 4 Chrominance (C)ScartPin Function Pin Function1 Audio Out Right 12 Data 12 Audio In Right 13 Red Ground3 Audio Out Left 14 Data Ground4 Audio Ground 15 Red RGB, C at Y/C5 Blue Ground 16 RGB Status6 Audio In Left 17 Video Ground (CVBS)7 Blue RGB 18 RGB Status Ground8 CVBS Status 19 Video (CVBS) Out, Y at Y/C9 Green Ground 20 Video (CVBS) In, Y at Y/C10 Data 2 21 Ground (Shield)11 Green RGBDirectionality AssuranceAll Supra cables are constructed withattention to consistent and equal ‘direction’in all the conductors. Simplistic electronicstheory says there is no ‘directionality’ inconductors, but assumes conductors areperfectly isomorphic. It also ignores theinherently directional nature of signal andenergy flow. Yet electricity could not be soldwithout ‘energy flow directionality’. [1]In reality, practical conductors are drawnmany times - not cast. This creates highlyelongated crystal structures. This in turncreates a physical (mechanical) directionalfeature or ‘axial polarity’. Annealing and also‘burning-in’ processes can reduce the‘strength’ of the ‘drawing imprint’, but onlyto a degree.All conductors in Supra cables areconsistently arranged to point ‘forwards, inthe direction (left to right) implied by thelegend (text) printed on the cable jacket.Directional consistency is ensured in twoways. First, direction of the conductors to beused in each cable is known from the spooleddirection of the conductors received from thecopper wire factory. That is a reliable methodbecause an efficient manufacturing processis consistent and omits random re-spoolingsteps.Forward Thinking TechnologySecond, the ‘directionality’ of conductors isnow able to be measured, and Supra cablesare the first in the world to benefit from aspectral technique developed by audioconsultant Ben Duncan [2] in conjunctionwith Jenving Technology AB. This employssome special test conditions which betterapproximate audio equipment’s real-worldusage than standard, pure signal sources. Testresults show typical increases in harmonic(noise) levels 0.5dB when cables areconnected so the conductors’ drawndirection opposes the signal flow direction. Inreal use the noise difference, which is somedB below the main signal, could be muchgreater. From this, a reduction in such noise(‘more clarity’) is what’s expected, and it isalso one of the things that is heard inpractice - when optimum conductororientation is discovered.Experiences of DirectionalityIn ‘high-end’ audio, ‘Directionality’ means: ‘acable used for audio signal transmissionoffering better sound quality (in variousways) when connected a particular wayround.’ To those sensitive to the sonicchanges, this is repeatable, over spans oftime, or in different systems. In other cases,if the less good direction were chosen, it toomay approach the preferred direction afterburn-in, i.e. a period of use, simple ageing, oreven cryogenic treatment. Such ‘burn-in’processes involve annealing of the metal.Some pundits say that ‘directionality’ (incables) can be heard even on the low quality‘curvy plastic’ low/mid-fi audio equipmentsold in high-street shops. On an highervector, a US high-end enthusiast/ researcher,Doug Blackburn, suggests it is possible thatwhen audiophiles say they hear sonicchanges after changing polarity (byswapping conductors at one point - not byswapping ends as with conventionaldirectionality*) that they’ve actually hearddirectionality instead. That’s because purelydigital (‘software’) polarity reversals mysteriouslydon’t have the sonic attributesassociated with analogue signal polarityreversal.*Here, directionality effect being heard is inthe connected parts (eg. long inductor wires),rather than in the preceding connectiveconductors.Information[1] For background, refer to extensiveinsights in ‘Black Box’ column, by BenDuncan, originally in Hi-Fi News & RecordReview, reprinted 73 part compendium 1994-2000 available from:www.hifiaccessoriesclub.com - orwww.proaudioaccessories.com.[2] Ben Duncan Research: www.BDR-UK.dial.pipex.com.

About...Additional Infomation and Formulas31Supra ColoursIce BlueNCS S0520 R90BAnthracite GreyNCS 7502 GUseful to know about...Tin PlatingA SUPRA concept for cleaner sound.The tin is of higher resistance than copper and also protectscopper from bad sounding corrosion. It also minimises thecurrent jumps from wire to wire over corroded copper surfaceswhile more of the signal passes through the pure copper insidethe wires. The tin layer also minimises the skin-effect, by actingas a semi-Litz.Silver PlatingOnly when the frequencies are very high, as in digital signals,does it seem wise to go the opposite way, i.e. to silver plate fora lower surface resistance. At such high frequencies it is hardto keep the signal inside the wire, so instead we design for aneasier surface current flow.Digital InterlinksImportant properties of digital cables are a high propagationvelocity factor and a correct and stable characteristicimpedance (Z).Analogue InterconnectsLow capacitance (C) is important.Microphone and Line CablesLow microphonic effect and low capacitance assist quality.Loudspeaker CablesLoudspeaker cables generally need to be of low inductance (L)and preferably also of low resistance (R). Impedance is ofgreater importance than simplistic theory suggests becausemusic comprises continuous transients. Phase shift in thefrequency domain equals smearing in the time domain (Lessdistinct transients).Directionality AssuranceAll Supra Cables are constructed with attention todirectionality in the conductors. Supra is the first in the worldto prove directionality in conductors by measurements.These measurements are carried out by Ben Duncan Researchon behalf of Jenving Technology.
