Absolutely!\u003c\/h2\u003e\n\u003cp\u003eDigital Optical Audio cables are now used widely to connect audio source equipment such as TV's, CD players and Blu-Ray players to amplifiers or receivers. There are many advantages to using the optical output from your source equipment. The optical output provides complete electrical isolation between equipment eliminating ground loops and noise induced by large external voltages or currents. With fast digital signalling using twisted pair copper cables, problems such as near end crosstalk can cause distortion of the signal; these problems are eliminated by using the digital optical connection option.\u003c\/p\u003e\n\u003cp\u003eBecause of the very short distances and relatively slow data signalling speeds of the Toslink system it is possible to use very inexpensive plastic optical fibres (POF) made of an acrylic glass material known as PMMA (Polymethyl-methacrylate). These are usually 1 mm in diameter to fit the Toslink connector and of course their extra width only exacerbates the time smearing or jitter caused by the multi-modes within the fibre. Calculations have shown that a typical 1m cable with a PMMA fibre of refractive index 1.5 and a critical angle of 76 degrees has the potential to introduce jitter of up to 145ps into the SPDIF signal. These plastic optical fibres (POF) account for virtually all commercially available Digital Optical Audio cables available today.\u003c\/p\u003e\n\u003cp\u003eThe alternative to this situation adopted by QED in the new Glasscore™ technology cable is to employ multiple fibre bundles of ultra-fine boro-silicate glass optical fibres (GOF) of no more than 50um each (thinner than a human hair) to make up the 1 mm diameter necessary to conform to the Toslink standard connectors. In the new QED Reference Optical Quartz cable there are 210 such fibres each of which guide the light along a much tighter path making the different modes much more uniform than in the larger diameter single fibres.\u003c\/p\u003e\n\u003cp\u003eBecause the range of angles of incidence at which the light is accepted at the aperture of the cable is smaller and the critical angle of internal reflection in the glass is larger than in POF fibres the range of different paths taken by the light is reduced. In this way short data pulses are no longer artificially elongated or smeared by the physical process of travelling along the cable.\u003c\/p\u003e\n\u003ch2\u003eOur Take\u003c\/h2\u003e\n\u003cp\u003eAlmost all the optical cables sold today use acrylic strands to transmit the digital signal but not the QED Reference Optical Quartz Toslink cable. QED have instead developed their own proprietary technology called Glasscore which employs multiple fibre bundles of ultra-fine boro-silicate glass optical fibres. This Glasscore™ technology virtually eliminates timing errors and introduces much less distortion and jitter. This has the effect of increasing bandwidth and the accuracy of data transmission, making the QED Reference Optical Quartz one of the most natural sounding digital cables on the market today.\u003c\/p\u003e\n\u003ch2 class=\"main-features\"\u003eMain Features \u0026amp; Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Description: High Performance Optical Toslink cable\u003c\/li\u003e\n\u003cli\u003eProprietary Technology: Glasscore - a trademark of QED\u003c\/li\u003e\n\u003cli\u003eConstruction: Unique boro-silicate glass construction\u003c\/li\u003e\n\u003cli\u003eHighly Flexible: 210 x 50 micron optical fibre bundle\u003c\/li\u003e\n\u003cli\u003eBandwidth: Over 150MHz Bandwidth\u003c\/li\u003e\n\u003cli\u003eUltra Low Jitter: Yes\u003c\/li\u003e\n\u003cli\u003eUltra Low Loss: \u0026lt; 0.03 dB\/m\u003c\/li\u003e\n\u003cli\u003eResolution: Hi-Res 24 \u0026amp; 32 bit high resolution audio compatible\u003c\/li\u003e\n\u003cli\u003eAvailable Lengths: 600mm; 1 Metre; 1.5 Metre; 2.0 Metre; 3.0 Metre\u003c\/li\u003e\n\u003cli\u003eQED Product Code: QE3306\u003c\/li\u003e\n\u003cli\u003eManufacturer's Warranty: Lifetime - Does not cover misuse or abuse\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/span\u003e Features \u0026amp; Specifications Subject To Change Without Notice.

When measured at very high frequencies, these cables do exhibit cleaner signal transmission than your ordinary audio interconnects.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eAnamate RCA Plugs\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe QED Anamate plug is a variation of the innovative QED Analoc RCA plug found in Reference and Signature Audio 40 cables. A hollow oxygen free copper central pin is used to improve high frequency detail in the same way as the X-Tube speaker cables. To reduce swirling 'eddy currents' (that would otherwise oppose signal flow) a unique low mass plug design using two small, high purity copper ground leaves is used. Like putting wooden wheels on a Ferrari, conventional RCA phono plugs have the potential to undo all of the hard work carried out by our carefully designed cordage.

The foamed polyethylene dielectric is claimed to reduce the amount of signal lost to cable capacitance. QED's Analoc plugs are fitted, said to be a low eddy current design with copper instead of brass used. They feature an outer locking cylinder that needs to be screwed forward before the plug's 'blades' can be locked onto the RCA phono socket, then the locking cylinder needs to tightened backup for a (very) secure fit. The Signature Revelation speaker cable uses 10 silver-plated oxygen- free copper central conductors, which are claimed to provide very low resistance alongside high levels of detail. These cores are separately insulated and arranged around a hollow core of polyethylene; QED calls this its Aircore technology and it's claimed to reduce inductance.\u003c\/p\u003e\n\u003ch2\u003eSound Quality\u003c\/h2\u003e\n\u003cp\u003eBefore the QED loom, the panellists have taken a mixed view of the various wires played to them. They've found positives and negatives, liked some and been lukewarm about others. But two out of the three listeners express a strong preference for this set of cables, applauding it for its clean, open, even sound that doesn't try to do anything too clever. Instead it is very accomplished at almost every facet of the music, and makes things look rather easy.\u003c\/p\u003e\n\u003cp\u003e\"Everything is joined up,\" says one panellist, and so it proves. The Lorde track plays better than it has through most others here. Although not necessarily the warmest or most expansive, it just seems to gel the bass with the rest of the music – which is something several others fail to do.It doesn't sound too steely in the midband, giving a nice smooth sound to female vocals, and treble is crisp and finessed. Musically the loom works very well, the beat bouncing along in an enjoyable way. The result is a surprisingly easy listen, when previously the track hasn't quite made sense.The REM tune is described as sounding, \"head and shoulders better\" by one panellist. There is a fine sense of depth to what can sound a pretty close and claustrophobic mix. One can hear lots of detail too, with the keyboard backing track coming through from the second verse, where previously it had been submerged. Tonally the QED isn't the warmest or most sumptuous here, but it is very even and transparent and doesn't seem to be trying to add or subtract anything much. This means that it's likely to work well with a wide range of systems. Moving to the Duke Ellington piece and the pattern continues. One adoring panellist describes it as, \"good bass rhythm and control, nice, cohesive, great sound, head and shoulders better\".Another of the panellists isn't quite so enamoured; they appear to yearn for the expansive yet sumptuous midband of the Ecosse, and find the QED a little too anodyne and bland when playing Julian Lloyd Webber's cello work. All of which just goes to show how much taste plays a part, but still this remains a superb result considering its low price.\u003c\/p\u003e\n\u003ch2 class=\"main-features\"\u003eMain Features \u0026amp; Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Description: QED Reference Audio 40 Cable \u003c\/li\u003e\n\u003cli\u003eConductors: Silver Plated 99.999% Oxygen Free Copper (SPOFC) conductors with LDPE dielectric Asymmetrical twisted pair geometry\u003c\/li\u003e\n\u003cli\u003eShield: OFC shield giving 100% electromagnetic screening\u003c\/li\u003e\n\u003cli\u003eJacket: Zn\/Mn ferrite Jacket\u003c\/li\u003e\n\u003cli\u003ePlugs: Gold plated QED 'Analoc' RCA plugs\u003c\/li\u003e\n\u003cli\u003eCapacitance: 76pF\/m\u003c\/li\u003e\n\u003cli\u003eInductance: 0.37uH\/metre\u003c\/li\u003e\n\u003cli\u003eLoop resistance: 0.072 Ω\/metre\u003c\/li\u003e\n\u003cli\u003eDissipation Factor: 0.0059\u003c\/li\u003e\n\u003cli\u003eDirectional: Yes\u003c\/li\u003e\n\u003cli\u003eAvailable Length: 1 Metre\u003c\/li\u003e\n\u003cli\u003eQED Product Code: QE2453\u003c\/li\u003e\n\u003cli\u003eQED Lifetime Warranty: Yes - Does not cover misuse or abuse\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/span\u003e Features \u0026amp; Specifications Subject To Change Without Notice.

It uses QED's LDPE low loss dielectric along with pure oxygen free copper and the company's proprietary X-Tube technology. This results in a cable with sensational levels of clarity and detail yet which is surprisingly affordable. This kind of transparency at anywhere near this price is truly difficult for rivals to match.\u003c\/p\u003e\n\u003cp\u003eAll QED cables are designed using the top down principle. XT25 represents the core musical performance trickled down from QED's 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 QED will replace it free of charge.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eX-Tube Technology:\u003c\/strong\u003e 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-Tube 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLow-Loss Dielectric:\u003c\/strong\u003e 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. Like its predecessors, XT25 uses a specially formulated low-density polyethylene (LDPE) dielectric. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e99.999% Oxygen-Free Copper:\u003c\/strong\u003e 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 QED make the resistance of their speaker cables as small as possible. They 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 they make sure that there are no impurities in the copper which would defeat the object of making them so large. That's why QED use 99.999% oxygen-free copper exclusively.\u003c\/p\u003e\n\u003ch2\u003eWhat is Airloc?\u003c\/h2\u003e\n\u003cp\u003eAirloc is a form of cold weld system that permanently attaches QED Forté banana plugs and spades to the entire range of QED and many other speaker cables. One of the main reasons for choosing a QED speaker cable is the superior d.c. resistance characteristics offered by their exclusive use of 99.999% OFC or oxygen free copper conductors. It isn't the smart thing to then go ruin all this attention to detail by neglecting the most vulnerable area of the speaker cable chain - that of the physical interface between cable and amplifier or speaker terminals. Since the mid 1970's there has been more co-operation between manufacturer's to allow for easier installation of good speaker cables and most products allow for use of both banana plugs and spade terminals. No, you don't have to use them, but they definitely have advantages over bare wire alone. Why?\u003c\/p\u003e\n\u003cp\u003eSeen under a microscope the surface of a typical copper strand is very rough and so using normal screw type terminals - such as found on binding posts or cheap banana plugs - electrical contact is only made in a relatively small number of places. Add to this a layer of oxidation - which is inevitable if copper is exposed to the air for even a short time - and the combined resistance of the cable and its termination can creep back up to levels present in a more inferior cable.\u003c\/p\u003e\n\u003cp\u003eBy using a cold weld crimp type termination, QED Airloc Forté plugs squash the conductors and plug together to increase contact area and reduce resistance. By the time the full pressure has been applied the resistance of the joint has reached a minimum value.\u003c\/p\u003e\n\u003cp\u003eNow, because all the air has been removed from the joint there will be no oxidisation of the contact surfaces so the low resistance will remain for the lifetime of the cable. During the cold weld process the cable and plug become one solid piece of metal. Since the copper contact has been effectively removed from the resistance equation we can concentrate on the plug to terminal resistance.\u003c\/p\u003e\n\u003ch2\u003eWhat are QED Forté Plugs?\u003c\/h2\u003e\n\u003cp\u003eThe plugs themselves are made of solid brass which has roughly twice the resistivity of copper. For this reason the QED Forté 4mm banana plug was devised so that its cross-sectional area would be at least double that of the cable to which it was connected effectively cancelling out the extra resistance of the plug material. QED then plates the connector with high purity gold which has a resistivity almost as low as copper but more importantly does not oxidise in air. The relatively smooth gold surfaces provide a larger contact area than the uneven copper strands in the cable and because the gold will never oxidise the contact surface remains clean and low resistance for life.\u003c\/p\u003e\n\u003cp\u003eThe QED Forté plug pin section is designed to maximise contact area throughout the wide tolerance range encountered in 4mm amplifier and speaker sockets. Here some are quite tight whereas others are loose, so the spring loaded Forte blade is designed to fit into smaller and larger sockets with equal insertion force. This means that the contact area is maximised and the connection remains uniformly tight. QED Forté with Airloc technology is top-notch and delivers guaranteed low resistance and strength - for life.\u003c\/p\u003e\n\u003ch2\u003eIn The News\u003c\/h2\u003e\n\u003cp\u003eWe loved the more expensive XT40 for precisely the same characteristics shown by the XT25 – and that's the mark of a manufacturer that knows its identity. If you don't want to meet the cost of the former, this is a cable offering the same family sound for a tighter budget, and it won't leave you longing for the upgrade. We know QED for sensational levels of clarity and detail, and, even at this lower price, it doesn't disappoint. This kind of transparency is difficult for rivals to match. \u003cstrong\u003eWhat Hi-Fi? 5 Star Review\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eOur Take\u003c\/h2\u003e\n\u003cp\u003eQED XT25 is the sort of speaker cable that can really open up a system.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eX-Tube Technology:\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003eAt low frequencies both X-Tube and conventional stranded\/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-Tube retains a near-linear signal transfer, whereas the conventional cables fail to conduct uniformly across the entire conductor area.\u003c\/p\u003e\n\u003cp\u003eIn standard speaker cables at high frequencies current flow is highest at the periphery with rapidly deteriorating current density towards the centre of the conductor. The effect of this is to reduce the actual cross sectional area of the cable at 15kHz to less than 75% of that at low frequencies. This results in higher distortion and compromises the performance of the cable. X-Tube with polycore technology exhibits much lower self-inductance and is therefore less affected by this problem. The polycore technology reduces loop inductance to levels only achievable using more costly and difficult to terminate cables. So, with more high frequency detail, less distortion and greater performance, X-Tube delivers greater fidelity across the audio spectrum which would otherwise be lost in ordinary cables.\u003c\/p\u003e\n\u003ch3\u003eWhat is Airloc?\u003c\/h3\u003e\n\u003cp\u003eAirloc is a form of cold weld system that permanently attaches QED Forté banana plugs and spades to the entire range of QED and many other speaker cables.

The relatively smooth gold surfaces provide a larger contact area than the uneven copper strands in the cable and because the gold will never oxidise the contact surface remains clean and low resistance for life.\u003c\/p\u003e\n\u003cp\u003eThe QED Forté plug pin section is designed to maximise contact area throughout the wide tolerance range encountered in 4mm amplifier and speaker sockets. Here some are quite tight whereas others are loose, so the spring loaded Forte blade is designed to fit into smaller and larger sockets with equal insertion force. This means that the contact area is maximised and the connection remains uniformly tight. QED Forté with Airloc technology is top-notch and delivers guaranteed low resistance and strength - for life.\u003c\/p\u003e\n\u003ch3\u003eIn the News\u003c\/h3\u003e\n\u003cp\u003eFor anyone whose hi-fi is built upon clarity and analysis, these cables could be just the ticket.

However, at high frequencies, X-Tube retains a near-linear signal transfer, whereas the conventional cables fail to conduct uniformly across the entire conductor area. In standard speaker cables at high frequencies current flow is highest at the periphery with rapidly deteriorating current density towards the centre of the conductor. The effect of this is to reduce the actual cross sectional area of the cable at 15kHz to less than 75% of that at low frequencies. This results in higher distortion and compromises the performance of the cable. X-Tube with polycore technology exhibits much lower self-inductance and is therefore less affected by this problem. The polycore technology reduces loop inductance too levels only achievable using more costly and difficult to terminate cables. So, with more high frequency detail, less distortion and greater performance, X-Tube delivers greater fidelity across the audio spectrum which would otherwise be lost in ordinary cables.\u003c\/p\u003e\n\u003ch2\u003eAwards\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eWhat Hi-Fi?\u003c\/em\u003e\u003c\/strong\u003e awarded the QED Silver Anniversary XT \u003cstrong\u003e'Product of the Year'\u003c\/strong\u003e 3 years running and had this to say about this remarkable cable: \"nothing else at this price point sounds as superbly balanced and detailed\". \u003c\/p\u003e\n\u003ch2 class=\"main-features\"\u003eMain Features \u0026amp; Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Description: Unterminated speaker cable\u003c\/li\u003e\n\u003cli\u003eInsulation: High performance low density polyethylene dielectric\u003c\/li\u003e\n\u003cli\u003eConductors: Silver plated 99.999% OFC conductors\u003c\/li\u003e\n\u003cli\u003eUnique SPOFC triple braid 5 x 16 x 0.1mm\u003c\/li\u003e\n\u003cli\u003eSpecial Feature: X-Tube technology\u003c\/li\u003e\n\u003cli\u003eOutside Diameter: 3.90mm\u003c\/li\u003e\n\u003cli\u003eCross-sectional Area: 1.50mm²\u003c\/li\u003e\n\u003cli\u003eLoop Resistance: 21m\/m\u003c\/li\u003e\n\u003cli\u003eCapacitance: 50pF\/m\u003c\/li\u003e\n\u003cli\u003eInductance: 0.47H\/m\u003c\/li\u003e\n\u003cli\u003eDissipation factor: 0.0006\u003c\/li\u003e\n\u003cli\u003eTerminations: The best banana plugs for terminating this cable are the QED Airloc Banana Plugs.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eManufacturer's Warranty: Lifetime - Does not cover misuse or abuse\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/span\u003e Features \u0026amp; Specifications Subject To Change Without Notice.

This \"Proximity Effect\" also increases resistance as frequency increases. These phenomena have a detrimental effect on the fidelity of the sound you hear.

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. Like its predecessors, XT25 uses a specially formulated low-density polyethylene (LDPE) dielectric. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e99.999% Oxygen-Free Copper:\u003c\/strong\u003e 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 QED make the resistance of their speaker cables as small as possible. They 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 they make sure that there are no impurities in the copper which would defeat the object of making them so large. That's why QED use 99.999% oxygen-free copper exclusively.\u003c\/p\u003e\n\u003ch2\u003eQED Performance XT25 Speaker Cable Review\u003c\/h2\u003e\n\u003cp\u003eWe loved the more expensive XT40 for precisely the same characteristics shown by the XT25 – and that's the mark of a manufacturer that knows its identity. If you don't want to meet the cost of the former, this is a cable offering the same family sound for a tighter budget, and it won't leave you longing for the upgrade. We know QED for sensational levels of clarity and detail, and, even at this lower price, it doesn't disappoint. This kind of transparency is difficult for rivals to match. \u003cstrong\u003eWhat Hi-Fi? 5 Star Review\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eOur Take\u003c\/h2\u003e\n\u003cp\u003eQED XT25 is the sort of speaker cable that can really open up a system. If you have a system that is already bright and detailed then this may not be the cable for you. But if you have a balanced, natural sounding system and are looking to eke out that extra level of clarity while keeping a balanced sound signature then the XT25 could absolutely do the trick. Its level of transparency is sure to win lots of fans and when its affordable price is taken into consideration it starts to look like something of a bargain. We cannot recommend this cable highly enough.

Put simply, this is the best termination method to use with QED loudspeaker cables. \u003c\/p\u003e\n\u003ch2\u003eWhat Is Airloc?\u003c\/h2\u003e\n\u003cp\u003eAirloc is a form of cold weld system that permanently attaches QED Airloc banana plugs to the entire range of QED speaker cables. One of the main reasons for choosing a QED speaker cable is the superior d.c. resistance characteristics offered by the exclusive use of 99.999% oxygen free copper conductors. It seems a shame then to ruin all this attention to detail by neglecting the most vulnerable area of the speaker cable chain - that of the physical interface between cable and amplifier or speaker terminals.\u003c\/p\u003e\n\u003cp\u003eSeen under a microscope the surface of a typical copper strand is very rough and so using normal screw type terminals means the electrical contact is only made in a relatively small number of places. Add to this a layer of oxidation - which is inevitable if copper is exposed to the air for even a short time - and the combined resistance of the cable and its termination can creep back up to levels present in a more inferior cable.\u003c\/p\u003e\n\u003cp\u003eBy using a cold weld crimp type termination Airloc plugs squash the conductors and plug together to improve contact area and reduce resistance. Now, because all the air has been removed from the joint there will be no oxidisation of the contact surfaces either so the low resistance will remain for the lifetime of the cable. During the cold weld process the cable and plug become one solid piece of metal. Since the copper contact has been effectively removed from the resistance equation it only remains to concentrate on the plug to terminal resistance.\u003c\/p\u003e\n\u003ch2\u003eWhat Are Airloc Plugs?\u003c\/h2\u003e\n\u003cp\u003eThe plugs themselves are made of solid brass which has roughly twice the resistivity of copper. For this reason QED's 4mm banana plug was devised so that its cross sectional area would be at least double that of the cable to which it was connected, effectively cancelling out the extra resistance of the plug material. QED then plates the connector with high purity gold which has a resistivity almost as low as copper but, more importantly, does not oxidise in air. The relatively smooth gold surfaces provide a larger contact area than the uneven copper strands in the cable and because the gold will never oxidise the contact surface remains clean and low resistance for life.\u003c\/p\u003e\n\u003cp\u003eThe new strengthened Metal Airloc plug pin section is designed to maximise contact area throughout the wide tolerance range encountered in 4mm amplifier and speaker sockets. Here some are quite tight whereas others are loose, so the spring loaded blade is designed to fit into smaller and larger sockets with equal insertion force. This means that the contact area is maximised and the connection remains uniformly tight. QED Airloc technology; guaranteed low resistance and strength - for life.\u003c\/p\u003e\n\u003ch2\u003eOur Review\u003c\/h2\u003e\n\u003cp\u003eThese really are some of the best banana plugs available. Using the specialist QED crimping tool the metal of the cable and the metal of the plug are fused together into a cold weld which means once they're fitted these banana plugs are never coming off and will never get loose. The metal outer sleeve helps make these plugs something of a bargain, particularly considering the quality job they do.\u003c\/p\u003e\n\u003ch2 class=\"main-features\"\u003eMain Features \u0026amp; Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFour Red \u0026amp; Four Black QED 4mm Banana Plugs Pre-Fitted to a pair of Speaker Cables\u003c\/li\u003e\n\u003cli\u003e24k Gold Plated Plugs\u003c\/li\u003e\n\u003cli\u003eHigh Copper Brass Body\u003c\/li\u003e\n\u003cli\u003eAirloc Cold Weld System\u003c\/li\u003e\n\u003cli\u003eMinimum Cable Size 0.75 mm2\u003c\/li\u003e\n\u003cli\u003eMaximum Cable Size 5.5 mm2\u003c\/li\u003e\n\u003cli\u003eAccepts entire QED Cable range\u003c\/li\u003e\n\u003cli\u003eColour-Coded Metal Barrels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlease Note:\u003c\/strong\u003e These plugs are only sold pre-fitted to cable purchased from Audio Trends.
