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.\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eX-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.\u003cbr\u003e\u003cbr\u003eAs 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.\u003c\/p\u003e\n\u003cdiv class=\"additionalawards\" data-mce-fragment=\"1\"\u003e\n\u003ch2 class=\"awards\" data-mce-fragment=\"1\"\u003eFeatures\u003c\/h2\u003e\n\u003cdiv class=\"col2\"\u003eAt low frequencies both X-Tube\u003csup\u003eTM\u003c\/sup\u003e\u003cspan\u003e \u003c\/span\u003eand conventional stranded\/solid core speaker cables convey signals in a linear way.

For minimal ‘insertion loss’ - which is the reduction of signal strength at the end of the cable compared to that at the start - Reference Ethernet uses an aluminium mylar wrap, within a foil wrap, within a ferrite-impregnated jacket. As a result, the cable comfortably exceeds the CAT 8 insertion loss standard. This over-specified arrangement also means Reference Ethernet easily outperforms the CAT 8 standard for ‘attenuation-to-crosstalk ratio’ which is an indicator of the margin by which it avoids introducing any errors into the data stream.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eReducing return loss\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eReference Ethernet also performs way beyond the CAT 8 requirements where ‘return loss’ is concerned. Any impedance mismatch between the cable and the equipment it’s connected to can cause the signal to be reflected back and forth. Thanks to its precision-engineered, gold-plated Telegärtner plugs with 360-degree shielded die-cast zinc bodies, reflections are minimised and all of the signal is delivered to the load. The cable is finished in a stylish pearl white PVC jacket to compliment any hi-fi set-up.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCable OD (mm): 9 mm\u003c\/li\u003e\n\u003cli\u003ePlugs: Telegärtner Profinet CAT 8\u003c\/li\u003e\n\u003cli\u003eConstruction: F\/FTP\u003c\/li\u003e\n\u003cli\u003eConductor size: 24 AWG\u003c\/li\u003e\n\u003cli\u003eCharacteristic Impedance: 100 ohm\u003c\/li\u003e\n\u003cli\u003ePatch Cable Category: Class I CAT 8.1\u003c\/li\u003e\n\u003cli\u003eMaximum bit-rate: 40 Gb\/s\u003c\/li\u003e\n\u003cli\u003eColour: White Pearl\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"QED","offers":[{"title":"1.0M","offer_id":43002826784927,"sku":"","price":271.99,"currency_code":"CAD","in_stock":true},{"title":"2M","offer_id":43002826817695,"sku":"","price":287.99,"currency_code":"CAD","in_stock":true},{"title":"3M","offer_id":43002826850463,"sku":"","price":319.99,"currency_code":"CAD","in_stock":true},{"title":"5M","offer_id":43002828521631,"sku":"","price":375.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/5532\/6111\/products\/qed_reference_ethernet__cobra_89c8a83b-ff00-4eeb-9a7f-2b0d537aec93.jpg?v=1678376082"},{"product_id":"qed-reference-xlr-40-analogue-cable-pair","title":"QED Reference XLR 40 Analogue Cable Pair","description":"\u003cdiv class=\"qproductadditional\" data-mce-fragment=\"1\"\u003e\n\u003cdiv class=\"tabcontentmain\" data-mce-fragment=\"1\"\u003e\n\u003ch2 style=\"text-align: center;\"\u003e\u003cb data-mce-fragment=\"1\"\u003eReference Analog 40 XLR builds on the multi-award winning Audio 40 range of products, now available in XLR form.\u003c\/b\u003e\u003c\/h2\u003e\n\u003cdiv class=\"additionalawards\" data-mce-fragment=\"1\"\u003e\n\u003cdiv class=\"col2\"\u003e\n\u003cp\u003eXLR 40 is designed primarily for low capacitance as this has been identified by QED as a major factor which leads to a high fidelity experience.

And by combining X-Tube™ technology with its equally effective Aircore™ technology, QED also reduces the ‘proximity effect’ that can disrupt current distribution in a speaker cable.

Depending upon the capability of the receiving equipment this jitter can create audible problems with the digital audio signal. To put it simply jitter causes distortion in the signal. This is due to the interaction of the required frequency with the frequency of the jitter which causes harmonics to be produced that were not present in the original signal. The distortion is similar to a subtle version of the more familiar THD \u0026amp; intermodulation distortion present in many amplifiers. This problem inevitably increases listener fatigue making the music sound harsh or just simply not enjoyable. The listener therefore finds it more difficult to listen for long periods without taking a break. Because, by definition, listeners of high resolution audio files are most likely to be the most discerning, any extra jitter added to the audio datastream by a poor cable design might be noticeable. QED Reference High Resolution USB is therefore eminently suitable for Hi-Res audio applications simply due to its unrivalled and superior, measurable jitter performance which, as we have shown delivers a performance which is at once more musical and enjoyable and which enables a relaxed and long lasting listening session leaving hifi enthusiasts eager to repeat the experience.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cols\"\u003e\n\u003cdiv class=\"col2\"\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOutside diameter: 7 mm\u003c\/li\u003e\n\u003cli\u003eCharacteristic Impedance: 90 Ω +\/-5%\u003c\/li\u003e\n\u003cli\u003eSignal Pair Attenuation: \u0026lt; -0.11 dB\/m @ 480 MHz\u003c\/li\u003e\n\u003cli\u003ePropagation Delay: 26 ns max\u003c\/li\u003e\n\u003cli\u003ePropagation Delay Skew: 68 ps max\u003c\/li\u003e\n\u003cli\u003eMaximum Data Rate: 480 Mb\/s\u003c\/li\u003e\n\u003cli\u003eWorst case time related jitter: \u0026lt; 76 ps pk-pk (5 m cable measured at 480 Mb\/s; 440 mV rms)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col2\"\u003e\u003cimg src=\"https:\/\/www.qed.co.uk\/pub\/media\/wysiwyg\/qed\/refusb\/refusb-cut.jpg\" width=\"599\" height=\"496\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"QED","offers":[{"title":"0.6M","offer_id":45761717829791,"sku":"","price":171.99,"currency_code":"CAD","in_stock":true},{"title":"1.0M","offer_id":45761713569951,"sku":"","price":239.99,"currency_code":"CAD","in_stock":true},{"title":"2M","offer_id":45761713602719,"sku":"","price":259.99,"currency_code":"CAD","in_stock":true},{"title":"3M","offer_id":45761713635487,"sku":"","price":223.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/5532\/6111\/files\/a5392796-4e82-477f-959a-7dfc93df656e.jpg?v=1719005818"},{"product_id":"qed-performance-optical-graphite-cable","title":"QED Performance Optical Graphite Cable","description":"\u003cdiv class=\"qproductadditional\" data-mce-fragment=\"1\"\u003e\n\u003cdiv class=\"tabcontentmain\" data-mce-fragment=\"1\"\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cdiv class=\"cols\"\u003e\n\u003cdiv class=\"col2\"\u003e\n\u003cp\u003eOur Performance Optical Cable allows you to experience superior sound quality when connecting DAC's, TVs, CD players and Blu-Ray™ players to amplifiers or receivers.

Designed specifically for Supremus Zr cable, this unique contact expansion system securely clamps the rhodium-plated beryllium copper pins into the speaker terminals, while at the same time increasing the contact area of the plugs, simply by twisting the plug barrel until it is tight. And because it’s so very hard-wearing and resistant to oxidisation, rhodium can cope with the extra load exerted by our locking design – which ensures a perfect, maintenance-free connection.\u003c\/p\u003e\n\u003ch3\u003eAircore™ Technology\u003c\/h3\u003e\n\u003cp\u003eLoudspeaker cables with large cross-sectional areas are prone to skin effect, where high-frequency analogue music signals are forced to the outside of the conductor, and proximity effect that disrupts current distribution. QED’s innovative Aircore technology combines hollow tubular conductors – to minimise the skin effect – with polyester insulation and a special spiral construction to reduce the proximity effect. This highly effective combination evens out current density and significantly improves the cable’s uniformity throughout the audio band.\u003c\/p\u003e\n\u003ch3\u003e6.2 mm² Ultra-Low Resistance Conductors\u003c\/h3\u003e\n\u003cp\u003eBoasting a large cross-sectional area, the ultra-low resistance, silver-plated, oxygen-free copper conductors effectively bring the amplifier electrically much closer to the loudspeakers, enabling it to exercise better control over them, so the fidelity of the original music signal can be more accurately maintained.\u003c\/p\u003e\n\u003ch3\u003eCryogenic Treatment\u003c\/h3\u003e\n\u003cp\u003eCryogenic treatment improves the microstructure of the copper core by eliminating crystalline dislocations.
