Whether you’re connecting your TV to a sound bar or music server to a DAC, QED has a digital cable to meet your requirements. Our cables are tried and tested to ensure you get the best performance from your digital sources.
When connecting your analogue sources such as your CD player or turntable to your amplifier, here at QED, we have a cable to suit your system. From our entry level Profile cable through to our flagship Signature Interconnect.
Using our unique Tri-Conductor technology and Neutrik XX-14 balanced plugs, our XLR cables offer the cleanest possible sound from a specialist XLR cable, whilst also incorporating our Ferrite insulation to eliminate timing errors.
An alternative to optical, our premium digital coaxial cables use a specially designed cable cordage and unique plug design to achieve the precise signal characteristics required for high resolution and multi-channel audio.
With our high end USB A-B we isolate the power and data conductors preventing any potential cross talk, therefore meaning less jitter and an enhanced audio performance.
For use with Laptops/Computers and portable headphone amps/dacs, the QED reference USB A-Micro B uses our Ferrite insulation to reduce Jitter, as well as isolating the data and power lanes for a cleaner overall signal.
Triple magnet screening and 24K gold plugs makes our Performance USB A-Mini B the best in its class.
Connecting your mobile device/tablet to your audio system has never been easier with our 2 step 3.5mm jack for a simpler connection.
Using our in house HDMI testing facility, QED have designed premium HDMI cables to suit any budget. From our flexible and slimline profile to our exceptional Reference HDMI with its BandPass filter technology to reduce Jitter to Ultra low levels
For all of your Optical needs, QED has an optical cable for you. For the more advanced, high bandwidth signals, Reference Optical Quartz uses glass technology to accurately send the information from source to receiver.
The most common type of cable used for connecting products on a wired network. This cable connects wired devices together to the local network for file sharing and Internet access.
Using technologies from our analogue cables such as complimentary conductor technology, your subwoofer will always perform to its best capability.
Reference USB, the flagship USB cable representing the pinnacle of musical performance
Reference USB cable is designed to transmit high definition digital audio between USB audio components (such as a computer or storage device and a high performance DAC) with ultra low jitter. It utilises a carefully engineered geometry including an integral Ferrite jacket, electrically isolated power conductors and an impedance controlled data lane to reduce timing errors within the digital signal, for cleaner audio transmission.
QED Reference USB features an integral Zn/Mn floating ferrite jacket. When measured using an eye pattern generator at the correct data rate for high bandwidth USB, the cable exhibits 50% less jitter than competitor cables without the ferrite jacket. Our findings indicate that ultra low jitter in an isochronous data stream results in an audible improvement in sound quality. Certainly, in listening tests, the Reference cable with the ferrite jacket was preferred to samples without the jacket.
Five nines oxygen free copper conductors, LDPE dielectrics and legendary build quality combine to create audible sonic improvements. Our extensive listening tests comparing competitor products at much higher price points have astonished us! We urge you to compare Reference USB not only to your current favourite cable but also alternative brands and models at any price!
QED Reference USB uses a tightly controlled 24 AWG 99.999% OFC twisted pair which is bound by an aluminium mylar wrap with a drain wire pulled underneath. This arrangement is identical to that used in our high performance HDMI cables and is not usually found in a USB cable. Because the impedance of the data lane is kept strictly within defined limits, the jitter added to the data stream is kept to a minimum.
Many audio enthusiasts feel that USB power cables carrying charging currents and PC power supply spikes near to the isochronous serial data stream can have an adverse affect on sound quality. One answer is to remove the power cables altogether but this deviates from the USB spec and can cause inconvenience especially if the DAC electronics require USB power. QED Reference data lanes are uniquely electrically isolated by using a double layer shield comprising a 100% aluminium mylar wrap and drain wire connected to ground.

Während konventionelle Stecker die Vorteile unserer sorgfältig entwickelten und gefertigten Kabel – wie ein Ferrari mit Holzrädern – schnell zunichte machen, übertragen die Anamate und Analoc Cinchstecker das Audiosignal über den gesamten Transportweg in bester Qualität.
Als Jitter bezeichnet man zeitliche Abweichungen bei der Übertragung von Digitalsignalen in der Elektronik und Telekommunikation, oft in Bezug auf einen Referenz-Taktgeber. Ein USB-Kabel mit einem Messwert von 12 ps weist einen extrem geringen Jitter auf.
