With a vast array of technologies and our 40+ years in the specialist cable market, we produce cables to suit every budget to maximise the potential of your beloved system.
DIGITAL
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.
PHONO TO PHONO
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.
XLR
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.
DIGITAL COAXIAL
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.
USB A-B
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.
USB A-B MICRO
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.
USB A-MINI B
Triple magnet screening and 24K gold plugs makes our Performance USB A-Mini B the best in its class.
JACK TO PHONO
Connecting your mobile device/tablet to your audio system has never been easier with our 2 step 3.5mm jack for a simpler connection.
HDMI
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
OPTICAL
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.
ETHERNET
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.
SUBWOOFER CABLE
Using technologies from our analogue cables such as complimentary conductor technology, your subwoofer will always perform to its best capability.
PERFORMANCE
Subwoofer
Give Your Bass the Signal it Deserves
Adding a subwoofer should make a system sound bigger, deeper and more immersive. It shouldn't introduce hum, noise or another round of second-guessing.
Performance Subwoofer is designed to make the connection between your amplifier and active subwoofer simple, reliable and engineered for musical accuracy.
Built around QED's proven Solid Complementary Conductor™ Technology, it helps preserve signal timing and integrity while advanced shielding technology protects delicate low-frequency signals from the electrical noise found in modern homes.
Whether you're adding a subwoofer to a stereo system, expanding a home cinema setup or finally giving your speakers the low-frequency support they deserve, Performance Subwoofer gives you the confidence that this vital connection is properly taken care of.
Designed for Low-Frequency Precision
A subwoofer does more than add weight to explosions and basslines. Done properly, it adds scale, texture and authority to music and movies alike.
The challenge is preserving the low-level analogue signal travelling between amplifier and subwoofer while preventing unwanted noise from finding its way into the system.
Solid Complementary Conductor™ Technology
Performance Subwoofer uses two electrically isolated solid-core conductors made from 99.999% oxygen-free copper. The differing conductor diameters are designed to help reduce timing errors and maintain signal accuracy throughout the audio pathway.
The result is bass that sounds more controlled, more detailed and better integrated with the rest of your system.
Built for the Real World
Modern living rooms are packed with potential sources of interference. TVs, Wi-Fi routers, games consoles, switching power supplies and smart home devices all generate electrical noise.
Performance Subwoofer combines dual electrostatic screening with QED Ferrite Insulation Technology™ to help protect the signal from unwanted RF and digital interference before it reaches your subwoofer.
Less noise. Less distraction. More music.
Flexible Where it Matters
Subwoofers rarely sit conveniently next to the amplifier.
That's why Performance Subwoofer uses an ultra-flexible TPE outer jacket that makes routing and installation easier, while helping reduce handling noise during setup. Gold-plated QED phono connectors ensure a reliable, high-conductivity connection designed to last for years.
