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
J2J
Your Playlist Probably isn't the Weakest Link
From smartphones and tablets to portable music players and desktop systems, the humble 3.5mm connection is still everywhere.
The problem is that many of the cables connecting those devices to the rest of your system were treated as an afterthought long before they found their way into the box.
Performance J2J is designed to be a little more intentional.
Using individually screened oxygen-free copper conductors, low-loss dielectric materials and robust gold-plated connectors, it's engineered to transfer analogue audio accurately between devices, helping you hear more of your music and less of everything else.
Whether you're connecting a portable music player to an amplifier, a headphone output to active speakers or a desktop audio setup to your hi-fi, Performance J2J gives you the confidence that you've got this connection right.
Because convenience shouldn't mean compromise.
Designed for Analogue Audio
The signal leaving a headphone socket is relatively small and surprisingly vulnerable.
Electrical interference, crosstalk and noise can all affect what eventually reaches the amplifier.
Performance J2J is designed to help protect the signal throughout its journey.
Separate Channels. Better Isolation.
Performance J2J uses individually dual-screened 99.999% oxygen-free copper conductor pairs for the left and right channels.
The benefit is straightforward: improved stereo separation and better protection against unwanted noise finding its way into the music.
Low-Loss by Design
A foamed polyethylene dielectric helps minimise capacitance and creates a low-loss environment for analogue signals.
You could describe that in far more technical terms.
What's important is that the cable is designed to preserve the signal rather than get in its way.
Built for Everyday Use
Portable devices move around. Cables get bent, wrapped, unplugged and thrown into bags.
That's why Performance J2J uses an ultra-flexible TPE jacket to reduce handling noise and improve durability in everyday use.
The stepped profile of the gold-plated 3.5 mm connectors is also designed to work with modern phone cases, because removing your case every time you want to listen to music isn't anyone's idea of progress.
