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
USB C(M)-B(M)
USB. Minus the Headache.
USB has become one of the most popular ways to connect computers, streamers and music servers to DACs.
Simple in theory.
Until you start looking at cable specifications, data rates, shielding, certification logos and forum debates that somehow turn a straightforward connection into a weekend project.
Performance USB is designed to remove the guesswork.
Built specifically for digital audio, it combines USB-IF High Speed® certification, individually screened oxygen-free copper conductors and a low-loss cable design that's optimised for high-resolution audio playback.
Whether you're connecting a laptop, music server, streamer or DAC, Performance USB gives you the confidence that you've got this connection right.
Because your USB cable shouldn't become the most complicated component in your system.
Built for Digital Audio
Not all USB applications place the same demands on a cable.
Moving a spreadsheet to a printer is one thing. Delivering high-resolution digital audio to a DAC is another entirely.
Performance USB has been engineered specifically for audio applications, supporting high-resolution formats including 24-bit/192kHz audio and DSD512.
Certified to Perform
Performance USB is USB-IF High Speed® certified.
That certification isn't there for decoration.
It provides independent verification that the cable meets the standards required for reliable USB operation, giving you confidence that it will perform as intended with modern DACs, streamers and digital audio devices.
Protecting the Signal
Digital audio is particularly sensitive to timing accuracy.
Performance USB uses an individually screened 99.999% oxygen-free copper data lane alongside low-loss dielectric materials designed to help minimise interference and reduce the potential for cable-induced jitter.
You don't need to understand the engineering in detail.
What's important is that the cable is designed specifically to protect the audio signal, not simply move data from one place to another.
Keeping Power and Data Apart
Performance USB uses a triple-screened construction that keeps power conductors isolated from the data lane.
It sounds like a small detail, but good cable design is often a collection of small details working together to prevent problems before they happen.
The result is a cable engineered specifically for the demands of modern digital audio systems.
