QED Reference Hi-Res USB A-B Cable

The QED Reference Hi-Res USB A-B Cable is a superior-quality USB cable explicitly engineered for digital audio. It links digital audio sources such as PCS, laptops, and streamers to modern DACS (Digital-to-Analogue Converters), guaranteeing clear, error-free sound communication for music enthusiasts and audiophiles.

QED Reference Hi-Res USB A-B Cable

In common with all our cables, our research into cable design informs the QED Reference Hi-Res USB Cable. The QED Reference High-Resolution USB is a state-of-the-art offering and represents the height of our understanding of this complex cable.

Impedance Controlled Data Lane

QED Reference High Resolution USB uses a tightly controlled, 24 AWG, 99.999% oxygen-free copper twisted pair that boasts foamed polyethylene dielectrics with low permittivity. This increases the enjoyment of listening to music conveyed by the cable to an extent large enough to be statistically significant in listening tests conducted in our bespoke listening facilities.

Clean Path Audio Technology

Many audio fans feel that running Hi-Res USB power cables carrying charging currents and PC power supply noise alongside the audio data stream can adversely affect sound quality. QED Reference data lanes are uniquely electrically isolated using a double-layer shield comprising a 100% aluminium/mylar wrap and shield braid.

Ferrite Insulation Technology

QED Reference Hi-Res USB features a unique integral Zn/Mn floating, ferrite jacket. Using a proprietary process, QED distributes this radio-frequency absorbent material evenly throughout the cable using a specially impregnated inner coat.

It absorbs high-frequency noise signals generated both internally and externally. It creates a much quieter electrical environment in and around the cable to minimise jitter within the audio data stream.

High Resolution Audio

Depending on 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 Reference Hi-Res USB signal. This is due to the interaction of the required frequency with the frequency of the jitter, which produces harmonics that were not present in the original signal.

QED Reference High Resolution USB is ideal for Hi-Res audio applications simply due to its unrivalled jitter performance. As we have shown, this delivers a performance that is at once more musical and enjoyable and enables a relaxed and long-lasting listening session, leaving hi-fi enthusiasts eager to repeat the experience.

Optimised for High-Res Audio

This cable concentrates on introducing high resolution audio formats. It speaks to the heart of the creation very clearly, without interference or computer-generated errors. This wire allows you to listen to great music, precisely as the artist wanted it to be.

Premium Build Quality

The QED Reference Hi-Res USB A-B Cable is a high-grade electronic accessory made with the highest and most exacting standards. It is characterised by design elements such as silver-plated conductors and the triple-shielded system. This acts as a barrier to the signal from exterior sources of interference. Moreover, this design also conserves the originality of the data and contributes to the flawless listening effect.

Overview of the QED Reference Hi-Res USB A-B Cable

The high accuracy of the reproduction of a cable ensures that it can transfer data exactly. This is suitable for high-resolution music formats. The difference between the two is whether you are an audiophile or a casual listener; you will easily perceive the better sound.

Good in Quality and Durability

The way the build is done guarantees good performance for years to come. To avoid data loss, silver-plated copper and gold-plated connectors are recommended. The triple shielding blocks external noise, allowing the sound to be transparent during playback.

Integration in any Environment Made Easy

The cable’s design, which can be readily bent and shaped, enables it to be used effectively in any setting. Although it is quite elastic, such manufacturing allows it to be better associated with other parts. In both cases, it works well, whether the audio setups are for professional use or for home use.
