Description

In common with all our cables, the QED Reference Hi-Res USB Cable is informed by the results of our research into cable design, which began in 1995 and was recently detailed in the updated Genesis Report. 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 featuring low-permittivity, foamed polyethylene dielectricsย uniformly bound by an aluminium/mylar wrap. This increases the enjoyment of listening to music conveyed by the cable to an extent large enough for it 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 jacket.

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 upon 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.

The distortion is similar to a subtle version of the more familiar THD present in many amplifiers. This problem inevitably increases listener fatigue making the music sound harsh or just simply not enjoyable.

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