QED Performance USB A to USB B Lead

The QED Performance USB A to USB B Lead is a speciality cord used to connect audio equipment to digital devices. It is ideal for individuals with high audio requirements who need a stable transfer between a computer and USB DACS. This cable manifests ‘natural’ sound and ‘useful’ form.

QED Performance USB A to USB B Lead

The QED Performance USB A to USB B Lead is designed to transmit high-definition digital audio between USB audio components. Performance USB cable transmits high-definition digital audio between USB audio components (such as a computer or storage device and a high-performance DAC) with very low jitter.

At QED, we have identified that reducing jitter or timing errors within the digital signal makes for cleaner audio transmission, and with USB, this is no different. Triple magnetic screening ensures enhanced signal protection and 24k gold-plated connectors for improved signal transfer.

24k Gold Plated Shielded Connectors

The Performance USB lead uses 24K gold-plated connectors to ensure a seamless connection and secure fit. The Performance USB A to B lead follows the USB 2.0 specification for high-speed data transmission, making it ideal for HD Audio DAC applications up to 24-bit 192kHz.

Very Low Jitter

Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often concerning a reference clock source. A Performance USB lead displaying very low jitter is typically measured at 21 ps rms.

Improves Audio Clarity

Specifically engineered for this USB cable is the minimisation of electronic noise. This not only clears out sound distortions but also frees up the sound signal in transit from the digital to the audio devices. Everyone, be it an audiophile or a sound engineer, would consider it a significant advantage.

Built to Last, and Dependable

The USB lead by QED is made for extended usage, so you are less likely to experience any issues. The materials the cable comprises do not corrode easily, as they are of high-grade quality and resistance. As a result, the cable will be a part of your audio environment for a relatively longer time while guaranteeing sturdy and permanent connections without degrading your devices.

Easily Movable and Handy

The product’s pliability allows it to be moved and adapted to many situations, e.g., set up at home or in a professional studio. It does not twine and is quite convenient; thus, the equipment’s setup becomes very fast and straightforward.
