QED Performance Optical Graphite Cable

In Stock

The Performance Audio range from QED is the company's intermediate series of interconnects and cables. The Performance series borrows design philosophies from that of the higher-end Reference series, designed to offer the best possible audio signal transfer possible at this price point. A range of intricate and well-engineered technologies can be found with the Performance series, including quasi-balanced geometry and low capacitance dielectric materials. All QED interconnects and cables feature a lifetime warranty, including the Performance series.

The QED Performance Graphite Optical makes use of polymethyl methacrylate (PMMA) acrylic glass optical fibre, allowing for an accurate and quick signal transmission. The cable has been built to a 'very low jitter' design, resulting in a drastic reduction of digital errors, allowing for a cleaner audio data transfer and a superior listening experience. 

Directly connecting via digital optical automatically cuts out the need for extra circuitry, when using standard RCA to RCA phono analogue interconnects. Extra circuitry usually can make a small effect upon sound as there is more for audio signals to travel, building up more resistance in the process. Digital optical connection is straight out to input, then through a DAC (Digital to Analogue) converter of the receiving audio components – involving less circuitry in the process. The overall result is noticeable when looking for those detailed high-end and smooth, responsive low-end signals.

QED Performance Optical Digital is an ideal interconnect because of its great feature laden design. These features are as follows; medical grade fibre optic core, protective PVC jacket for safeguarding audio signals in transport from potentially harmful external influences (such as interference), 24k gold platted TOSLINK connectors and finishing touches in the form of a precision engineered plug with integrated grips on either end.
