QED's Reference series is the penultimate range of interconnects in their extensive catalogue. Featuring an entirely new design concept, the cordage of the Reference models are designed first and foremost for low capacitance. This is because QED have identified this factor as being a significant player in the high fidelity listening experience, by retaining a low capacitance, sound signals are better looked after and allow for a more collected and detailed hifi performance.

The Reference range also utilises QED's 'Complementary Conductor Technology' to ensure a high frequency detail, and their Analoc Technology to optimise signal integrity. All QED interconnects and cables feature a lifetime warranty, including the Reference series.

QED Reference Optical Interconnect is a suitable upgrade to allow your Hi-Fi or Home Cinema to benefit from the sound quality and practicalities of digital formats.

This will connect a wide range of both Hi-Fi and Home Cinema audio products to each other. Many CD players, Minidisc players and some DAT recorders feature the digital optical connection, and with QED Reference Optical Digital interconnects, you can take advantage of the pure digital quality of sound that these machines produce by linking them to your amplifier, provided it also has digital interconnect inputs. In Home Cinema, your DVD, Blu-ray, Lazer Disc, games console or Digital Set-top Box components an be connected to your digital interconnect compatible surround amplifier or processor.

It is easy to see why QED has the advantage over similar priced interconnects from other brands. PMMA acrylic glass plastic optical fibres and graded refractive index ensure reduction in transmission and data losses. Whilst 24K gold connectors, with precision engineered plugs incorporating strain reliefs and fluorinated polymer cladding materials for ultimate reliability in the most demanding systems.
