What Hi-fi? Accessories Product of the Year 2016!
Award-winning shielded speaker cable based on Carnival SilverScreen. FEP insulation has same electrical characteristics as PTFE. Conductor insulation can cause colouration of the signal. Using FEP on Clearway allows us to produce a cable with very little colouration, whilst the dual layer shielding offers a high degree of protection from interference. This is a really good speaker cable given its cost. It carries signals extremely accurately and will work over long runs. Suitable for all grades of hi-fi systems and home cinema systems.
During the development of Clearway, valuable research was carried out in relation to the behaviour of conductors and different dielectrics (insulation). For a long time, we have understood the importance of the relationship between conductor materials and insulation, and its silver-plated speaker cables make extensive use of PTFE as an insulation material.
The type of insulation doesn’t just affect a cable’s ability to carry signals accurately, it also has an effect on the tonal characteristics that the cable brings to the system. This often takes the form of an unwanted increase in bass frequencies, which directly limits a system’s ability to produce music with coherence and involvement.
Typically, cables that use oxygen-free copper as a conductor material will use either polyethylene or PVC as an insulating material. What sets The Chord Company’s Clearway speaker cable apart is its use of FEP: a derivative of PTFE with very similar performance characteristics. Compared to polyethylene, the FEP-insulated Clearway carries both detail and dynamic information markedly more accurately. The tonal properties of the cable are also considerably more neutral.
The FEP-insulated conductors are built from multi-strand oxygen-free copper and are arranged in a twisted-pair configuration to reduce interference. The two conductors are then protected with a layer of soft PVC (which was chosen over polyethylene because of its flexibility), in order to correctly space the shielding in relation to the conductors and to minimise any mechanically induced noice.
High-performance shielding is specified and just like the award-winning Carnival SilverScreen, Chord Clearway speaker cable features two contra-wound high-density foil shields. Like many Chord speaker cables, the twin foils, combined with the twisted-pair configuration, make for a level of shielding that is effective to high frequencies. Finally, a clear protective PVC jacket is applied, which again serves to further reduce any mechanically induced noise.
Nigel Finn, Technical Director of The Chord Company on Clearway
“I am particularly pleased with the new Clearway. The cable has qualities that would normally be associated with considerably more expensive cables. The use of high-quality oxygen-free copper FEP insulation and high-density foil shielding means that at £10, it will be pretty hard to produce a better-performing speaker cable. Chord has tested the cable in all levels of systems and in every case, whether entry-level or high-end, the levels of clarity, detail, dynamics and critically, musical coherence, are really impressive.”
