Black Rhodium Duet DCT++ CS Speaker Cables
DUET DCT++ CS Single wire and DUET DCT++ CS BiWire are based on the design of the successful and the highly awarded TWIST (Hi-Fi Choice 5 star, Hi-Fi World 5 Globes and Hi-Fi World 'Best Loudspeaker Cable - Awards 2012) TWIRL (Hi-Fi Choice 5 star, Hi-Fi World 5 Globes) and SAMBA (Hi-Fi World 5 Globes).
Vibration Stabilising to Reduce Distortion
DUET DCT++ CS Single wire and DUET DCT++ CS BiWire feature the GN LEGACY VS-1 Vibration Stabiliser developed for the GN Legacy range of cables and introduced for the first time in the Athena DCT++ CS loudspeaker cable. The vibration stabiliser has been specially designed to reduce audible cable distortion in cables by limiting the effects of vibrations travelling through the conductor wires which can cause audible distortion to your music
Advanced Cryogenic and Crystal Sound Processing for a Superior, High Impact Sound.
DUET DCT++ CS Single wire and DUET DCT++ CS BiWire is treated with our advanced DCT++cryogenic processing treatment. This involves temperature processing above and below room temperature. The DCT++ process alters the molecular structure of the cable to improve uniformity. The benefits of this are everlasting and bring an improvement to every single aspect of the cables performance.
In addition to DUET DCT++ CS Single wire and DUET DCT++ CS BiWire are also treated with the Crystal Sound Process. The Crystal Sound process, which is applied to the cable following the completed DCT++ process, refocuses the outermost skin of the conductor. The result is that the surface of the conductor is more closely packed and regular, and has a continuity which aids conduction through removal of voids left by the drawing process.
The main benefits of the Crystal Sound process are that bass notes sound more powerful and refined (you will notice a smaller cable can give the same performance as a much larger cable) and other notes will have greater clarity in their sound.
Low Transient Phase Distortion through Innovative Design
DUET DCT++ CS Single wire and DUET DCT++ CS BiWire give very clear diction of a singer’s voice and separates musical instruments superbly through a dramatic reduction of ‘Transient Phase Distortion’.
‘Transient Phase Distortion’ is reduced by using thicker insulation than is usual in speaker cables, increasing the distance between conductors and thereby reducing the magnetic field seen in each conductor wire as a result of the magnetic field created by the current in the other conductor wire. The benefit in listening is a clearer and more open sound quality.
“Compared to many high-end cables whose bulk and rigidity (or fragility) seem contrived to make their installation as arduous as possible, Black Rhodium’s Duet DCT++ CS is a positive joy to hook up. But while the cable is unusually ‘bendable’ its sound has real spine – its bass powerful and robust while the treble is smooth rather than incisive or biting. Certainly one for the shortlist, the Duet’s warm quality is suited to sharp-sounding systems.”

Anti RFI / EMI Technology to Further Reduce Distortion.
DUET DCT++ CS Single wire and DUET DCT++ CS BiWire is continuously twisted along their length to prevent the cable acting as a loop aerial. A cable that is untwisted has a larger surface area, therefore has a greater ability to attract RFI/EMI signals generated from Radio, Wifi, Mobile Phones and even central heating systems.
Additional RFI/EMI filtering is also applied directly to the conductor wire. This prevents high frequency noise modulating the signal at either end of the cable.
Both of the treatments above are designed to further reduce the amount of audible distortion in the cable, allowing cleaner, clearer sounds to be generated from your equipment.
Advanced Manufacturing Techniques to Reduce Noise and Distortion
DUET DCT++ CS Single wire and DUET DCT++ CS BiWire uses two silver plated copper cores for positive and negative signal flows. These are connected in opposite directions. Our listening tests have shown when connected this way the noise floor between the musical notes lowers. This gives ‘blacker’ silences in the interval between musical notes and enhances reproduction of the musical edges and natural decays in music.
Silicone rubber insulation is used because its low dielectric loss ensures extremely low distortion due to dielectric absorption effects in which sound energy is absorbed in the insulation and released at a later interval of time to create highly audible time-smearing distortion.
High End Rhodium Plated Award Winning Connectors – A Cable Is Only Good When All The Parts Are The Very Best Around!
DUET DCT++ CS Single wire and DUET DCT++ CS BiWire is terminated with ultra-high quality Rhodium Plated ‘Universal’ Banana Plugs. The award winning (Hi-Fi Choice *****) ‘Universal’ plugs are used because they have been specially designed to accommodate cables of widely varying size, a feature that makes them eminently suitable for BiWire cables.
These plugs are exclusively treated with the DCT++ CS treatment to further deliver the benefits discussed earlier. DCT++ and Crystal Sound Treated Connectors CANNOT be purchased in any retail store, and are exclusively available on Black Rhodium terminated cables.
Rhodium plating is applied to the plugs to ensure a cleaner and less corroded contact is maintained between the plug and socket and its effect a much livelier and more exciting sound from the music.
