A Sophisticated speaker cable offering a true taste of ‘high-end ’ performance for discerning audiophiles.
Ascent is the first speaker cable in our product hierarchy to use OCC (Ohno Continous Casting) copper connectors with a total 3.5mm² diameter. The increased conductor cross-section gives superior low-frequency performance in comparison to Ascent 2.0. These ultra high purity ‘6N’ (99.99997% purity) conductors are extremely transparent to the signal being passed, their mono-crystal structure ensuring minimum signal loss. For the dielectric, we use a high-efficiency PTFE (Teflon™) which again imposes virtually no signal degradation.
In conjunction with our cold-weld, wideband Transpose connectors, which give a superior connection to conventional solder or screw fixing, the result is a cable with little discernable character which allows your system to convey a level of detail, speed and dynamics which might well surprise you.
About Ohno Continuous Casting copper (OCC copper)
In 1985, Professor Ohno, from the Chiba Institute of Technology, developed his patented method for the extrusion of a grain-free copper wire. (Technical papers are available from the Japan Inst. Metals and from Chapman & Hall, publishers.)
When a pure metal solidifies, its crystals grow in a specific geometrical pattern (typical to that metal) emanating from a nucleus, rather like the dendritic growth pattern of a tree. The size of the metal crystals grown can be varied by repeatedly annealing metal such as is done in the LC-OFC process. The structure of a strand of copper may be likened to that of a bag of sugar. Every grain of sugar has a crystal boundary. In a conductor, these crystal boundaries (potential barriers) act as a non-linear resistance to the flow of electric current. It follows that, the fewer the boundaries, the less the effect there is on an electric signal as it propagates from one end of the conductor to the other. Atlas cables such as the Mavros and Ascent use OCC copper, whereas the top of the range Asimi uses pure OCC silver.
The Ohno continuous casting method re-heats the extrusion as the molten copper is forced out of the mould and very slowly and gradually draws the grain or crystal down the conductor''s length, creating a ‘single crystal structure.’ Actually, because no copper is 100% pure, there will always be a few boundaries produced by impurities. The frequency of boundaries created are quite insignificant. A typical crystal in a copper conductor drawn to 0.3 mm diam. using the OCC process is 125.00 metres long!
The benefits are obvious, with almost no crystal boundaries, the audio signal is no longer impeded down the copper wire and more information and detail is delivered faithfully to the receiving equipment.
