Atlas' ‘ultimate’ speaker cable. Performance without compromise. A reference class pure silver speaker cable engineered for the world’s finest audio systems. Asimi uses very high purity OCC (Ohno Continuous Casting) silver conductors.
The OCC process is named after professor Atsumi Ohno, who in the late 1970s, discovered that by heating the drawing mould to a higher temperature than the molten copper you intend to cast, then cooling it soon after, the result is one long, high purity (99.99997%) metal crystal. Criticism of silver cables as generally ‘bright’ are in fact the result of impurities and grain in the inferior conductors used.
The Asimi’s high-purity monocrystal conductors are arranged in a complex multi-stranded layout, with each cable leg composed of 3 pairs of solid conductors each of different diameter, totalling 3.5mm² – an unusually high figure, given the cost of this purity of silver. In most silver cables, the conductor size is compromised to reduce cost –but which explains why some critics suggest silver cables offer the listener very sweet highs but no weight or authority at low frequencies. That’s certainly not true of the Asimi, with several reviewers commenting on the sense of physical presence conveyed.
Atlas' focus was also on the coating that insulates and protects the silver. The Asimi has these conductors enveloped in our microporous Teflon dielectric. This new air-spaced material improves on the performance of the best solid Teflon or PTFE (Teflon™) insulators, by providing a 30% greater signal velocity and superior integrity, particularly in high frequency delivery. This is achieved because the new material has a dielectric constant of around 1.5 (the lower the number the better), significantly better than the 2.1 typically achieved by the PTFE (Teflon™) insulators which were previously the best available in these applications.
This obsessive attention to detail – and the combination of materials & assembly methods which was only finalised after exhaustive testing – produces a cable which HiFi World’s reviewer described as‘ the best he’d ever heard’ and HiFi Plus summarised as ‘one of the very, very best.’
Atlas' goal to make cables which have no discernable character or sound of their own, which would in itself be a form of distortion – Asimi is engineered to ‘disappear’ in your system, conveying the performance of your equipment with total transparency.
It should be noted though that Asimi requires a ‘burn-in’ period during which the sound will continue to improve.
The Transpose is a modular, cold-weld, air-tight, solder-free speaker plug. Interchangeable connector options are spade, Z-plug and expanding plug, available in gold or silver.
In a cold-weld connection, the metal of the connector plug and the wire are squeezed together under a calibrated pressure to form a robust, consistent, air-tight metal to metal contact with no damage to the cable dielectric. The result is a smooth, uninterrupted signal path which behaves as one continuous entity, with minimal degradation of the signal compared to soldered connections.
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.’ 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.
Silver, with its lower resistivity, is a better conductor than copper, but any conductor, whether silver or copper, must have a reasonable cross-sectional area when used for audio applications. Silver is much more expensive than copper and, in order to keep costs within reason, the cross sectional area of silver audio cables are often compromised and the resulting sound is ‘bass light.’ Good silver cables are, however, fast, dynamic and seamless through the audio spectrum and provide exceptional detail and instrument resolution. The Atlas Asimi cables employ OCC silver conductors and in the case of the Asimi speaker cable, these are a substantial 3.5 sq mm in overall size in order to provide wide bandwidth and superior definition.
PVC (Poly Vinyl Chloride) is cheap to produce and, as such, is the most commonly used insulation in AV cables. However, PVC is the worst quality insulation a Hi-Fi or AV signal can encounter as its high loss causes a significant reduction in signal velocity. PVC is better suited to power cables and should be avoided in Hi-Fi and AV signal cables.
Other dielectrics in common use are Polyethylene, Polypropylene and Polytetrafluoride Epoxy (better known as PTFE (Teflon™) or Teflon,) and the new and unique Atlas (PTFE).
Microporous PTFE (Teflon™) is a unique, low density dielectric material, phase stable at room temperature, which offers significant performance improvements over solid PTFE (Teflon™) dielectric designs.
The table below shows the properties of a selection of dielectrics. Though not used as a dielectric in Atlas' cables, PVC is included for comparison purposes.

Atlas Cables are a major producer of interconnects and cables in the United Kingdom of Great Britain. All products are researched, developed and most are assembled in the Atlas purpose built factory in Scotland.
Many of these products are unique and use advanced techniques of production or manufacture in order to bring to the user the very finest quality products. With each new model we continue to push the boundaries of reliability and performance. It's little wonder then, that Atlas Cables have had so many mile-stone advances in the past and that Atlas Cables have secured so many awards in comparative tests against other products.
