Air Audio Services Premium Balanced Cable for Astell&Kern Players: PBC-220.1

Air Audio balanced cable for the Astell&Kern AK100 II, AK120 II and AK240 players. Highest quality materials and processes are used to offer this premium quality cable for your high quality portable DAP when used as a high-end source audio player in your home audio system.

DUE TO THE ASTELL AND KERN JACK PLUG HAVING BEEN DISCONTINUED, THIS CABLE IS NOW NOT AVAILABLE.

Air Audio single-ended and balanced cable systems for the Astell&Kern AK100 II, AK120 II and AK240 players are highest quality interconnects in each price band, allowing these high quality portable DAPs to be used as high-end source players by perfectly matching them to your home audio system.

To ensure your Astell&Kern offers the most faithful reproduction through to your audio system, Air Audio interconnects for Astell&Kern use the very best conductor materials, connectors and manufacturing processes.

Premium Balanced Option

This interconnect cable from Air Audio Components offers maximum resolution and neutrality, due to the highest quality UP-OCC stranded copper wire with PTFE (Teflon®) dielectric and Xhadow XLR connectors using silver plated oxygen free copper (OFC) connectors held in a PTFE insulating dielectric. All solder connections are made using silver loaded solder.

These handmade cables then undergo a cryogenic material de-stressing treatment (cold annealing at -195 degrees C) that further enhances their sound qualities.

This premium balanced cable will enhance your complete system, it offers superb performance and the highlights of this cable are purity of sound, wide bandwidth; fast response time and good tonal colour due to the ultra-pure copper wire and high quality connectors.

Why Air Audio uses UP-OCC wire

UP-OCC stands for Ultra-Pure Ohno Continuous Casting – a patented process for manufacturing wire that has virtually no impurities in it and the wires are drawn from one material crystal. This ‘single crystal’ cable has only 5 parts per million (PPM) of oxygen atoms in it, as opposed to the next best OFC cable which has 10 or more.

UP-OCC cable has the lowest electrical resistance offering rapid signal transfer, plus flexibility and fatigue resistance without impairing conductive characteristics over time. UP-OCC wire production is a slow manufacturing process and only supplied by a handful of foundries in the world, so its cost is high and only used in the very best audio cables.

Why is PTFE (polytetrafluoroethylene) the best wire insulation?

The unusual combination of chemical and physical properties of PTFE leads to a material which has an almost universal inertness, complete insolubility in all known solvents below 300°C, excellent thermal stability and unsurpassed electrical properties, including low dielectric loss, low dielectric constant and high dielectric strength. Furthermore, PTFE does not embrittle at very high or at very low temperatures. The perfect material to insulate wires carrying audio signals, it interferes least of all commercial insulating materials with the audio signal being carried by the wire.

Why cryogenically treat the made-up interconnect?

Deep cryogenic treatment is a process that slowly takes the components down to a temperature of -195 C, 'soaks' them for several hours at this temperature and then slowly brings them back up to ambient temperature.

At these very low temperatures the structure of the metal changes, offering a closer molecular bond in the material by leaching away of oxygen and other non-metallic atoms found between metallic crystalline structures (metals of all types). It is this effect of cryogenic treatment on non-ferrous metals that offers better audio performance (it is thought) – it's clear that this will affect solder to substrate interfaces and non-OCC connector materials, but it is less sure as to why it also has a beneficial effect on UP-OCC material, where there is almost no crystalline structure or impurities to start with – but it does.
