Key Features
Pure Silver Conductors
High-purity solid silver for 6% higher conductivity and 1.5x faster electron drift than copper.
4-Fold Multicore
Four-conductor arrangement with overlapping magnetic field cancellation for low inductance.
Point-to-Point Air Helix
Air insulation from plug to plug, paired with silver's superior conductivity.
360 Degree Connectors
Three-axis rotation BFA banana and spade lug connectors with rhodium-coated contacts, pressure-grouted at 1.5 tonnes for a gas-tight, solder-free bond.
Technologies Inside
AIR Technology
Air is the perfect insulator.
Now in its fifth generation, AIR technology uses air as the primary dielectric instead of traditional plastics like PVC. Conductors run freely suspended through the cable via precision-engineered clips at defined intervals, reducing capacitance by approximately 83% compared to standard cables. The Point-to-Point Air Helix architecture extends this principle from connector to connector for almost loss-free signal transmission.
Cross Link Super Speed
Eliminating eddy currents at high frequencies.
Cross Link Super Speed waveguides are hand-threaded into the cable structure to prevent eddy current effects at high frequencies. This preserves the full detail and extension of the audio signal across the entire audible spectrum, ensuring transients remain sharp and high-frequency information arrives intact.
Multicore Architecture
Overlapping fields, lower inductance.
in-akustik's multicore conductor arrangements use four-fold structures where the overlapping magnetic fields of individual conductors deliberately cancel each other out. This reduces inductance and minimises the skin effect at high frequencies, delivering a more neutral, dynamic frequency response.
360 Degree Pressure-Grouted Connectors
Three-axis rotation. 1.5 tonnes of force. Zero solder.
in-akustik's 360-degree BFA banana and spade lug connectors move across three axes, making connection and disconnection effortless while preventing cable stress. Instead of soldering, which introduces additional metal alloys and weak points, each connector is pressure-grouted at 1.5 tonnes of force — creating a gas-tight, vibration-resistant bond. BFA bananas use beryllium copper with solid metal housings, while spade lugs use tellurium copper, both rhodium-coated for lasting conductivity and corrosion resistance.
AIR Helix Point-to-Point
Fifth-generation air insulation, from plug to plug.
The AIR Helix design suspends conductors in a helical arrangement through the cable using specially engineered clips at precise intervals. Air replaces traditional plastic insulation as the primary dielectric, reducing capacitance by approximately 83%. The fifth-generation Point-to-Point innovation extends this architecture from connector to connector, with specialised transitions for each plug-cable combination eliminating the last remaining sections of conventional insulation.
