Phono-2405 AIR Pure Silver
Pure silver phono reference. 25 mm Air Helix.
The Phono-2405 AIR Pure Silver replaces every copper conductor with high-purity solid silver within the 25 mm Air Helix architecture. Silver's 6% higher conductivity and 1.5x faster electron drift translate directly to timing precision and detail retrieval at the microvolt signal levels a cartridge produces. All termination and socket combinations (SME-90°, SME straight, 5-pin DIN, RCA, XLR) are available across the Phono AIR range.

Key Features
Pure Silver Conductors
High-purity solid silver at 61.35 S/m conductivity — 6% superior to copper with 1.5x faster electron drift for enhanced detail at cartridge signal levels.
25 mm Air Helix Architecture
Same Referenz-grade air-dielectric construction as the copper version — silver conductors suspended in air by Point-to-Point clips.
Cross Link Super Speed Waveguides
Hand-threaded waveguides work in concert with silver's electron drift for exceptional transient response from vinyl.
Matched to Your Tonearm
RCA-to-RCA as standard. SME-90°, SME straight, 5-pin DIN, and XLR combinations all available — specify your tonearm connector when ordering.
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.
