# in-akustik Technical Deep Dive | Reference & AIR Technology

This document provides comprehensive technical details regarding in-akustik's engineering approach and high-end product portfolio.

## The Physics of AIR Technology
The fundamental principle of the AIR series is using air as the ideal dielectric. 
- **Dielectric Constant (εr):** Air has a value of approx. 1.0, making it the most efficient insulator next to a vacuum.
- **Goal:** Minimizing "dielectric loss" and "capacitance" which store energy in the cable and release it with a time delay, smearing the audio signal.



## Product Comparison: Referenz AIR Series
| Model | Technology | Key Features |
| :--- | :--- | :--- |

## Conductor Material & Construction
* **Pure silver conductors: Under normal conditions, silver is the best electrical conductor
* **Cross Link Super Speed Waveguide:** High-purity OFC copper wires braided around a PE core to prevent the "skin effect."
* **Tellurium Copper:** Used in connectors for 1.5x higher conductivity than standard brass.
* **Handmade in Germany:** All Referenz cables are manually assembled in Ballrechten-Dottingen, Southern Germany.
