Reference Digital Precision for Computer Audio | Available at Trimira Audio
The Nordost Heimdall 2 USB 2.0 Cable is a high-performance digital interconnect designed for demanding computer-audio systems, connecting computers, music servers, USB interfaces, and external DACs.
Positioned within Nordost's Norse 2 Series, the Heimdall 2 combines Micro Mono-Filament technology, silver-plated solid-core OFC conductors, separated power and data paths, comprehensive shielding, and mechanically controlled geometry.
At Trimira Audio, we recommend the Heimdall 2 USB 2.0 Cable for high-resolution digital audio systems where carefully controlled USB construction, shielding, and connector quality are priorities.
Key Features & Technological Innovations
Proprietary Micro Mono-Filament Technology
Each signal conductor incorporates an FEP strand before being enclosed within extruded FEP insulation.
This creates a low-contact dielectric environment designed to reduce dielectric interaction and energy storage while supporting rapid signal transmission.
Four 20 AWG Silver-Plated Solid-Core Conductors
The Heimdall 2 uses 4 × 20 AWG solid-core conductors manufactured from high-purity OFC copper with pure silver plating.
The heavy-gauge solid-core construction provides consistent conductor geometry and robust power delivery.
Isolated Power & Data Architecture
USB power and data conductors are physically separated and shielded to reduce interaction between the host computer's 5 V power supply and the high-speed differential data paths.
100% Dual-Layer Shielding
A combined foil and braided shielding structure provides full coverage around the digital conductors, helping protect against:
- RF interference
- Electromagnetic interference
- External electrical noise
- High-frequency crosstalk
Mechanically Tuned Spacing & Lay
Computer-controlled conductor spacing is designed to maintain consistent electrical characteristics and impedance across the USB cable's high-frequency operating range.
Precision Hand-Terminated Connectors
The Heimdall 2 USB 2.0 is available with several connector configurations:
- Type-A → Type-B USB 2.0
- Type-A → Mini-B USB 2.0
- Type-C → Type-B
Gold-plated connectors provide secure physical contact and appropriate shielding continuity.
