Reference 75-Ohm Digital Precision | Available at Trimira Audio
The Nordost Valhalla 2 75-Ohm Digital Interconnect is a flagship digital coaxial cable from Nordost's Reference Series, engineered specifically for 75-ohm digital interfaces such as S/PDIF.
Its construction combines Dual Mono-Filament technology, a heavy-gauge silver-plated solid-core OFC conductor, comprehensive shielding, carefully controlled coaxial geometry, and proprietary HOLO:PLUG® BNC terminations.
At Trimira Audio, we recommend the Valhalla 2 75-Ohm Digital Interconnect for reference digital systems connecting CD transports, network streamers, digital bridges, DACs, and digital processors.
Key Features & Technological Innovations
Patented Dual Mono-Filament Technology
The solid-core conductor is wrapped with two helical FEP strands before the outer FEP jacket is applied.
This creates a low-contact dielectric environment designed to minimize dielectric interaction and energy storage while supporting rapid signal propagation.
Heavy-Gauge 16 AWG Solid-Core OFC
The Valhalla 2 75-ohm version uses 1 × 16 AWG solid-core conductor manufactured from 99.999999% high-purity OFC copper with 85 µm pure silver plating.
The solid-core construction provides consistent conductor geometry throughout the coaxial signal path.
100% Dual-Layer Shielding
A combined foil-and-braid structure provides 100% total coverage, protecting the high-frequency digital signal against:
- RF interference
- Electromagnetic interference
- External electrical noise
- High-frequency crosstalk
Strict 75-Ohm Characteristic Impedance
The cable is specifically engineered around a true 75-ohm characteristic impedance, making it appropriate for 75-ohm digital interfaces.
Maintaining consistent impedance helps minimize electrical reflections within the digital transmission path.
Custom HOLO:PLUG® 75-Ohm BNC Terminations
The cable is terminated with custom 75-ohm HOLO:PLUG® BNC connectors.
Gold-plated 75-ohm BNC-to-RCA adapters are supplied for components equipped with RCA-type S/PDIF connections.

Why 75 Ω Matters
The 75-ohm version should be selected for digital interfaces designed around 75-ohm coaxial transmission, such as conventional S/PDIF.
It should not be confused with 110-ohm AES/EBU, which uses a different balanced transmission architecture and requires a dedicated 110-ohm cable.
