Low-Noise Precision Transfer for Analogue Playback | Available at Trimira Audio
The Nordost Blue Heaven Tonearm Cable is a purpose-designed phono interconnect intended to preserve the extremely low-level signals generated by turntable cartridges.
Phono connections are particularly sensitive to electromagnetic interference, radio-frequency noise, mechanical vibration, and grounding problems. The Blue Heaven combines Nordost's Micro Mono-Filament technology, solid-core silver-plated OFC conductors, controlled twisted-pair geometry, and extensive shielding to create a carefully engineered signal path between tonearm and phono stage.
At Trimira Audio, we recommend the Blue Heaven Tonearm Cable for listeners seeking a dedicated, low-noise connection for high-performance turntables, tonearms, cartridges, and phono preamplifiers.
Key Features & Technological Innovations
Proprietary Micro Mono-Filament Construction
Each conductor is spiral-wrapped with a thin FEP filament before being enclosed in an extruded FEP jacket.
This creates a low-contact dielectric environment designed to minimize dielectric interaction and energy storage.
4 × 24 AWG Solid-Core Conductors
The cable uses four 24 AWG solid-core conductors made from high-purity OFC copper with silver plating.
Solid-core construction maintains consistent conductor geometry and avoids the strand interaction found in conventional braided conductors.
Twisted-Pair Low-Noise Geometry
The conductors are arranged in a precision twisted-pair configuration designed to improve common-mode noise rejection and minimize interference entering the sensitive phono signal path.
95% High-Coverage Braided Shielding
A 95% braided shield surrounds the signal conductors, providing protection against external:
- RF interference
- Electromagnetic interference
- Electrical noise
- Environmental interference
Dedicated Micro Mono-Filament Ground Wire
A separate, independently insulated ground conductor with spade termination provides a dedicated connection between the turntable/tonearm grounding point and phono stage.
Flexible Termination Options
The Blue Heaven Tonearm Cable can be configured with a variety of tonearm and phono-stage terminations, including:
- Straight 5-pin DIN
- 90-degree 5-pin DIN
- RCA
- XLR
- Gold-plated MoonGlo RCA
- Neutrik XLR
- Dedicated spade ground connection
Connector selection should be matched to the specific tonearm and phono-stage configuration.

The Nordost Blue Heaven Tonearm Cable is designed for the particularly demanding connection between a tonearm and phono stage, where low signal levels make appropriate shielding, grounding, and cable geometry especially important.
Trimira Audio can assist with:
- Confirming tonearm connector compatibility
- Straight versus right-angle DIN selection
- RCA versus balanced XLR configuration
- Ground-wire requirements
- Cartridge and phono-stage system matching
- Selecting the appropriate cable length
- Arranging an analog-system audition
For a carefully engineered phono connection, Blue Heaven combines Micro Mono-Filament construction, silver-plated solid-core OFC, twisted-pair geometry, 95% shielding, FEP insulation, and dedicated grounding in a purpose-built tonearm cable.
