The Pure Line Audio RedCore NoiseBlock Power Cable builds upon the uncompromising foundation of the RedCore, adding an advanced, integrated noise-management system designed to address one of the most overlooked issues in high-end audio: electromagnetic contamination traveling along the power line itself.
Every power cable acts like an antenna — inevitably capturing electromagnetic and radio-frequency interference from its surroundings.
The RedCore NoiseBlock is engineered to capture, absorb, and dissipate this unwanted energy before it reaches your audio components, preserving the purity of the power supply at the most critical point.
The result is power that is not only fast and stable — but fundamentally cleaner.
At the heart of the RedCore NoiseBlock lies a precision-tuned, inline NoiseBlock Module.
This passive system uses a proprietary blend of graphene layers and specially selected mineral compounds with piezo-electric properties.
As electromagnetic interference and static charges travel along the cable, the NoiseBlock:
Captures high-frequency noise
Converts unwanted energy into harmless mechanical dissipation
Stabilizes grounding by draining residual static electricity
Unlike traditional filters or conditioners, the NoiseBlock does not compress dynamics, restrict current, or alter tonal balance.
It works silently and continuously — allowing pure AC power to pass unimpeded while eliminating interference at the source.
By neutralizing static buildup and high-frequency noise, the RedCore NoiseBlock creates a more stable reference ground for your system.
This improved grounding integrity reduces micro-distortions caused by fluctuating noise potentials — resulting in a lower noise floor and a more relaxed, natural presentation.
Listeners consistently report:
Greater image stability and depth
Increased microdetail and low-level resolution
A calmer, more analog-like flow
Improved separation during complex passages
The music emerges from a darker silence — with more air, space, and emotional clarity.
The cable itself remains true to the RedCore DNA.
Solid-core OCC copper conductors, silver-plated for speed and conductivity, are arranged in a precision multi-braid geometry to maintain ultra-low inductance and resistance.
Electron velocity approaches 99% of the speed of light, ensuring instantaneous current delivery during dynamic peaks.
The NoiseBlock does not sit in the signal path - it operates alongside it - preserving the full dynamic authority and transient power that defines the RedCore sound.
To maintain absolute signal integrity, the RedCore NoiseBlock Power Cable features custom anti-magnetic aluminum connectors with gold-plated pure copper contacts.
These connectors reject magnetic interference while ensuring long-term stability, optimal conductivity, and a natural tonal balance free from glare or harshness.

Compared to the standard RedCore, the NoiseBlock version delivers greater silence between notes, improved spatial focus, and a more organic flow.
Bass gains texture and control, midrange becomes more expressive, and high frequencies extend effortlessly without edge or fatigue.
The system sounds calmer — yet more alive.
More revealing — yet more musical.
If RedCore delivers pure power,
RedCore NoiseBlock delivers pure power, purified.
Designed for listeners who have already optimized their systems and want to extract the final layer of realism, the RedCore NoiseBlock Power Cable addresses noise at its origin — before it can shape or mask the music.
Because in high-end audio, silence isn’t empty.
It’s where everything begins.

RedCore Power Cable
Best for: amplifiers and power-hungry systems that thrive on speed, punch, and dynamics.
Designed for dynamic systems that demand speed and energy. RedCore delivers fast current response, strong dynamics, and an open, engaging presentation — ideal for amplifiers and power-hungry components.
RedCore NoiseBlock Power Cable
Best for: electrically noisy rooms, complex setups, and systems that benefit from a lower noise floor.
Built on the RedCore architecture and enhanced with an integrated NoiseBlock module, this version actively captures and dissipates electromagnetic interference and static energy before it reaches your system. The result is a lower noise floor, improved clarity, and greater control — ideal for sensitive or electrically noisy environments.
GoldCore Power Cable
Best for: DACs, streamers, and revealing systems where tone, texture, and refinement matter most.
Focused on refinement and balance. GoldCore offers a smooth, natural tonal character with improved harmonic richness and control, making it a perfect match for DACs, streamers, and reference systems.
BlackCore Power Cable
Best for: reference systems chasing maximum silence, focus, and bass control.
Engineered for silence and control. BlackCore prioritizes noise rejection, ultra-low inductance and capacitance, and vibration damping to deliver the lowest noise floor, tighter bass, and a more focused soundstage.
CryoCore Silver Power Cable
Best for: reference systems where electromagnetic behavior, interface stability, and low-level system resolution are already limiting variables.
Built around counter-braided silver-plated OCC conductors and solid silver cryogenically treated connectors, CryoCore Silver is designed to control the electrical conditions under which components operate. Its geometry prioritizes electromagnetic field behavior rather than current capacity alone, making it particularly relevant in highly resolving systems where power-related interference, contact stability, and low-level masking become increasingly significant.
This power cable is designed to deliver stable, low-noise current
without restricting dynamics or tonal balance.
Performance will depend on component sensitivity, grounding,
and overall system resolution.
