Shunyata Research Theta NR: Elevating Power Cable Performance
The Shunyata Research THETA NR power cable is a meticulously crafted high-performance solution designed to elevate the sound quality of high-end audio systems. Positioned as an upgrade to the highly regarded Delta NR, the Theta NR offers superior performance while maintaining an accessible price point, making it a compelling choice for audiophiles seeking exceptional value.
At the heart of its design are Shunyata's proprietary VTX™ (hollow core) and VTX-Ag™ (silver-core) conductors, encased in ultra-pure OFE copper to optimise signal transmission. These advanced materials and construction techniques deliver extraordinary sonic clarity, dynamic precision, and a noise-free background that enhances every nuance of your listening experience.
Key Features and Innovations
VTX™ and VTX-Ag™ Conductors: Combining hollow-core technology with pure silver and ultra-pure copper, these conductors offer unparalleled signal transmission, balancing warmth, precision, and clarity.
KPIP v2™ Conditioning Process: A proprietary four-day molecular refinement process that enhances the cable's dynamics, frequency extension, and overall coherence.
Room-Filling Soundstage: With larger gauge conductors, the Theta NR delivers weight, dimensionality, and a vast soundstage that immerses the listener.
Advanced Noise Reduction: Effectively reduces power-line noise, allowing your system to perform at its peak without unwanted distortion.
Two distinct models to choose from:
THETA NR
The Shunyata Theta NR delivers clean, noise-reduced power to upstream components like power conditioners and generators. Using NR (Noise Reduction) Technology with multi-stage filters, it minimises power-line and component noise, enhancing clarity, dynamics, and soundstage. By eliminating noise, it boosts the performance of connected devices, ensuring optimal system-wide audio quality.
The Shunyata Theta XC power cable is designed for high-current components, delivering continuous, unrestricted power without noise reduction. Featuring XC (eXtra Current) Technology, it ensures amplifiers and demanding equipment receive the energy needed for optimal performance, enhancing timing, dynamics, and control. Ideal for downstream use, it pairs perfectly with the Theta NR for upstream conditioning to maximise system performance.
Performance Highlights
The Theta NR power cable transforms high-end systems by unlocking new levels of detail, coherence, and musicality. Its ability to handle complex dynamic shifts effortlessly results in explosive dynamics and precise frequency extension, rivaling cables at significantly higher price points. Theta NR’s performance enhances transient response, creating a sense of immediacy and natural flow that breathes life into music.
Whether it’s intricate textures or room-shaking bass, the Theta NR refines your system’s capabilities to deliver an emotionally engaging experience.
The Theta Series Legacy
Shunyata Research’s Theta Series, including signal, digital, and power cables, embodies the scientific innovation that has earned Shunyata a trusted role in the world’s top recording studios and critical medical applications. Every element of the Theta Series—from its continuous-cast Ohno copper conductors to its fluorocarbon dielectric shielding—is precision-engineered to expand the boundaries of signal resolution and noise reduction.
PMZ (Precision Matched Impedance) Process: Ensures perfect conductor surface and dielectric tolerances, optimising shield placement for unmatched precision.
Slow Extrusion and Braiding Techniques: Machines operate at one-quarter speed during manufacturing to ensure exacting specifications and superior performance.
Custom Connectors and Terminations: Cold-soldered terminals and bespoke designs ensure reliability and peak conductivity.
The Theta Sound
Theta cables integrate seamlessly into any high-end system, allowing it to articulate dynamic shifts in timing, frequency, and textural nuance with remarkable precision. The absence of perceived noise unveils spectral and tonal subtleties, delivering explosive dynamics and natural coherence. With their larger VTX™ conductors, Theta cables provide added weight, dimensionality, and an expansive soundstage that transforms listening into an immersive experience.
The Theta NR power cable doesn’t just connect your system to power—it connects you to your music in a way that feels alive, immediate, and emotionally captivating. For those seeking to transcend the ordinary, the Theta NR sets a new standard for performance in its class.

Shunyata’s VTX-Ag™ cables feature a pure silver inner conductor and a pure copper outer concentric ring. This design combines the speed and clarity of silver with the warmth and powerful low-frequency performance of copper, avoiding their typical drawbacks. With premium fluorocarbon insulation to reduce dielectric absorption, VTX-Ag delivers exceptional resolution and clarity, exemplifying a balance of precision and musicality in cable performance.
ArNi® is a proprietary wire developed by Shunyata Research, designed to deliver unparalleled performance for audio applications. It begins with the purest copper available—OFE C10100 or Ohno (single crystal)—and is formed into virtual hollow tubes to eliminate skin effects and eddy current distortions. Premium fluorocarbon insulation further enhances performance by minimising dielectric absorption and re-radiation, significantly improving resolution and clarity. To maximise its sonic capabilities, the wire undergoes Shunyata’s proprietary KPIP™ V2 process.
Shunyata Research uses only the highest-purity copper for its wire products. OFE Alloy 101 (C10100) is the pinnacle of copper quality, boasting a minimum purity of 99.99% and a conductivity rating of 101% IACS. OFE stands for oxygen-free electrolytic, a standard that surpasses the older term OFHC (oxygen-free high conductivity). C10100 is the only copper grade accompanied by a written purity certification verified by ASTM F68 standards.
Fluorocarbon dielectrics are usually only found in wire used in the aerospace industry, satellites and only the most expensive audiophile cabling. It has special electrical characteristics; very low dielectric absorption, high dielectric strength and exceptional heat resistance. When used in audio and power cables is reduces the perception of dynamic compression and it improves sonic low-level resolution and clarity.
KPIP™ v2 (Kinetic Phase Inversion Process) is a technology developed by Caelin Gabriel after extensive research into phenomena like burn-in, wire directionality, and the effects of cryogenic treatment. Gabriel identified a core principle that burn-in and cryogenics only partially addressed. This discovery led to the creation of a processing technique and machine that virtually eliminates the need for both burn-in and cryogenic treatment.
