Audio components (and specifically amplifiers) draw current in pulses. Depending on the output, too small a gauge of the power cable will result in excess resistance. The DH Labs Power Plus is a robust 12 AWG AC cable capable of supporting the most demanding current flow and signal dynamics, and its conductors consist of ultra high-purity Oxygen Free Continuous Crystal™ Copper (long grain), which are specifically effective for audio applications.
Power Plus Cryo
from $450.00
A 12 AWG cable with proprietary noise cancelling geometries, cryo-treated for lower noise and improved articulation
The DH Labs Power Plus is one of the best values on the market today.”

Noise rejection is another key factor in the design of an AC power cable. Power Plus is an un-shielded cable that features proprietary noise canceling geometries which help to cancel all levels of magnetic distortion. Cryogenically treating this cable lowers the noise floor even further while also articulating bass response and overall dynamic contrasts.
This AC cord was engineered in the USA for superior performance, and can be recommended for use in the finest audio and home theater systems.

Understanding Copper Grain Structure in Audio Cables
The term grain refers to the microscopic fractures or boundaries within the surface of copper. This matters because audio signals primarily travel along the surface of the conductor, and each grain boundary can introduce resistance and signal distortion.
Standard OFHC (Oxygen-Free High Conductivity) Copper – Commonly used in many audiophile-grade cables, this copper contains approximately 1,500 grains per foot.
Linear-Crystal or LC-OFC Copper – A higher grade of copper that has been carefully drawn to reduce grain boundaries, resulting in about 70 grains per foot. This refinement enhances conductivity and signal clarity.
Typical OHNO Copper (Offshore) – Produced using heated mold continuous casting, this process yields ultra-long, single-crystal copper grains—often up to 200 feet in length. It’s a step above in terms of signal purity and performance.
DH Labs Continuous Crystal™ Long-Grain Copper (Made in USA) – Our proprietary copper technology (available only in the USA) pushes performance even further, producing single copper crystals that extend well over 700 feet. With no grain boundaries, extremely low electrical resistance, and a high level of purity, this material represents the pinnacle of copper performance for high-end audio applications.
