Know before you buy
No, the Grand Activation AC-55 is sold as a bulk cable. You will need to purchase and install your own preferred AC connectors to complete the assembly.
MMAT is a proprietary treatment applied to the OCC copper conductors. It is designed to optimize signal flow and reduce noise, resulting in a cleaner, more refined sound profile for your audio equipment.
While the 10-gauge OCC copper and cotton insulation provide a robust build, the cable is relatively stiff due to its thickness. It is best suited for runs where you do not need to make extremely sharp, tight-radius bends.
Cotton is used as a dielectric material because it offers excellent vibration damping and helps minimize static buildup. It provides a natural, non-reactive environment for the conductors compared to standard synthetic plastics.
Yes, the 10-gauge conductor size is well-suited for high-current applications. It is engineered to deliver stable, unrestricted power to demanding audio components like power amplifiers or large integrated systems.
