6NAC-Granster 3000α (2.5m)

A high-quality cable that connects with care to every detail of the music.

【Zonotone 6NAC-Granster 3000α (2.5 m) | High-End Audio Cable with High-Purity Conductors】

If you want to increase the amount of sonic information and bring out even the smallest details clearly, this is the high-end audio cable from Zonotone for you.

6NAC-Granster 3000α uses a hybrid design that combines four types of conductors, centered on ultra-high-purity 6NCu, along with high-purity oxygen-free copper wire “PCUHD” and high-performance pure copper wire “HiFC,” among others. With a four-core double-shield structure, it delivers music signals with stability while extracting subtle sonic nuances and strong drive.

When you actually listen to music, you’ll find that information that may have been slightly buried up to now becomes easier to notice—such as vocal expressions, the spatial relationship of instruments, and the leading edge of sound. Rather than simply making the sound flashy, it’s well-suited for those who want to enjoy Zonotone’s signature “Pure & Power” while improving the overall clarity and perspective of the music.

This class also supports balanced transmission for the first time, making it suitable for use in combination with compatible high-end AV amplifiers.

When using it in a car audio system, it’s important to consider not only the cable’s performance on its own, but also compatibility with the amplifier and speakers, your existing system, and even cable routing. Even with the same cable, the impression of the final result can change depending on where and how it is integrated.

If it were me, I would recommend it to people who have already set the overall direction of their system and want to raise the sonic density and amount of information by another step. Let’s go through it together while checking your vehicle and system configuration, to see which parts are truly worth upgrading.
