【Grandio AC-1 (5.0m)｜Interconnect Cable That Draws Out the Depth of Music】

The Grandio AC-1 (5.0m) interconnect cable by Zonotone is chosen by those who want to enjoy car audio one step deeper.

Cables may not be an eye-catching component, but they are an important part that connects equipment such as the head unit, DSP, and amplifier. If you want to deliver music information properly, it’s essential to consider not only the components themselves, but also the cables that link them.

At the core of the Grandio AC-1 is ultra-high-purity 7N-class Cu, and it employs five types of materials: a new high-performance pure copper wire (HiFC), a high-purity oxygen-free copper wire (PCUHD), tin-plated OFC, and ultra-high-purity oxygen-free copper. By combining these materials using Zonotone’s unique balance, it doesn’t lean only toward power— it expresses the liveliness of the sound, resolution, and even delicate details.

Its appeal is that sounds which may have felt a bit “all in one” until now—such as subtle vocal nuances, overlapping instrument tones, and the spread of the soundstage—become easier to perceive with depth and a three-dimensional sense. When you revisit your usual songs, you may also find moments where you notice, “So that sound was in there too.”

However, when replacing cables, it’s important to choose based on compatibility with your entire current system rather than thinking about the cable in isolation. Depending on the sound direction, cable length, and how your devices are connected, the best-matching cable can change.

At LOGON, we guide you according to your sound preferences and budget while checking your vehicle model and the head unit, DSP, and amplifier you’re using. If it were me, I wouldn’t decide only the cable first. I’d listen to the parts you’re currently concerned about, and then organize—together—which locations to replace and in what priority order.

If you’d like to raise the amount of musical information and spatial expression a little while making the most of your current system, please feel free to consult us. Let’s consider the direction in a practical way as we confirm the real sound inside your car.
