Revisiting the foundation of sound—Grandio AC-1, at 6.0 m.
【ZONOTONE Grandio AC-1 (6.0m) Interconnect Cable】
For your car audio sound, you may want a little more power and more information. You want to bring out even the subtle nuances in vocals and instruments—naturally. If that’s what you’re looking for, consider ZONOTONE’s Grandio AC-1.
This interconnect cable combines five materials centered around ultra-high-purity 7N-class Cu: the new-material high-performance pure copper wire HiFC, the high-purity oxygen-free copper wire PCUHD, tinned OFC, and high-purity oxygen-free copper. Not only does it deliver power, it also expresses the leading edge of sound, resolution, and delicate details in a well-balanced way—adding depth and breadth to the soundstage.
You may notice the presence of vocals you always listen to becoming stronger, and the positional relationships of instruments becoming easier to understand. It’s not about simply making the sound flashy; it’s for those who want to receive the information of the entire music more naturally. Since the cable length is 6.0m, it’s also an easy option to consider even when the distance between components is longer depending on your vehicle’s system layout.
With interconnect cables, impressions can vary not only based on the performance of the product itself, but also on the compatibility with the equipment you connect, how the wiring is routed, and the overall sound balance of the system. At LOGON, we consider together not only your current car audio configuration and the sound you’re aiming for, but also where you should replace cables and how to pair it with other cables.
If you have specific concerns—such as “I want the core of the sound to come out a bit more,” “I want to refine the fine expression in the treble,” or “I want the entire system to sound a step more composed”—we’ll guide you according to your needs. Feel free to consult us once, without forcing a decision, including how much change you can expect from a cable replacement.
