A single cable that delivers the true contours of your music straight to your car’s system.
【Zonotone Grandio AC-1 (2.0m) Interconnect Cable】
For those who want to enjoy car audio with even deeper, more powerful sound, this is Zonotone’s interconnect cable, Grandio AC-1 (2.0m).
Even if you can feel the thickness and momentum of the sound, the subtle nuances in the vocal performance and the relative positions of instruments may seem a bit blurred. In such cases, reviewing the cables can help bring out more of your system’s overall character.
Grandio AC-1 is an interconnect cable that combines five types of materials centered on ultra-high-purity 7N-class Cu: a newly developed high-function pure copper wire HiFC, high-purity oxygen-free copper wire PCUHD, tin-plated OFC, and high-purity oxygen-free copper.
While preserving power and liveliness, it carefully expresses the sound’s contours and fine details as well. You’ll find it easier to perceive the vocalist’s breath, the lingering resonance of instruments, and even the depth of the soundstage—so that your usual music sounds with a sense of three-dimensionality, as if it were being performed onstage.
However, it’s not simply a matter of replacing the cable with something expensive. Depending on compatibility with your current system—such as the head unit, DSP, and amplifier—and on which part you use it in, the sound changes and balance will vary.
At Logon, after confirming your vehicle’s system configuration and the frustrations you’re currently experiencing, we think together about whether there is a meaningful place to use the Grandio AC-1 (2.0m). This is a cable suited for those who want to compensate for what your current system lacks and shape it in a direction that lets you enjoy music naturally, rather than making the sound flashy.
If you want “a little more sound thickness,” “greater resolution but without letting the sound become thin,” or “to enhance the expressive power of your entire system,” please feel free to consult us. We’ll guide you with a sensible approach, including whether to proceed with a cable replacement only—or whether to review adjustments or other parts first.
