A power cable that carefully supports the music’s expression from your feet up.
【Grandio AC-1 (3.0m) | In-Car Interconnect Cable】
You want to increase the amount of sonic information and clearly hear even the subtle nuances in vocals and instruments. This is ZONOTONE’s interconnect cable made for people like you.
Grandio AC-1 features a hybrid structure that combines five materials centered on ultra-high-purity 7N-class Cu: HiFC, high-purity oxygen-free copper PCUHD wire, tinned-plated OFC, and high-purity oxygen-free copper.
While preserving power and liveliness, it expresses the sonic outline and fine details carefully. From breathing in the vocals to the instrument’s attack and even the depth of the soundstage, this cable is designed to bring about changes that can create new discoveries in your favorite songs.
That said, interconnect cables don’t always deliver the same effect simply by being replaced. The appropriate cable depends on the combination with your head unit, DSP, and amplifier, as well as the overall balance of your current system.
At LOGON, we confirm your vehicle model, your current system, and your sound preferences, and then think together about where changes are likely to raise your satisfaction. If it were me, I wouldn’t decide on the cable first—I’d listen to your current sound and then choose where to make the swap. That way, it’s easier to get closer to a finish that truly justifies the cost.
