7NAC-Shupreme X (1.5m)
For those who want to cherish every detail of music—this is the one to choose.
【7NAC-Shupreme X (1.5m)｜High-Quality Audio Cable for Car Audio】
For those who want to fine-tune their car audio sound even further, the 7NAC-Shupreme X (1.5m).
Although cables aren’t flashy parts, they are an important element that connects the entire system’s signals. Since replacing speakers, amps, DSPs, and so on has already helped improve the sound, it’s worth being particular about revisiting the signal path as well. This is the cable we recommend considering for exactly that purpose.
Hybrid structure combining five types of conductors
The 7NAC-Shupreme X combines the following five types of conductors using the company’s unique hybrid technology.
- Ultra-high-purity 7N-class Cu
- High-purity copper special alloy
- High-purity oxygen-free copper wire PCUHD
- Silver-coated OFC
- High-purity oxygen-free copper OFC
The manufacturer’s features include not only pure, delicate expressive capability, but also the reproduction of sound density, presence, and a sense of silence.
If you want to hear even the subtle nuances in the sound—or enjoy the textures of vocals and instruments more naturally—this should be a meaningful choice as the finishing touch for your system.
Cable replacement should be considered by looking at the overall balance
Switching to an expensive cable doesn’t mean the sound will change in the same way in every car.
Depending on the combination with your current head unit, DSP, amp, and speakers, the way the effect appears and the recommended order will differ. If I were choosing, I would first confirm what you want to adjust in your current system, and then decide whether to make a change to the cable.
At LOGON, we don’t simply recommend based on the product alone. We guide you after confirming your vehicle model, the equipment you’re using, the music you usually listen to, and the dissatisfaction you currently feel. Including installation methods and cable routing, we work together to create a setup in which you can properly feel the change in sound after installation.
If you’re wondering which parts might be improved with a cable replacement and whether it will suit your current system, please consult us while we check your current configuration.

| Connector Type | RCA plugs with a precision-machined collet-chuck design, nickel-plated body and rhodium-plated pins (an XLR balanced version is also offered) |
| Shielding | Triple shielding: a double inner shield (a thick aluminum-foil wrap plus a high-density braided conductor) plus an independent outer shield of special spring steel with its own ground wire |
