【C-ONE Power Amplifier｜A Class AB Amplifier that Supports Natural, Refined Music Playback】

This is a power amplifier worth considering for those who want a bit more thickness and power in the sound from their factory audio, or for those who have replaced their speakers but feel they still haven’t fully brought out their original performance.

C-ONE is a Class AB power amplifier that inherits the design philosophy of BRAX power amplifiers. It uses a Class AB circuit, which is considered advantageous for sound quality, and is built with MOS-FETs in an 8-parallel configuration, aiming for power and stability that can drive your speakers firmly.

It’s suited for anyone who wants to take a careful look at how their favorite tracks sound—not only when turning up the volume, but also in the expression of vocals, the attack of instruments, and the overall thickness of the music. Instead of dramatically changing the sound, if you want to let your speakers and the entire system sound calm and well-balanced, and finish it in a direction that’s less fatiguing even during long listening sessions, then—if it were me—I’d put an amplifier like this on the shortlist.

The power supply section uses MOS-FETs in a 6-parallel configuration and employs a power-supply circuit that combines a large toroidal transformer with high-capacity capacitors. In addition, it’s designed so that the amplifier is less likely to turn off even if the supply voltage drops for a short time, with consideration for avoiding audio dropouts that can occur in idle-stop vehicles.

However, a power amplifier is not a product that produces the exact same sound just by installing it. Depending on the vehicle model, the factory system, and the combination with your speakers, the approach to things like input methods, installation methods, and gain adjustment will change. It’s important to install while keeping an eye on the overall balance of the system, including wire handling, securing the amplifier, and adjustments after installation.

At LOGON, we don’t judge based on the performance of the C-ONE alone. We guide you by checking what you’re dissatisfied with in your current sound, what kind of music you listen to most often, and how well the speakers and factory audio match. Let’s also sort out together what will change by adding an amplifier, and where spending money is more likely to lead to satisfaction.
