【PA-1502 M's-Tune｜A High-End Power Amplifier That Brings Out Clarity and Power】

When listening to music, I want to see more of the subtle nuances in the vocals. I want to refine the definition of the bass. And I want it to sound great even when I turn the volume up—without the sound breaking up.

For those who feel this way, PA-1502 M's-Tune is a model that revisits and refines each section based on the PA-SERIES amplifiers.

It’s not just a matter of swapping out the amplifier. We also work on the power supply section, the preamp section, and the power-supply capacitors in the output stage, to build a solid sonic foundation for the entire amplifier.

Carefully Improve Sound Clarity and Bass Response in Balance

By strengthening the DC/DC converter, we establish a more stable power supply. In addition, the coupling capacitors and devices in the preamp section, as well as the power-supply capacitors within the output-stage AB-class push-pull circuit, have also been upgraded.

As a result, the target sound changes are finished in the following directions:

• Vocal and instrument contours become easier to hear
• Increased transparency in the mid and high frequencies
• Easier to perceive fine details in the sound
• Better bass rise and a tighter, more controlled low end
• Even at higher volume, the sound tends to come together as a whole
• Reduced distortion and noise, enhancing expression in quiet passages

Rather than simply making the bass louder, this is an amplifier type that improves the overall “view” of the music while giving the low end both force and a sense of speed. Even with the songs you always listen to, you may notice sounds and lingering reverb tails you never noticed before.

It’s Important Not Only What You Use, But How You Combine It

The impression you get from a power amplifier changes depending on the speakers, DSP, power environment, and the in-car acoustic characteristics.

Therefore, choosing the PA-1502 M's-Tune does not mean you’ll get the exact same sound in every car. It’s important to sort out where the sound challenges are in your current system—whether they should be addressed by changing the amplifier, or whether you should review other parts first.

If it were me, I wouldn’t decide based only on the amplifier’s standalone performance. I would first confirm your current system as a whole and how you typically listen, and then think through the combination. I also want to bring out the strengths of the PA-1502 M's-Tune, including adjusting gain after installation and balancing the sound.

At LOGON, we make proposals while confirming your vehicle model, current audio setup, the music you often listen to, and the direction of sound you want to achieve. If you’d like to enjoy your music one step deeper, or you want to review your entire system when changing amplifiers, please start by telling us about your current configuration.

Please note that the M's-Tune model is finished by hand one unit at a time and carefully aged, so its delivery schedule differs from the standard model. If you already use a PA-1502, you may be able to change to the M's-Tune specifications for the difference in cost—so please consult us together with the current condition of your amplifier.

Let’s build a system that you can use for a long time, comfortably, while checking the sound changes together.
