Luxman P-100 Centennial Headphone Amplifier

In 1925, inspired by an experimental broadcast from Japan’s NHK, a visionary businessman crafted a prototype radio receiver and shared its technical manual. This breakthrough captured the imagination of audio enthusiasts, igniting excitement and innovation.

From this spark, Lux was born. The company soon ventured into designing and manufacturing radio tuners, amplifiers, and speakers laying the groundwork for what would become modern audio systems. Through relentless innovation and craftsmanship, Lux evolved into the brand now known as LUXMAN.
Now, a century later, we proudly celebrate 100 years of sonic excellence. To honor this milestone and step boldly into the future, LUXMAN has refined its expertise and perfected its technology to create the “CENTENNIAL” models designed to set new benchmarks in performance and sound quality for the next century.

Leading this special lineup is our flagship P-100 CENTENNIAL headphone amplifier, a testament to our legacy and our commitment to the future of high-fidelity audio.

A Symphony of Pure Sound
Immerse yourself in the pinnacle of headphone listening.

Feel the true essence of recorded sound from the hush of silence to the soaring heights of a crescendo. More than sheer power, this headphone amplifier unveils the finest textures, the boundless depth of the soundstage, and the rich emotional resonance that brings music to life.

Fully balanced headphone outputs, four discrete power amplifiers

The P-100 CENTENNIAL is a high-performance headphone amplifier featuring fully balanced architecture, enabled by uniting four independent amplifier blocks, enhanced by our advanced LIFES amplifier feedback engine. These identical amplifier modules have been meticulously designed using discrete components for optimal audio fidelity. Balanced output: Using a BTL (bridge-tied load) configuration, the balanced output combines the positive and negative signal outputs from four independent amplifier blocks. This setup enhances channel separation, positional accuracy, reduces intermodulation distortion and improves power regulation.

Unbalanced output: The unbalanced output employs a parallel drive system, combining two amplifier circuits per channel to double the output current, ensuring ample driving power. When using the balanced output terminal (φ4.4mm or 4-pin XLR), a switch allows for parallel unbalanced operation with independent left and right grounds. For the ultimate headphone listening experience, connection to two P-100 CENTENNIAL units via their 3-pin XLR outputs offers parallel BTL balanced drive. This mode employs all eight available amplifier blocks, doubling the current output per channel, yielding unmatched, exquisite performance.

Abundant output terminals to suit your choice of headphones

The headphone outputs provided by the P-100 CENTENNIAL have been engineered to connect to a wide variety of high-end headphones available across the global market. In addition to a standard (unbalanced) φ6.3mm output terminal, there is a 4-pin XLR terminal and a φ4.4mm terminal, both balanced outputs. In addition, a 3-pin XLR terminal is also provided as a dedicated terminal for the parallel BTL balanced output mode using two P-100 CENTENNIAL units.

Various settings and adjustment functions
eliminate sound quality degradation

By applying LECUA processing, the unit offers three levels (0, -6, -12dB) of sensitivity switching, LR balance adjustment (0.5dB steps, LR 0 to -12dB) and output mute functions that match the impedance and efficiency of the headphones used without degrading the sound quality. In addition, the unit is equipped with a volume limit function (6 levels: OFF, -10, -20, -30, -40, -50dB) that sets an upper limit on the volume and protects the listeners’ ears from excessive sound pressure levels.

Independent, High-Capacity Circuits for Each Channel

The power supply features two custom made, large-capacity OI-type transformers, renowned for their high regulation capability, dedicated exclusively to each channel. Additionally, an independent transformer is provided for peripheral circuitry, such as driving relays and LED indicators. The output stage incorporates four custom 10,000μF filter capacitors, while the driver stage includes four custom 3,300μF filter capacitors, all configured independently for the left and right channels. This configuration adheres to LUXMAN’s traditional, high-capacity, highly stable power supply circuit benchmark.
