New Amplification Feedback Engine
Equipped with LIFES™ Ver.1.1
LIFES™ (Luxman Integrated Feedback Engine System) with Quadruple-Parallel, Quadruple Output Stage Configuration is an amplification engine designed to breathe life into every musical signal. Developed with LUXMAN’s centennial vision in mind, LIFES inherits the fundamental concept of our acclaimed ODNF™ (Only Distortion Negative Feedback) architecture while being completely redesigned from the ground up. Every aspect of the circuit has been renewed to achieve a simpler, more compact design utilizing carefully selected, high-performance components that ensure long-term supply stability. LIFES feeds back only distorted audio components detected as the difference between the input and output signals by a dedicated differential error amplifier. This unique approach combines the natural openness and vitality of a non-feedback amplifier with the outstanding linearity and stability of negative feedback amplification, achieving an exceptional balance between musicality and technical performance. Five years after its debut in the M-10X in 2021, LIFES has continued to evolve through implementation across numerous LUXMAN components. Now, Version 1.1 further improves performance by paralleling the input stage of the differential error amplifier, resulting in even lower distortion and higher precision. The B-100 CENTENNIAL features the latest LIFES Ver.1.1 in LUXMAN’s most ambitious output stage to date. Four independent output modules, each employing a three-stage Darlington cascade, are quadruple paralleled in a push-pull configuration, forming a 4 × 4 output architecture that represents the highest-capacity implementation of LIFES ever realized. With meticulously optimized bias current, the amplifier operates in pure Class A up to 25 watts (8 Ω) while delivering 125 watts into 8 Ω and an instantaneous peak output of 1,000 watts into 1 Ω. The result is extraordinary power linearity and unrivaled drivability, allowing the B-100 CENTENNIAL to reproduce music with remarkable naturalness, effortless dynamics, and an exceptionally open, vibrant sound.

Highly-regulated Power Supply
Large EI-Core Power Transformer and High-Capacity Filter Capacitors
To faithfully reproduce not only every nuance of the musical signal but also the emotion behind it, an amplifier must respond instantaneously to constantly changing demands for power. LUXMAN’s answer is the Highly-regulated Power Supply. By combining a large, highly regulated power transformer with exceptional voltage stability and high-capacity filter capacitors capable of delivering massive instantaneous current, the amplifier maintains a vast reservoir of stored energy. This “energy reserve” enables it to supply power effortlessly and without hesitation, even during the most demanding musical transients. The power supply that supports the B-100 CENTENNIAL’s formidable output of 125 W into 8 Ω and an instantaneous peak output of 1,000 W into 1 Ω is the most powerful ever incorporated into a LUXMAN amplifier. At its heart is a 1,250 VA Super Regulated EI-core power transformer, wound with rectangular copper wire to achieve exceptionally high magnetic coupling and low power loss. Working in tandem are sixteen custom-developed 10,000 μF filter capacitors, first introduced in 2021 and now employed across numerous LUXMAN products, providing a total capacitance of an extraordinary 160,000 μF. The transformer is mounted on vibration-damping rubber within a dedicated, shielded compartment on the left side of the chassis, isolating it from both mechanical vibration and electromagnetic interference. The sixteen filter capacitors are arranged in two vertically stacked banks of eight, with each bank linked through equidistant, closely positioned connection points. This optimized layout minimizes impedance while ensuring efficient current delivery throughout the amplifier, contributing to its exceptional stability, dynamic performance, and effortless musical expression
