Following the L-100 Centennial Class A integrated amplifier, the D-100 Centennial CD player and the P-100 Centennial headphone amplifier, LUXMAN continues to celebrate its 100th anniversary with the B-100 CENTENNIAL mono power amplifier.
The new flagship of the Japanese brand’s amplifiers, it is the first monoblock model of its kind since the B-1000f, launched in 2005 to mark the 80th anniversary. At its heart beats the latest version of the LIFES 1.1 amplification circuit. Derived from the LIFES circuit first introduced in the M-10X in 2021, this latest iteration has been further optimized to reduce distortion even further and improve overall performance.
The B-100 Centennial adopts a new ‘4×4’ output configuration, consisting of four triple-stage Darlington push-pull modules in a quad-parallel arrangement for each channel. This configuration delivers 25 W in pure Class A at 8 Ω and 125 W in Class AB. At 4 Ω, the power doubles to 250 W and quadruples at 2 Ω to 500 W. Capable of reaching up to 1,000 W peak power at 1 Ω, it aims for total linearity and absolute control over the speakers, reinforced by a damping factor exceeding 1,000.
The main reason for the doubling of power output each time the impedance is halved is the power supply, which relies on a massive, custom-built, high-efficiency 1,250 VA EI-type transformer, featuring flat copper windings to reduce losses and improve coupling. This is combined with 16 filter capacitors of 10,000 μF each (totaling 160,000 μF), which provide a considerable energy reserve. The ‘peel-coat’ circuits are gold-plated without varnish and combined with specific inductors and numerous relays.
The exterior design features a solid, high-quality 5 mm-thick chassis with machined ventilation slots. The thick front panel with a slanted chamfer is reminiscent of the recent D-100 and P-100 Centennial models and, of course, the M-10X stereo amplifier, but features a single warm-lit analogue VU meter at its center.
Sold in pairs at a price yet to be announced in Europe, the B-100 Centennial mono amplifier represents the new pinnacle of LUXMAN’s current technology and expertise and paves the way for future generations from the century-old Japanese manufacturer.
It is scheduled for release in summer 2026.
