The Luxman B-10II is a mono power amplifier that was manufactured from 1995 to 1999 in Japan. With a front panel crafted from aluminum in a gold finish and a wooden housing cover in piano lacquer, it presents an elegant design. The amplifier has a power consumption of 560 W and dimensions of 467 x 233 x 482 mm, weighing 43.5 kg. It was originally priced at approximately 650,000 yen in Japan, equivalent to around 16,998 DM per unit. The B-10II features two inputs with an input sensitivity of 1V for 500W output at 8 Ohms, and an input impedance of 50 kOhm for asymmetrical connection and 100 kOhm for balanced connection, along with a single speaker output.
In terms of technical specifications, it provides continuous power of 500W at 8 Ohms and 1000W at 4 Ohms, ensuring significant power output for various speaker loads. The amplifier has a low total harmonic distortion of 0.04% across the frequency range of 20Hz to 20kHz, with a frequency response of 20Hz to 20kHz (+1 / -0.5dB) and 10Hz to 100kHz (+0 / -1dB). A signal-to-noise ratio of 115dB enhances audio clarity.
A unique feature of the B-10II is its use of a comprehensive CSSC (Complementary Symmetry Super Class A) configuration, utilizing eight 200W class multi-emitter transistors for both the positive and negative signals, totaling 16 transistors. This design minimizes distortions and preserves the integrity of sound quality. The amplifier is also equipped with a large VU meter, input attenuators, and a line phase sensor to ensure proper AC power polarity.
Carefully designed for resilience against external noise, it incorporates a 5-point grounding system and high-rigidity chassis to mitigate vibrations. The power supply uses an 800 VA EI transformer and a 22,000μF custom-made capacitor to maintain stability during operation. Multiple custom components, including a large power transformer, and advanced filtering measures, further enhance sonic performance. This amplifier combines aesthetic appeal with sophisticated sound engineering, making it a significant unit in Luxman's lineup.
