Luxman M-05

 Over the years, Luxman's strength in engineering excellence has always been most evident in amplifier design.

The M-05 (and M-02) represent the latest in electronic technology from Luxman.

These power amplifiers contain the most current circuit designs, including Duo-Beta with single-stage amplification and L.E.D. bias circuitry.

And as the models from which allLuxman amplifier sections are designed, the M-05 and M-02 utilize discrete output transistors and maintain high dynamic power even into low impedance loads.

The top-of-the-line M-05 is a pure class "A" configuration and sonically ranks with the finest amplifiers in the world.

 Power  Supply and "Single-Stage" Amp is now reinforced by "LED" Bias Current

The 1st stage we ventured to use high Gm, low-noise FET for head-amp at the 1st stage. In this way, we succeeded in removal of the 2nd stage to form an ideal amp having only one stage for voltage amplification.

Ample Power Supply

A slim but effective power transformer with outstanding regulation is newly designed for this high quality separates, which ensure longlasting, stabilized performance in combination with the select capacitors specially developed for audio use. Especially, the power transformer employed this time offers far better efficiency than those with the conventional EI core, which makes it possible to reproduce soild bass sound

Unconditional Stability

"Single-Stage" amp thus created totally banishes various hums inclusive of power supply noises hitherto amplifies by the 2nd stage, and at the same time ensures high stability with the highest slew rate.

LED Bias Current System

Unprecedented speedy attack and decay are given in the actual auditory feelings thanks to our unique bias current circuit employing LED's in lieu of normal diodes. In fact, the LED provides very sharp rise and decay in the statics when compared with silicon diode, and therefore ensures stable bias power supply. In addition, it is possible to cope with even an unexpected, sudden fluctuation due to its inherent high-speed response.

Furthermore, the inter-terminal voltage per LED is higher than that of diode in general, and to share the same voltage the smaller number of LED's will do in comparison with that of diode. Thus, the esponse speed as well as the decay and rise characteristics show multiple effect, providing conspicuous improvement in the auditory feelings. Unexperienced pure sound is now unveiled.
