Luxman "M-10X" the Power Final of 100°anniversary of its foundation

Luxman is ready to bring out on the market the new flagship model among the stereophonic end amplifiers, the new Luxman "M-10X" stereo power amplifier equipped with the new and exclusive feedback circuit called "LIFES" which was developed in anticipation of the hundredth anniversary of its foundation in October.

As a successor model of the M-900u released in 2013, the heart of the power amplifier circuit was totally renewed. It will be a new flagship model developed with the aim of overturning audio quality.

In the amplification section the famous "ODNF" amplification circuit has been renewed that since 1999 supports the sound quality of the products Luxman.It comes for the first time, applied the brand new circuit called LIFES that gives more body and more vivid sound, a greater control of the speakers improving soundstage and detail. LIFES is the abbreviation of "Luxman Integrated Feedback Engine System, which integrates an amplification feedback circuit consisting of a main amplifier and a distortion detection circuit and plays a central role in amp products that control music signals.

LIFES" new concept amplification feedback engine"

With the improvement with the introduction of the LIFES circuit, the difference amplifier that detects the distortion in order to greatly improve the static characteristics of the amplifier circuit, It managed to reduce the number of parallel elements improving the performance and, significantly changing the operational configuration of the entire amplifier circuit, the distortion during amplification was reduced by about half.

To support the delicate amplification operation that conveys the delicate nuances of the musical signal, the constant voltage circuit of the driver stage and the input conversion amplifier has been renewed combining a new circuit-source of constant high performance current and a Zener diode made by Bishui. Logicly, to ensure the best energy the new Luxma M-10X has been equipped with a high inertia power supply that is resistant to input fluctuations and load fluctuations ensuring the reproduction of all music details.

Moreover, for the purpose of the stable operation of the amplifier circuit, within LIFES per channel are arranged four constant current circuits of the current type to mirror current that use double transistors to control the temperature and the power voltage of the environment in which the product is installed.

Improved also the temperature compensation of the current amplification stage for more stable product operation by combining a transistor and a thermostore to suppress polarization fluctuations.

The nominal power is 150W + 150W (8Ω) and 300W + 300W (4Ω) in stereo. 600W (8Ω) in mono. The maximum power is 1,200W + 1,200W (1Ω) in stereo and 2,400W (2Ω) in mono. , supports operation in pure class A up to 12 W.

Has an output configuration 4x2 combining a 3-stage Darlington push-pull output module with 4 parallel stages and using a copper plate collector bar without extra oxygen for the main line from the power supply to the output stage. The BTL straight circuit configuration is such that the conversion amplifier does not pass through the cold signal when the BTL mode is balanced. Also equipped with a high coupling and low loss EI type superregulation power transformer that uses flat angle copper windings.

For all audio circuits a substrate is used covered with gold coating without resistance of the thickness of 100 μm which eliminates the dielectric effect of the resistor. A high depreciation factor was obtained by a large speaker relay with parallel connection to 4 contacts and a direct connection method with collecting bar at the end of the speaker.

The back of the main unit

There is an unbalanced input and a balanced output. The input terminal is equipped with copper alloy RCA, which has the same conductivity of copper and the hardness comparable to the brass. In addition, it is equipped with a new trigger input/output terminal that allows the interlocking of the power between compatible products and an AC input that has been subjected to non-magnetic treatment by means of gold plating.

Front of the main body

The front panel is centered on a needle analog meter that uses light bulb LED lighting that shines in the listening room, while maintaining the concept of authentic look that inherits the M-900u with a small diameter function switch and analog meter memory The design has been modified in one with greater visibility. Also the mounting position of the indicator has been modified so that the operating indicator (for the L channel) is at the center in BTL mode (monofonic).

The housing itself has a three-dimensional layer structure that expresses a bold "neck" between the top model of the SACD player "D-10X" and the common bonnet, "presence as component and richness of sound. , Delicacy" is designed.

The energy consumption is 530 W. 280W in the absence of signal. The external dimensions and weight are 440 x 488 x 224 mm (width x depth x height), 48,4 kg.
