Power inside
The M-10X is specified as delivering continuous power up to 150Wpc into 8 ohms and 300Wpc into 4 ohms (both equivalent to 21.76dBW), the first 12W in class-A. As a bridged monoblock, the Luxman will deliver 600W into 8 ohms (27.8dBW). The maximum instantaneous power is said to be 1.2kWpc into 1 ohm in stereo mode, 2.4kW into 2 ohms in bridged-mono mode.

Each channel's output stage uses eight complementary pairs of Darlington-connected transistors. The power supply features low-loss Kyocera Schottky rectifier diodes, a low-loss EI-type power transformer with flat copper windings, and 80,000µF of filter capacitance. Current is delivered to each channel's output transistors with a thick copper bus bar; another bus bar connects the devices' push-pull output to the speaker binding posts via a high-quality relay. This relay has four switch elements connected in parallel to reduce contact resistance. The power supply rails for the driver stage use high-performance regulator chips and selected Zener diodes, the latter manufactured by Vishay in the United States. The 0.1mm-thick traces on the printed circuit boards are gold-plated.
