The stunning control and authoritative power of the Michi M8 Monoblock Amplifier is the result of a perfect balance of science meets art delivering 1,080 watts of Class AB power into 8 ohms and an astounding 1,800 watts to the most demanding 4 ohm loudspeakers. The M8 is powered by a pair of custom engineered, low noise, in-house manufactured toroidal transformers supported by 4 British patented slit foil, high efficiency, low ESR bulk storage capacitors for impactful bass with exceptional control under extreme loading conditions.
To achieve accuracy and its unsurpassed performance, the M8 is equipped with an array of 32 high current output transistors thus reducing the load on individual components and maintaining the crucial energy, rhythm and timing throughout the amplification stages. Musical expression and detailed refinement were further accomplished through acoustic tuning of all critical components and a balanced circuit design.
A high resolution display adorns the front panel supporting a peak power meter or spectrum analyzer. With XLR and RCA inputs, 2 sets of custom Michi speaker binding posts, remote control and fully featured RS232 and Ethernet connections the M8 provides ultimate installation flexibility. Power amplification at its best in the most elegant of industrial designs.

. . . εδώ η ιστορία , το θρυλικό τους phono . . .
The PCB of the RHQ-10 is made of high-grade fiberglass with 0,1% and 0,01% tolerance metal film Vishay resistors in the signal paths, eq and NFB loop.
The first and head-amp stage is a triple parallel differential fully complementary push-pull ; the second stage is a passive pole low-pass filter ; the third is a low frequency boost and gain stage.
The output stage is a single-ended fully complementary push-pull circuit in Class A. Discrete components throughout.
One input is available, with two outputs : Fixed 1 is for connection to a passive controller or preamplifier which bypasses the volume control ; Variable is for going directly into a power amplifier ; Fixed 2 is for connection to a passive controller or preamplifier when using a moving coil cartridge of extremely low output.
The MM / MC gain & impedance selection however remains mysterious and rests on "an ingenious method to minimize any adverse effect upon sound quality often cause by mechanical switching" - anyone ?
