PIONEER M-22 (1978) - Series Twenty Class-A

 

The culmination of PIONEER's creative design can be heard with the esoteric Series Twenty Class-A components which achieve the exceptional warmth and presence of valve-type amplifiers without the drawbacks of the old designs. The Series Twenty was launched in 1978 to prove just how "high" fidelity could really reach if the cost factor is eliminated. The PIONEER M-22 is operating strictly in the Class-A mode. Admittedly low on efficiency (watts of output per power input) but unbeatably high on performance. The M-22 obtained the highes compliment when the British journal Practical Hi-Fi said the amplifier "can be regarded as the classic straight wire with gain" Technical data: 30 W/ch min. RMS at 8 ohms, from 10 to 30000 Hz Dimensions (WxHxD) 420x153x370 mm, Weight: 22 kg. Partnering components are the U-24 Stereo Programme Source Selector, C-21 Stereo Preamplifier, D-23 Multi-Amp Electronic Crossover Network.

Technics SB-M10000 (1995) - The Final Word in Sound Perfection

 

The Technics SB-M10000 introduced in 1995 is a 4-Way 12-Speaker limited series loudspeaker system. The SB-M10000 used Dual Dynamic Drives (D.D.D.) that achieved flat response down to super-low frequencies. By developing a Kelton speaker system that alone is capable of the advantages of both sealed speakers and bass-reflex speakers, the SB-M10000 achieved ample frequency response reaching down to deep bass. The speaker was capable of easily reproducing deep bass with a sense of natural and magnificent scale as if floating. The speaker included four passive radiators with 27-cm cones for the low frequencies and four 22-cm cone woofers for driving. Unique push-pull edges reduced distortion by equalizing the amount of air displacement back and forth when amplitude occurs. The speaker included two 18-cm mid-low units using composite mica diaphragms for the lower midrange frequencies, a 6-cm pure-mica oval dome diaphragm unit for the upper midrange frequencies, and a 2.5-cm super graphite dome tweeter for the high frequencies. Given a multi-layer glossy veneer finish limiting diffraction reflection, the cabinet produced a tallboy form increasing the sound imaging in the space. The original sale price was 90.000 DM for a pair. According to some (yet unverified) sources there were only 8 pairs made. Technical data: Frequency response: 20Hz to 100kHz | Impedance: 4ohm | Dimensions: 486*1575*575 mm | Weight: 160kg (Source: Technics)
