Vintage Pioneer "Series 20" M-22 // Solid-State Amplifier / Restored

SOLD , now part of a Private Collection

One of the most sought-after vintage pieces, period, the Pioneer M-22 was in a class all its own. Introduced in 1976, the M-22 was the crown jewel of Pioneer's legendary "Series 20" lineup. This was at the height of the 'Wattage Wars," yet Pioneer confidently presented this amp to serious listeners who cared about other specs - clarity. At full power, this compelling Class A design delivers 10-30,000Hz response with less than 0.01% distortion. This specimen has a few character marks around the base, but passed our bench test with flying colors. Whether you're a collector or a daily driver, this amp is calling you.
