Vintage Pioneer M-22 // Solid-State Amplifier / Restored WG1003957

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 piece is in top shape electronically, and performed well in our bench tests. If you look very closely, you'll see the front badge has a few nicks, but fade from a listening position. We're sure you'll fall in love with the sound of this amp, just be ready to answer the question, "What is that?"
