Vintage Pioneer "Series 20" C-21 // Solid-State Preamplifier
SOLD , now part of a Private Collection
The C-21 preamp was one of the original four pieces included in the sought-after Pioneer Series 20, a line of true audiophile components from the late '70s. Take a peek at the specs, but this preamp certainly pushes the envelope. As far as frequency response with minimal distortion, you would be hard-pressed to find a comparable preamp at this price.
