The McIntosh MC75 is one of the most lauded amplifiers of all time. So good, in fact, that McIntosh resurrected this design, not once but twice. This pair rolled off the line in 1964, and despite the typical pitting and patina, these are some of the most sonically perfect MC75s we've had the pleasure to audition. Fully serviced, this pair includes a very nicely matched tubeset with Gold Lion output tubes. A rare chance to own a pair of audiophile history.
