- Liner Notes
McIntosh co-founder Gordon Gow knew a growing market when he saw one but had trouble convincing his partner Frank McIntosh to make the move. As the head of sales, Gow pushed for McIntosh to come out with a receiver in the ’60s but “Mr. McIntosh said no,” relates Ken Zelin, historian and director of U.S. sales training at McIntosh. “Receivers involved some degree of compromise, so year after year, he overruled Gordon.”
Finally, the owners came up with a solution they both could live with. “They would build a receiver in the McIntosh factory but not call it a McIntosh,” Zelin reveals. “They formed a division called MAC Audio Company to market the receiver. It was built in the McIntosh Lab factory and sold through McIntosh Lab dealers but if you look at the receiver and its manual, both say MAC instead of McIntosh.”
