Arguably the pinnacle of the MAC receiver line, the 1900 supports two turntable inputs, and features a fully solid-state design. The MAC 1900 is considered by many to be the first 'high-end' receiver of the modern equipment era, and the collector's market seems to agree. This is as fine a specimen as you're likely to find, and it won't last long.

- 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.”
