At US$12, this is absurdly cheap versus the normal used market: the MQ104 typically trades around US$150–US$450 depending on condition and venue, with a factory list of US$500 back in the day. If the unit is genuinely complete and functional, this is a bargain-level buy by any sane benchmark.
What makes it worthwhile is that the MQ104 is a classic McIntosh environmental equalizer, valued for helping tune bass to the room and speakers without turning the system into a science project. The upside is obvious if it’s intact: these are collectible, useful, and usually not expensive to ship. At this price, the main thing to verify is that it’s the actual module and not a parts-only shell—if it powers up and the controls aren’t noisy, you’ve got a keeper.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
McIntosh Laboratory, founded in 1949 in the United States by Frank H. McIntosh and Gordon Gow, embodies a storied heritage of American audio innovation. Originally based in Silver Spring, Maryland, before relocating to Binghamton, New York, where products are still handcrafted today, the brand emerged from a commitment to superior sound reproduction. From powering President Lyndon Johnson's inauguration to the Grateful Dead's Wall of Sound at Woodstock, McIntosh has shaped pivotal moments in music history and pop culture, earning its place as a cultural icon.
The company specializes in a comprehensive lineup of high-fidelity components, including renowned amplifiers—particularly its revered tube models for their warm, enveloping sound—along with solid-state power amps, stereo tuners, loudspeakers, turntables, music streamers, processors, and digital-to-analog converters. This breadth supports both two-channel stereo systems and multi-channel home theaters, delivering immersive experiences in music and film. Iconic blue watt meters on their gear have become globally recognized symbols of precision and power.
Positioned firmly in the high-end market, McIntosh commands respect among discerning audiophiles for its uncompromising quality, luxurious build, and timeless design.
