McIntosh is one of the most dependable brand names when it comes to high-end audio systems. For years the brand has been recognized by audiophiles throughout the world as equipment that delivers clear and consistent quality in music. McIntosh is probably best known for its amplifiers and preamps, but the company produces many other components and parts for stereo and home theatre.

What else to know about the McIntosh MA 6100?

The MA 6100 is a 70-watt Vintage Pre/amp -Amplifier sold during the seventies. It replaced the 45-watt MA 5100 ($449.00) from 1966 and was itself replaced by the 75-watt MA 6200 ($1,899.00) which went until 1991. The 6200 was pretty much the same except it had an equalizer and anti-clipping added in response to the then new digital sources. I lived with the MA 6100 for over fifteen years, then had a MA 6200 for over ten years. I did not use the equalizer, and I can do not need Power Guard to keep from blowing out my speakers. Now I am back with the MA 6100. Both have Headphone amps and no meters.\ \ The 6100 has dual concentric tone controls. They decrease turned to the left, flat straight up, boosted turned to the right. They function, but really they are just decoration and will never wear out from turning. The balance control reduces the signal to the opposite side it is turned, to give equal sound pressure to the listeners ears. The on/off switch, volume control has an audio taper curve. It is a modified logarithmic curve starting with a dead zone. When you turn the knob, you can hear the volume change.

Brief History of McIntosh

Long mapped-to Binghamton New York – the current headquarters and manufacturing center for McIntosh Labs – not many people know the brand was originally launched outside of the Nation’s Capital in Silver Spring Maryland, in 1949. In 1956, the brand built their original facility in New York, according to the official brand website.
