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 MC 2205?

The circuit is always designed to be moderately biased against changes in temperature. The power transistor is class AB operation and the bias current is secured by a thermistor.\ \ The output-stage employs a single-ended para-push method and consists of six highly reliable complimentary service power transistors. Since this circuit is a balanced emitter-follower connection, it has good stability and low distortion. Moreover, the unique output-bias circuit realizes class B operation without crossover distortion.\ \ The output signal of the MC2205 passes through an output transformer, which is designed to match the output terminal of any impedance so that the maximum output is obtained for all frequency signals regardless of the output terminal.\ This transformer also protects the speakers in the event of an amplifier failure. When a DC component is mixed into the output, the transformer eliminates the component and prevents damage to the speakers.\ To prevent overloading of the output transistor, the output signal is always monitored by a Macintosh proprietary monitoring circuit. This circuit becomes high impedance when the output level exceeds the rated value, but this has no effect on the output. When the output reaches its maximum value, the monitoring circuit limits the signal supplied to the output transistor to prevent shorting of the output of the amplifier or damage to the output transistor. This monitoring circuit monitors the plus and minus sides of the output signal separately. \- Audiodatabase

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.

Other McIntosh Products We Often Buy

Typically, StereoBuyers purchases mostly used amplifiers, especially the vintage amps and high-end McIntosh models such as the MC202 or MC252, and the C220 preamp, for example. We have also purchased many pre-owned tuners from McIntosh over the recent years, including the MR67 and MR78 models, for example.

StereoBuyers has purchased tens of thousands worth McIntosh brand equipment since 2014, with individual buys ranging from $100 to well over $50,000. If you are moving, ready to upgrade, or have McIntosh equipment you do not or will not be using, why not contact us today to find out if it is worth good money?
