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 MAC 4100?The phono amplifier in the MAC4100 uses a new high technology integrated circuit operational amplifier. Its differential input stage has been optimized for low noise and low distortion performance. Electronic input selector switching uses field effect analogue switches. The mechanical input selector simply switches small amounts of DC which turn the FET analogue switches off or on. This design eliminates degradation of frequency response and also eliminates noise pickup from long signal paths necessary with conventional mechanical switching. It means, as well, that switch clicks and pops have been eliminated. The equalizer amplifier is constructed with ion implanted junction field effect operational amplifiers. These new devices amplify signals with a 6 dB better signal to noise ratio than their bipolar counterparts. Amplifiers are capable of delivering large quantities of power when they are driven to clipping. Clipping is caused when the amplifier is asked to produce more power output than it can deliver with low distortion. The MAC4100 has a built-in waveform comparator that compares the wave shape of the input signal with the output signal. If the disparity between the two signals exceeds 0.5% a front panel signal illuminates in red at the top of the power output indicators, with any further increase in distortion the Power Guard circuit will operate.
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?
