Here is a fine McIntosh MC-2100 Stereo Power Amplifier. If you are looking for a good one, look no further. This one has been meticulously cared for it's entire life. It comes with the original warranty, all records of service, original service manual, and original box and packing materials. It has been kept up to spec and has three performance certification badges on the back from visits to McIntosh Clinics. At one clinic it was rated at 148 wpc, pretty incredible for a 105 wpc amplifier. These amplifiers are tireless powerhouses.
The MC-2100 uses McIntosh designed trifilar autoformers which make them the only amplifiers to deliver FULL POWER AT ALL SPEAKER IMPEDANCES. You will not be power penalized for your choice of loudspeakers when using the MC 2100. Another advantage of the autoformers is the 25 volt output for a constant voltage distribution system. This allows several sets of speakers to be operated independently throughout your home.
The sound of this amplifier is stunning. Wonderful, delicate, detailed highs, and thunderous controlled bass. It is guaranteed to be in perfect operating order. Cosmetically it is in excellent condition. All lettering is perfect, no rust, the chrome is nice with normal swirling cleaning marks. Not perfect, but probably as nice an example of this fine amplifier as I have seen offered in quite some time. Certainly the best documented, which allows one to go back in time with this piece. Pretty neat.
