McIntosh MC206 - 6 Channel Audiophile Power Amplifier - 120W x 6!


There are so many uses of this exemplary amplifier that come to mind. Besides your standard home theater configuration, this could be used to bi-amp or tri-amp a set of speakers. You could also use it as a formidable multi-room amplifier powering up to three separate rooms. 

Best of all, it will likely be the most reliable amplifier you'll ever own thanks to the legendary McIntosh build quality and parts selection.

We took care of its only weak point - the internal incandescent bulbs that tend to last about 10 years. We also cleaned all the controls and put this through its paces via our testing standards, noted below.

The unit is super minty with no signs of use or abuse. The glass is intact and the casework Is nearly perfect. Any imperfections you see on the glass in our photos are from glare. On the bench it produced every watt it is supposed to and more, extending power well beyond the rated 120W.

Technical Notes:
All channels test to 150W+ under an 8 ohm load before clipping. Well over 200W into 4 ohm. McIntosh Power Guard working normally. Listening test passed on all channels. Meter function perfect.

More from McIntosh:

Now you can take advantage of traditional McIntosh standards of excellence in the MC206 Power Amplifier. Six 200 watt high current output channels will drive any high quality loudspeaker system to its ultimate performance. The MC206 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is 􏰁The Sound of the Music Itself.􏰂

Performance Features:
• Power Output
The MC206 consists of six Power Amplifier Channels,
each capable of 200 watts into 4 ohm or 120 watts into 8 ohm loudspeakers with less than 0.005% distortion.

• High Current Output
A peak output current of 25 amperes per channel ensures
that the MC206 will successfully drive high quality loud- speakers such as McIntosh for a truly exciting sound expe- rience.

• Power Guard and Sentry Monitor
The MC206􏰀s Patented McIntosh Power Guard Circuits
prevent each of the amplifier channels from being overdriven into clipping, with its harsh distorted sound that can also damage your valuable loudspeakers. The Sentry Monitor Power Output Protection Circuits ensure the MC206 will have a long and trouble free operating life.

• Illuminated Power Meters
Three Front Panel Illuminated Power Output Meters can be
selected to precisely indicate the power output of each of the six channels.

The SkyFi Testing Process for Solid State Amplifiers:

We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage.

We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier then remains powered on to "burn in" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will be also be tested.

Final testing involves pushing actual music thorough the amplifier. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we're very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.
