Great integrated from McIntosh built just before they started including DACs in all their models. This one won't be outdated anytime soon. Has facilities for an optional tuner card in case you'd like to turn it into a receiver.

Some of the best features include balanced CD inputs and jumpers for the pre-power sections, allowing you to turn this into a great preamp one day if you decide to go the separate amplifier route.

The least expensive integrated from McIntosh today would cost you $5,500 and would only deliver 100W. This one is twice as powerful at 200W!

This is a complete set including the manual, remote, power cord and heavy duty official McIntosh double box with a plywood base.

McIntosh MA6600 Integrated Amplifier Owner's Manual

Performance Features:
• Power Output with Patented Autoformer
The MA6600 consists of a 200 watts per channel stereo Power Amplifier with less than 0.005% distortion. The McIntosh designed and manufactured Autoformer allows connection of 2, 4 or 8 ohm Loudspeakers. The Power Amplifier uses Thermal Trak1 Output Transistors for lower distortion and cool operation.

• Electronic Switching and Balanced Connections
The Preamplifier uses Logic Circuits controlling Electromagnetic Switches on all inputs and operating functions for reliable, noiseless, distortion free switching. There is a Balanced Input for connection of source components.

• Power Guard
The patented McIntosh Power Guard circuit prevents amplifier clipping and protects your valuable Loudspeakers.

• Special Power Supply
The large Power Transformer, multiple filter capacitors with 100 Jules of Energy Storage and regulated Power Supply ensures stable noise free operation even though the power line varies.

The SkyFi Testing Process for Integrated 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.
