McIntosh MC602 Amplifier 600Wx2  $6999

I believe this is the most powerful stereo amplifier McIntosh ever built.   There is currently a 600W model, the MC601 but those are monobloks and cost $14k.  

Here is your chance to own the most powerful McIntosh single chassis unit. 

It is a monster and weighs more than a small elephant.  


Pride of ownership. That was the first thought that came to mind as I unboxed the first of the three McIntosh Laboratories MC602 power amplifiers. This massive amplifier, at $8,000 is not McIntosh’s most expensive amp, but it is the most powerful in this manufacturer’s long history. The MC602 is a solid-state stereo amplifier rated at 600 watts per channel. This large amplifier weighs 155 pounds and measures 17.75 inches wide, 11 inches high and 19.6 inches deep.

The front panel is dominated by two large, lighted blue meters, which are flanked by sturdy handles. Below the meters is an illuminated McIntosh logo and two knobs. The left knob controls the meters, and can be set to normal operation where the meter displays the current output in watts for that channel. The left knob also has a hold position in which the meter pauses to display peak output and a lights-off position. The right knob is also a three position knob controlling the power, with on, off and remote settings. In the remote setting, the power can be controlled with a compatible preamplifier.

The rear of the amplifier features two-, four- and eight-ohm taps for each channel, and both balanced and single-ended inputs and remote inputs for automatically powering the unit.

The MC602 has a fully balanced design, featuring a double-balanced, push-pull configuration. McIntosh uses their exclusive impedance matching output autotransformers. This powerful amplifier is full of features to ensure that the power is delivered safely, including clipping protection, current protection, thermal protection, DC failure protection and a turn-on delay with a soft start to protect against sudden surges and ensure a long product life.

This particular sample is in perfect working condition and came to us from the original owner.  The glass is absolutely perfect and so area ll the controls and trims.  The paint is near perfect although there is a corner where the paint is a bit shinier than the rest like a rub mark.  Unlike the newer units this model uses the heavy duty front glass which looks amazing.  

All bulbs work and the meters are fast and responsive.  The unit has been tested on our bench and passed with flying colors.  Its amazing how quiet an amplifier with this power rating can be.  

On the back you’ll find the most heavy duty speaker posts we’ve seen along with balanced and single ended inputs and a removable power cord.  Speaking of power you’ll need to be sure you have an outlet capable of delivering 15 amps which means it should not be shared with any other heavy equipment.  

Unit will be shipped in a McIntosh double amplifier box for safe arrival.  Includes unit, manual and power cord. 

These units are rare and don’t come up often so it is priced accordingly. 

Available for pickup in NYC/NJ.
