The Yamaha MX-2 is a resounding good stereo amp. It is not your usual run of the mill stereo amp but a pretty “high tech” unit with some interesting engineering behind it. Like its own Hyperbolic Conversion Amplification (HCA) which is suppose to be better than Class A but with less heat generated and less distortion. It also has an Advanced Power Supply (APS) which provided a very steady and constant voltage to its circuitry. All these play into a pretty neutral and transparent sound with abundant power reserve to drive just about any speakers. The amp can dip down to 2 ohms when required and at that level, it puts out 230W per channel. In 8 and 4 ohms, it will put out 150W and 190W respectively. Volume level controls on the rear allows for very fine tuning and balance between the output from your preamp and the amp itself.
This unit was recently serviced with not up to spec parts replaced and biased back to original factory spec. So it will be good to go for many more years to come. Cosmetically, the unit looks very good. Minor scuff marks here and there but nothing major. Amp will be securely packed for safe shipping. See our other listing for the matching Yamaha CX-630 preamp that collectively, will be one of the best sounding under $1,000 pre/power combo!
