Accuphase M-6200 Monophonic 1200 Watt 1 Ohm Power Amplifier

The M-6200 approaches the concept of the power amplifier from a new vantage point, achieving an unprecedented level of performance that redefines what a monophonic power amplifier can be. Its discrete ultra-low-noise instrumentation amplifier construction allows fully balanced signal transmission, augmented by the MCS+ circuit and current feedback topology, resulting an amazing S/N ratio of 127 dB at maximum gain and 133 dB at the -12 dB gain setting. Two identical power amplifier units driven in parallel keep output impedance at a minimum, making the amplifier capable of delivering constant current down to extremely low impedance loads. A hefty power supply and high-power transistors arranged in a 16-parallel push-pull configuration deliver 1,200 watts (music signals) into an ultra-low 1-ohm load. The output stage with further powered impedance is rated for a damping factor of 1,000. Its bold and massive appearance notwithstanding, the M-6200 is a monophonic amplifier that not only delivers abundant power and dynamic performance but that expresses even the most delicate and minute musical details with captivating realism
