Accuphase P-6100 700W/1Ω Stereo Power Amplifier :
The P-6100 is a stereo version of class AB monophonic power amplifier M-6000, inheriting its outstanding design technology. It features instrumentation amplifier topology and a further refined MCS+ circuit, as well as the current feedback principle to minimize noise. In the output stage, high-power MOS-FET device srenowned for their great sound and utter reliability are used. MOS-FETs have excellent frequency response and high input impedance which reduces the load on the preceding driver stage. They also have perfect thermal stability. In each channel ofthe P-6100, 16 of these devices are arranged in an 8-parallel push-pull configuration. The massive heat sinks on both sides of the chassis achieve efficient dissipation of thermal energy and ensure stable operation. This allows the amplifier to deliver an amazing 700 watts ofpower per channel into an ultra-low impedance load of 1 ohm (music signals). The linear power progression with a rating of 440 watts into 2 ohms,220 watts into 4 ohms, and 110 watts into 8 ohms means that the amplifier can competently handle even speakers with very low impedance or withd ifficult impedance curves.
