{"product_id":"accuphase-p-7500-power-amplifier","title":"Accuphase P-7500 Power Amplifier","description":"\u003cp\u003eThe Accuphase P-7500 Power Amplifier is a high-performance audio component designed to deliver exceptional power, precision, and sonic performance. With its dual mono configuration, AAVA volume control, and high-grade components, the P-7500 ensures exceptional sound quality and reliability. This amplifier is perfect for audiophiles seeking to elevate their listening experience to new heights.\u003c\/p\u003e\u003ch3\u003eLow-noise balanced signal paths\u003c\/h3\u003e\u003cp\u003eThe balanced input stage circuitry features instrumentation amplifier topology such as used in high-precision measuring equipment. To achieve ultra low noise, the input stage gain is set to a high value, which in turn allows using a high power supply voltage so that distortion at large amplitudes is eliminated. Signal purity is further elevated by the use of ultimate-quality fully discrete components.\u003c\/p\u003e\u003ch3\u003eFurther refined MCS+ topology for even lower noise\u003c\/h3\u003e\u003cp\u003eAccuphase's original MCS (Multiple Circuit Summing) principle uses a number of identical circuits connected in parallel to achieve superior performance characteristics. MCS+ is a further refined version of this approach, which extends the parallel operation approach to the class-A drive stage of the current\/voltage converter, thereby further lowering the noise floor.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eContinuous Average Output Power:\u003c\/strong\u003e Stereo operation - 800 watts per channel into 1 ohm, 500 watts per channel into 2 ohms, 250 watts per channel into 4 ohms, 125 watts per channel into 8 ohms.
