Accuphase P-4600 Power Amplifier Class AB

The P-4600 follows the technology of the P-7500 and incorporates the latest technology, and the high-power design unique to Accuphase Class AB power amplifiers has achieved a significant increase in maximum output, making it a high-performance, high-output power amplifier. The "low noise" achieved by the polished, ideal balanced circuit (instrumentation amplifier method) and the "high output" achieved by the powerful power stage supported by an unshakable power supply unit provide ample driving force. The impressive aluminum die-cast heat sink is integrated with the aluminum front panel and chassis to achieve a robust structure. The top plate uses a luxurious hairline-finished aluminum panel, and combined with the traditional champagne gold front panel, it exudes a style that goes beyond its class.
