Send

The Accuphase P-4200 is a high-end audio power amplifier from the Japanese manufacturer Accuphase. It is part of their Equilibrium Condition Tuning (ECT) series, which is known for its focus on achieving natural, uncolored sound reproduction.The P-4200 is designed to deliver 420 watts per channel into 8 ohms, or 840 watts into 4 ohms, with a very low total harmonic distortion (THD) of less than 0.05% at full power. It uses a proprietary class-G circuitry, which allows the amplifier to operate in class AB for most of its output range and switch to class A for the critical mid-range frequencies, resulting in improved mid-range clarity and overall tonal balance.The amplifier features a balanced input stage, high-quality capacitors and resistors, and custom-made output transistors, all carefully matched and selected for optimal performance. It is also equipped with Accuphase's Phoenix Gold connectors and a heavy-duty aluminum front panel for durability and reduced vibration.Overall, the Accuphase P-4200 is a high-end audio amplifier designed for audiophiles who demand the very best in sound quality, engineering, and reliability. Its focus on ECT and class-G circuitry, coupled with the use of premium components, makes it a top choice for discerning listeners who seek a truly immersive and dynamic listening experience.
