Accuphase P-4600 Power Amplifier

Envelops you in pure music listening

The Accuphase P-4600 Power Amplifier is a high-end stereo power amplifier designed for the most discerning listener. It boasts a robust build quality, cutting-edge technology, and exceptional sonic performance, and is a true centerpiece for any high-fidelity sound system.

The P-4600 delivers a robust 150 watts per channel into 8 ohms, doubling to 300 watts into 4 ohms. This ample power ensures it can drive demanding speakers with ease, faithfully reproducing even the most dynamic musical passages.

Groundbreaking technology

The Accuphase P4600 power amplifier utilises a sophisticated Class AB design that combines the best of both Class A and Class B amplification for a perfect balance of power, efficiency, and sound quality.

Accuphase employs top-of-the-line components throughout the P-4600, including custom-wound transformers, high-grade capacitors, and meticulously selected transistors. This attention to detail results in exceptional audio clarity and accuracy.

Power amplification section with linear output characteristics

The power amplification stage of the P-4500 features bipolar power transistors mounted directly to large heat sinks for highly efficient thermal dissipation. The devices are configured as a triple Darlington 4-parallel complementary push-pull circuit that is capable of doubling the rated output when the impedance is halved. In other words, it achieves a fully linear power progression of 90 watts into 8 ohms, 180 watts into 4 ohms, and 360 watts into 2 ohms. It can even supply loads as low as 1 ohm with 500 watts of power (music signals). The impressive damping factor of 700 means that the amplifier has ample leeway to drive any kind of loudspeaker.
