Accuphase Stereo Power Amplifier P-4500

Accuphase P-4500

New Updated Model

Stereo power amplifier with outstanding performance

The quest for the optimal power amplifier has just taken another giant leap forward. The P-4500 features an instrumentation amplifier configuration realized with discrete semiconductors in the signal path, triple Darlington 4-parallel complementary push-pull architecture and many other technology advantages. The result is an impressive S/N ratio of 121 dB, rated output of 500 watts into 1 ohm (music signals), and a damping factor of 700. A newly developed output protection circuit can also detect any short-circuiting of the speaker terminals, for complete peace of mind. This power amplifier is the ultimate tool for immersive music enjoyment on the highest level.

Description

Accuphase P-4500

Overview

Since Accuphase started with the P-300 in 1973, the 50 year history of Accuphase Power Amplifiers has continued to evolve, with a wide range of variations such as Monophonic, Class-A and Class-AB. The Accuphase P-4500 is the successor to the P-4200 launched in 2013. This new model is a direct descendant of the first P-300. The P-4500 is a mighty entry level power amplifier that also gets very close to the audio performance of our flagship A-250.

P-4500 features best in class low noise and high damping factor performance. With the enhanced power output stage, the amplifier is able to perfectly drive modern high-end low impedance loud speakers.  Thanks to the massive power supply with built in headroom, new P4500 clearly expresses the dynamics and excitements of music sources, and it also offers the excellent performance in all kinds of environments.
