Accuphase P-7500 Class AB Stereo Power Amplifier
The P-7500 is our flagship model Class AB stereo power amplifier that provides supreme driving performance. The power amplification stage uses a 10-parallel push-pull power transistor architecture, providing a rated output power of 300 W / 8 ohms that vastly exceeds that of conventional models. Boasting an impressive signal-to-noise ratio of 130 dB and a damping factor of 1,000, it can effortlessly drive massive speakers and create musical recreations overflowing with energy. The P-7500 brings out the best of any speaker, allowing you to enjoy never-before experienced soundscapes.
