Description
Accuphase P-7500 Class AB Stereo Power Amplifier
Flagship Power, Unmatched Control
The P-7500 stands as Accuphase’s flagship Class AB stereo power amplifier, delivering overwhelming driving power and precision. With a formidable 10-parallel push-pull transistor configuration, it outputs 300 W into 8 ohms, 600 W into 4 ohms, and 900 W into 2 ohms—ensuring effortless control over even the most demanding loudspeakers. The exceptional 130 dB signal-to-noise ratio and damping factor of 1,000 reflect the P-7500’s ability to deliver power with finesse, clarity, and absolute authority.
Engineered for Musical Expression
At the heart of the P-7500 lies a fully discrete input stage built on the instrumentation amplifier principle. It employs current feedback amplification circuits and Balanced Remote Sensing to deliver exceptional speed and accuracy while preserving tonal nuance. The MCS+ circuit enhances stability, and the amplifier’s protection system safeguards both your music and your speakers, all without interrupting the signal path with mechanical relays.
Precision, Style, and Versatility
With its large, responsive analog power meters, elegant aluminum chassis, and robust internal construction, the P-7500 offers both technical refinement and visual appeal. It supports bi-amping and bridged connections for advanced system configurations, making it the ideal choice for audiophiles seeking sonic realism, dynamic headroom, and musical depth in one powerful unit.
