Key Features  

• Class AB Power Output: Delivers 300W per channel into 8 ohms, 600W into 4 ohms, 900W into 2 ohms, and 1,200W into 1 ohm, ensuring robust power for the most demanding speakers.  
• 10-Parallel Push-Pull Output: Ten parallel push-pull power MOS-FETs per channel, mounted on massive heatsinks, provide high-current amplification for dynamic, distortion-free sound.  
• MCS+ Circuitry: Multiple Circuit Summation enhances signal purity, reducing noise for a transparent, detailed soundstage.  
• Ultra-High Damping Factor (1,000): Optimized MOS-FET switches with ultra-low on-resistance and refined signal paths ensure precise control, delivering tight, articulate bass.  
• Robust Power Supply: Dual high-efficiency toroidal transformers and four 82,000μF filtering capacitors (328,000μF total) provide stable, clean power for high-current demands.  
• Balanced Input Stage: Fully balanced instrumentation amplifier with current feedback minimizes interference, ensuring pristine audio with excellent phase accuracy.  
• Versatile Connectivity: Includes 1 RCA unbalanced and 1 XLR balanced input per channel, with speaker terminals supporting A/B configurations and bi-wiring.  
• Advanced Protection: MOS-FET-based circuitry protects against short-circuiting, DC voltage, and overheating, ensuring reliability without relay contact resistance.  
• Bridged Mono Operation: Configurable as a monoblock, delivering 1,200W into 8 ohms, 1,800W into 4 ohms, and 2,400W into 2 ohms for high-power setups (1 ohm not guaranteed in bridged mode).  
• Elegant Design: Champagne gold panel, backlit VU meters with adjustable brightness, and a robust 50kg chassis reflect Accuphase’s premium craftsmanship.

Why Choose the Accuphase P-7500?

The P-7500 is a showcase of Accuphase’s engineering prowess, blending immense power with musical finesse, as praised by Fidelity Magazine for its linearity and light-footedness. Its 10-parallel MOS-FET stage and enhanced MCS+ circuitry deliver a signal-to-noise ratio of 130 dB, ensuring a noise-free, energetic sound that drives even the most exotic speakers with ease. Users report transformative bass performance, with comments like “bass comes out of the cabinets” when paired with speakers like Legacy Focus SE. While some note confusion in literature about 1 ohm music signals (rated for 2–16 ohms continuous), the P-7500’s 33A output transistors handle difficult loads effortlessly. With bridged mono capability, handcrafted Japanese build quality, and a serene, functional design, the P-7500 rivals top-tier amplifiers, making it a future-proof investment for high-end audio systems.
