Step into a world of refined sound with the Accuphase P-7500 Stereo Power Amplifier, an outstanding representation of Accuphase’s premier Class AB stereo power amplifier line. The P-7500, with its meticulous engineering, harnesses a 10-parallel push-pull power transistor design in its power amplification stage, boasting an awe-inspiring rated output power of 300 W / 8 ohms, which notably overshadows conventional models. The remarkable signal-to-noise ratio of 130 dB coupled with a damping factor of 1,000, empowers it to effortlessly manage large speakers, delivering dynamic and colorful musical output. With the P-7500 at the helm, any speaker’s performance is notably elevated, unveiling a landscape of sonic possibilities awaiting exploration.

Delving a bit into the technical sophistication, the balanced input stage of the P-7500 is a piece of art. It adopts an instrumentation amplifier topology, a characteristic found in high-precision measuring gadgets, aimed at achieving an incredibly low noise level. To realize this, the input stage gain has been calibrated to a higher value, allowing for the employment of a high-power supply voltage. This meticulous arrangement effectively tackles distortion at high amplitudes. The narrative of signal purity gets a significant boost with the integration of premium-quality discrete components, amplifying the overall superior performance of this amplifier. While it might seem like a lot to digest, a simple chat with our folks at Soundlux Audio can shed more light on how these technical details translate to an unparalleled audio experience.

The ingenuity doesn’t stop there; Accuphase’s unique MCS (Multiple Circuit Summing) principle is the heartbeat of the P-7500’s exceptional performance. This principle engages multiple identical circuits in parallel to harness superior performance attributes. The story takes a twist with the introduction of MCS+, an enhanced version that extends this parallel operation concept to the class-A drive stage of the current/voltage converter. This ingenious advancement significantly trims down the noise floor, propelling the amplifier’s overall performance and sound quality to a higher grade. The complexity yet elegance of the P-7500 might incite curiosity, and who better to reveal this than the technical cleverness at Accuphase?

Now, shifting focus to the output stage, the P-7500 flaunts a 10-parallel push-pull power configuration with bipolar power transistors, securely mounted onto a robust die-cast aluminum heat sink for efficient heat dissipation. This stage smartly incorporates MCS+ circuitry and a current feedback amplifier, enhancing performance remarkably. The design places two completely identical units on either side to achieve optimal audio output and balanced operation—a harmonious blend of symmetry and functionality.
