The noise performance of the P-7500 is remarkable compared with the former P-7300. With the state-of-art circuitry, the P-7500 improves noise level suppression by 11% over the previous model. The guaranteed S/N ratio achieves 130dB, the best value in the Accuphase Power Amp history.

Remote Sensing is the technique to lower the amplifier's output impedance by the negative feedback with signal sensing from nearby the speaker terminals. Balanced Remote Sensing is the technique to make the output impedance even lower by both the signal sensing and the GND sensing, that is, the negative feedback of the GND level. Not only the Damping Factor but also the Total Harmonic Distortion and Intermodulation Distortion are all improved by the Balanced Remote Sensing.

The P-7500 tidies up the very traditional design of the Accuphase power amplifier with massive and elegant impressions. The large analog “needle” meters which offer output power monitor and good visibility, are located in the front panel, They are high-sensitivity with the -50dB indicator, which allows you to enjoy the upbeat needle move even under the low volume operation. We also put the gain selector in the front panel, You can choose the appropriate gain level from the 4 settings, “Max, -3dB, -6dB, and -12dB.” This gain switching does not attenuate the signals with an attenuator. But it controls the gain at the input amplifier section, making the power amplifier section stable and reducing the residual noise when using the high-efficiency loudspeakers. We can simultaneously decrease the noise, which occurs when operating the unit under a low gain level. You can easily make a bi-wiring or bi-amping connection with the two large speaker terminals.

P-7500 has a mono-block construction. It contains an intense power supply with a massive special made high-efficiency toroidal transformer and two sizeable 60000μF special made filtering capacitors in the unit's center. In addition, the two power amplifier units are kept separate for the left and right channels.

Hihe P-7500 power amplification stage uses a 10-parallel push-pull power transistor architecture, providing a large current without the influence of impedance fluctuation of loudspeakers. The Gold-plated glass cloth fluorocarbon resin PCB helps to improve a lower impedance and reliability. The gold-plated big bus bars are on the paths where large current flows. They contribute to the further lower impedance for the circuits and allow ample output power to be transmitted to the loudspeakers.gh power design provides the rated output power of 300W/8Ω, 600W/4Ω, and 900W/2Ω that vastly exceeds conventional models, securing an overwhelming dynamic range.
