Accuphase · P Series
The P-7500 is Accuphase's flagship Class AB stereo power amplifier: 300 watts per channel into 8 ohms, 600 into 4 and 900 into 2 from a ten-parallel push-pull output stage, with a damping factor over 1,000 and 130 dB signal-to-noise.
Price is for one unit.

The story
Where the P-4600 covers most systems, the P-7500 is for speakers that need more. Each channel has ten parallel push-pull power transistors in a three-stage Darlington configuration, driven in Class AB and arranged as an instrumentation amplifier with balanced inputs, behind a large toroidal transformer and 60,000 µF of filter capacitance. The result is 300 watts into 8 ohms that rises to 600 into 4 and 900 into 2 on music signals, or 1,200 and 1,800 watts in bridged mono. The MCS+ parallel voltage stage, current-feedback topology and balanced remote sensing deliver a damping factor above 1,000 and 130 dB signal-to-noise.
MOS-FET switches with no mechanical contacts handle protection and output switching, a four-position gain selector (28, 25, 22 and 16 dB) matches any preamplifier, and bi-amp and bridged modes are built in. The power meters, edgewise coils and 108-pound chassis are classic Accuphase. In front of it, the C-2300 or C-3900S; it will drive anything in our showroom.
Accuphase builds every component in a single finish, so there is nothing to choose. The champagne-gold front panel has been the house signature since 1972. The top plate is hairline-finished aluminum.

The most powerful Accuphase stereo amplifier. The P-4600 is the smaller Class AB design; the A-80 and A-300 are pure Class A.
Pair it with the C-2300 or C-3900S. Two P-7500s bridged give 1,200 watts per channel.
