Accuphase P-4500
This Accuphase P-4500 has led a quiet and sheltered life. Generally, it’s been wheeled out to show the differences between the more expensive Accuphase Class A and A/B offerings.
This is an absolute cracker of a power amp and it sounds terrific with the new C-2300 preamp.
As one from the A/B camp, the Accuphase P-4500 has masses of power and offers great dynamics and serious headroom whilst also being very refined indeed.
This dates to November 2021. Never travelled, infrequently played, fully warranted for 12 months and supplied in the (unusually excellent) original Accuphase packaging.

RRP £8000, but we’re not supposed to tell you that . . .
The quest for the optimal power amplifier has just taken another giant leap forward. The P-4500 features an instrumentation amplifier configuration realized with discrete semiconductors in the signal path, triple Darlington 4-parallel complementary push-pull architecture and many other technology advantages. The result is an impressive S/N ratio of 121 dB, rated output of 500 watts into 1 ohm (music signals), and a damping factor of 700. A newly developed output protection circuit can also detect any short-circuiting of the speaker terminals, for complete peace of mind. This power amplifier is the ultimate tool for immersive music enjoyment on the highest level.
