The P-588 is a stereo power amplifier from Accuphase, a Japanese manufacturer with a considerable reputation for uncompromising high-end electronics engineering, built with a substantial power-doubling relationship and considerable gain. The P-588 brings Accuphase's meticulous engineering to two-channel power amplification.
Key specs that matter
Input impedance is 11k ohms single-ended. Output power is a substantial 300W into 8 ohms, doubling cleanly to 600W into 4 ohms - a textbook power doubling indicating a robust, well-regulated power supply. Gain is a substantial 34dBu. Total harmonic distortion plus noise is an exceptionally low 0.006% with full global feedback. At 440 x 430 x 118mm and 20.8kg, the P-588 represents a substantial stereo amplifier commitment reflecting Accuphase's characteristic build-quality standards.
Sound and use context
Expect substantial power delivery combined with exceptionally clean measured performance reflecting the sub-0.006% distortion figure and the clean power doubling into 4 ohms, consistent with Accuphase's broader uncompromising Japanese engineering standards.
Pairing
The clean power doubling into 4 ohms suits a wide range of loudspeaker impedances, and Accuphase's own C-2150 or C-2300 preamplifiers share the brand's coherent engineering philosophy.
Alternatives
Accuphase's broader amplifier catalogue offers alternatives for buyers wanting a different output level.
