Accuphase-P-4600

Filled with the highest-quality technologies, the P-4600 Class AB stereo power amplifier provides supreme driving performance. The power amp stage features 6-parallel push-pull power transistors, while its rated output of 150 W into 8 ohms dwarfs conventional models. Combined with an S/N ratio of 125 dB and a damping factor of 800, it drives large speakers with ease and creates a rich, deep soundscape. The P-4600 power amplifier extracts the complete breadth of recordings, vividly recreating the rush of live performances, and lets you enjoy the very essence of musical performances.
