Pioneer Championship PRS-A900
Released April, 2008
The Pioneer Championship PRS-A900 is a Premier four-channel bridgeable amplifier with a filter-less design for improved sound, reduced distortion, and the elimination of vibration and noise. Part of Pioneer’s ‘The Power’ Championship series, the PRS-A900 is in fact the most expensive multi-channel amplifier that Pioneer offers, and also the only multi-channel amp in the Championship series.

An upgrade from the PRS-D4200F (from the PRS series), the PRS-A900 offers reduced harmonic distortion (<0.003% versus 0.005%). However, the PRS-A900 sports a weaker power (400w versus 1200w) and an inferior frequency (10Hz-100kHz versus 10Hz-40kHz). The reason that the $1499.95 Championship PRS-A900 (versus $499.95) is cited an upgrade is because of its inclusion of more features versus the PRS-D4200F. For instance, the Championship PRS-A900 features copper-plated power transistor mounts that eliminate vibration and noise, an H-shaped chassis that helps stabilize the amplifier by absorbing vibrations, and left/right channel power independence cited as directing electric current with ‘superior stability and effectiveness.’
