Pioneer PRS-D4200F

The Pioneer PRS-D4200F is a Premier class F/D amplifier based on an ICEpower circuit that outputs improved sound featuring tight bass with a minimal lag effect. The Pioneer PRS-D4200F is the only four-channel amplifier in the PRS series, but it is in direct competition with the four-channel 400w PRS-A900 ($1,499.95) from the Championship series, and the 600w GM-6300F ($199.95) from the GM series.

The Pioneer PRS-D4200F, however, offers an improved power handling of 1200w, an enhanced frequency of 10Hz-40kHz, and a superior signal-to-noise ratio of 100dB. The PRS-D4200F is priced at $499.95, a whopping $1000 savings from the PRS-A900. The reason for the price differentiation is because the PRS-D4200F lacks certain features like a copper-plated power transistor mount and an H-shaped chassis. Overall, the Pioneer PRS-D4200F is considered by critics to be a highly optimal choice for consumers seeking a high-powered, multi-channeled amplifier with almost the exact same functionality as the PRS-A900, but at a much more affordable price.
