[QUOTE="Jcsaudio, post: 8644579, member: 673752"] I swapped a Pioneer PRS 4200 Amplifier with its budget cousin that cost half as much. Both are class D, both are 75 watts rms x 4. I could not tell a difference in sound between the two. I did however notice a huge different in output between an old 25 year old Alpine amplifier and a new for the time (2014) Kenwood Amplifier of the same rated power. I suspected that difference was because the Alpine was under rated, but not sure. Added note, the Alpine vs Kenwood were both 2 channel amps bridged to drive a W3v3 8” subwoofer. The difference was the Kenwood sounded flat and lifeless and the Alpine lively and dynamic. I also noticed this when I compared that Alpine to my NVX mini mono amp. Again the Alpine sounded lively and dynamic vs the NVX that sounded flat. The NVX is rated 200 watts rms vs 160 for the Alpine. The gains were set using the DVM method and the results are repeatable. My advice is to get the best amplifier your budget allows but also get an amplifier that puts out 125% - 150% of the power you really need, especially with subwoofers. [/QUOTE]
