Because you cannot ascertain by looking at a spreadsheet which of two amplifiers you will prefer. The only way to know what anything sounds like is to listen to it. With your ears. Measurements exist to determine what may work within a system, and what may not. Think power characteristics for an amplifier and the power demands for a set of speakers. If you own speakers that require a lot of power, that require a high dampening factor, a low powered amplifier, with a low dampening factor, will likely not drive your speakers to their full potential. But once you find two amplifiers that will drive your speakers according to the numbers, you still need to listen to those two amplifiers, in your system driving your speakers, if you want to know which amplifier sounds best, to you. Measurements are a tool, they are not an end.
