No, mafia996630, you don't see how a keygen works.
You see, a keygen does just what it implies - it generates keys. It generates keys according to a hash that's been reverse-engineered or stolen from the software maker. In theory, it works really well, but the precaution software makers have have taken the last decade is to keep an on-line database of all the keys they've given out. If your key doesn't match one of those, it won't work. And that is where the keygens fail, as they have no way of knowing the accepted keys.
The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. -
