DiBiQuadro - Harmonic distortion is an important part of the "magic" tucked into the very best pro recordings, mixes and masters. Of course, sampling and non-linear convolution also offer great results when it comes to capturing the "magic" of a particular hardware chain, but it's also a sort of a "take it or leave it" method of processing audio. If you like the character of that particular chain on that particular material, then it's worth to capture and use it; however, if you want to make changes, you have to look for another option.
