Considering the fact that all three of these amps have a different power output, until you somehow, can get them to output at "exactly" equal moderate volume for your source material and can instantaneously switch between them, any realistic comparison is going to be difficult. I dunno, but, it always comes back to the same old story in these comparisons that if one of them is even slightly louder than the other, to the human ear it is going to be perceived as sounding "better" or at minimum, "different". For that reason alone and considering that this is such mature technology, I, personally, have never bought the idea that there is a "real" audible difference between various brands.
