RE: N core

I am at a loss as to why you think I don't grasp such a basic concept and it is widely known that you didn't come up with it. Whether it is a worthy goal or not in the abstract is not much in debate...all amps should strive for the max linearity...according to the listeners. This is not as subjective as you think as there have reasonable attempts to correlate listener preference with distortion. It turns out to not be what most meter readers expect. The reason being the typical strategy for lowering distortion seems to introduce other issues, the most obvious being reduction of low order harmonics at the expense of making many more, sonically damaging high order harmonics. In other words the PATH to lower distortion is arguably more important than magnitude of the reduction. The impact is highly non-linear.

Linearity according to the scope is not weighted for the impact of those residual distortions on the listeners. Cheever and Geddes both came up with exponential weighting with increasing harmonic order. Once accounted for there is a big change in ranking for sonic "straight wire".
