So, if the Auteur has a wonderful tuning, and it really sounds like it does based on the feedback, why would people not simply use as neutral tuned an amp as possible to allow the character of the headphone to shine through? I guess this effort will be beneficial specifically to people who agree with the extra sound tuning as applied by the amp (and I have no doubt that will be many people). I guess I shouldn't be surprised as this sounds like a natural progression of a completest who really digs what it is that Zach tries to convey in his signatures. This amp would simply be another expression of his sound reproduction ethos so I guess I have answered my own question.
