Big Amps, Big Power Done Right. PBN is pretty well known for Peters Noerbek's wide range of speakers, a pair of M2!5s which I recently reviewed (HERE) took up floor space at my home for the majority of this review.

Prologue: A Berning Desire Many years ago, I purchased a boxy little bespoke headphone amp for my Sennheiser HD600's called a MicroZOTL.
