The Millett Hybrid Maxed, or Millett MAX, or MAX for short, is a vacuum tube and solid state hybrid headphone amplifier. It is the latest refinement in a series of headphone amplifiers that began with Pete Millett, its namesake. This is a fantastic headphone amp. The design even includes vacuum tubes illumniated by blue LEDs!! Colin Toole is currently taking names and quantities for a group buy of the custom PCB designed for the MAX amp. The expected cost is $12, however, it could be less if enough people place orders. Orders can be placed until June 3rd. More than 253 have been spoken for so far.
