Thanks Monte.
Tony licensed his Annapurna circuit to Mojo Audio and we'll be manufacturing a production version of the headphone pre amp in early 2018.
He'll still be making the over-the-top custom wooden ones and we'll be making the same amp with the same circuit using more modest component parts in a more modest all aluminum chassis.
At RMAF'18 we plan on having a room filled with all production Annapurna amps, our new server and DAC, and some of the world's best $2K-$6K headphones.
BTW, Audiophilia just reviewed my Mystique v3 DAC and awarded it "Star Component":
