The PRAUTES is primarily a headphone amplifier, although it can also power small speakers and provides a line-out stage. The controls are optimized for headphone output and the result is an unbelievable clarity, presence and expansive soundstage. The PRAUTES drives a wide range of headphone types and provides for impedance matching. A very subtle bass boost feature is included.

PRAUTES defined: understood to be a reference to proper understanding and accurate action. PRAUTES AS DEFINED BY THE ANCIENT GREEKS expresses a character in which strength and gentleness are perfectly combined. The PRAUTES amplifier seeks to do just that—present music in a manner that delivers subtlety, image, detail, and excitement, all in an accurate manner that duplicates the live experience. The Prautes amplifier combines vintage tubes, military technology, and hand made USA components to create the ‘PRAUTES’ experience. The result is a legacy piece—one that is timeless and enduring.

The PRAUTES uses a 12AU7 tube gain stage to drive a pair of 50L6 tubes in push-pull mode. This provides for more power than needed for almost all headphones—and can drive high efficiency speakers with about 2 watts. Five separate output impedance settings are provided to match listening equipment, including 8 ohm speakers, standard headphones, high impedance headphones and In-Ear-Monitors.

The PRAUTES amplifier bears the signature of Damon Coffman. He trained in college as a concert violinist, obtained his graduate degree in physics through the U.S. Naval Postgraduate School, then built his career as an engineer in medical technology firms. While pioneering new technologies for medical companies, Damon began searching for audio equipment that would give his favorite pieces of music the beauty of a live performance. He found some of what he was looking for in the designs of classic amplifiers from the golden age of analog audio. He then combined his passion for music, art, and craft into heirloom quality products that embody his design philosophy of simplicity, elegance, and accessibility.

We are proud of our unique approach to audio and design, and we believe that our amplifiers will be enjoyed and cherished for many years to come.
