DNA Supernaut vacuum tube headphone amplifier

The inspiration for creating the Supernaut lies in the magic of the KT66. When I built an amp using the tube triode-wired, my first thought upon listening was, "this has the clarity of the 45", which is another one of my favorites and regarded as one of the best DHTs of all time. I then set out to develop a headphone amp around the KT66, maximizing its sonic strengths while delivering a fun, engaging, and musical listening experience. The amp pairs great with dynamics from ZMF, Sennheiser, and has a super-low noise floor for sensitive headphones like the Utopia.

Design features include:

• Purist class A single ended triode design

• Custom Audio Note UK output transformers

• Flat and extended frequency response

• Zero feedback or other error correction trickery
Triodes are naturally low distortion when operated into a high impedance load such as a transformer with proper specifications. They do not require feedback to attain low distortion.

• Point-to-point hand wired audio circuitry using carefully selected audiophile components

• TKD volume control potentiometer

• Choke-filtered high tension power supply with separate filter capacitors for left and right channels

• Individual choke-filtered DC heater supplies

• 1 pair RCA unbalanced inputs

• 4-pin XLR and 1/4" stereo TRS outputs

• XLR and 1/4" TRS outputs provide the same power: 1.8W into 50 ohms, 900mW into 100 ohms

• XLR output is selectable between unbalanced (single ended) and balanced headphone drive

• XLR output has 11 ohm output impedance

• 1/4" stereo TRS output has selectable gain attenuation between 0dB and -6dB for greater volume control range on higher sensitivity headphones

• 1/4" stereo TRS output on full gain, 0dB attenuation setting has selectable output impedance between 11 ohm (Low setting) and 120 ohm (IEC setting)

• 1/4" stereo TRS output on -6dB gain attenuation setting has selectable output impedance between 6 ohm (Low setting) and 116 ohm (IEC setting)

• 17dB gain

• Tube complement:

6CG7/6FQ7 input/driver tube
KT66 triode-wired output tubes
5U4G rectifier tube

Input impedance: 50Kohms
