Product Highlights:

  • Traditional Class-AB reigns supreme for speaker amps and the Funk is a true-blue 45Watts per channel Class-AB. Powered by our proprietary Max Current Power Supply, it resets your perception of rhythm through power, precision and micro-details. It makes most conventional amplifiers, even the ones with twice the declared power, sound slow and dopey.
  • Fully discrete, Class-A, 3Wpc. Funk is also a vastly improved Burson Fun, which won Product-of-Year on Headfonia and loved by head-Fiers since 2017. It has higher resolution and power and infinitely sexier looking. IEM, no worries. Big cans, no sweat!
  • This insane size vs performance ratio is made possible by our proprietary Max Current Power Supply technology, which removed the need for heavy transformers and oversized power caps. It delivers instant and clean power directly to the output transistors. With two separate signal paths and each facilitating opamp rolling, you can tune the Funk to match your headphones and speakers separately.
  • Gaming headset compatibility, ticked. Soundcard connectivity, ticked. Movie night, game night, Funk it any way you like.
  • Touch and feel the Funk then our competition. The difference will be striking. Precision machined, this beautiful aluminum enclosure is also a unified heat-sink, keeping the Class-A headphone amp and Class-AB speaker amp running cool while looking hot.
