DENMARK · HIGH-POWER AMPLIFICATION · BY JAN HARBO JAKOBSEN
“Why is high-end audio too expensive? Even when I calculated worker salary, buildings, and brand value, I still could not make it add up. That is why I founded Danish Audio Design Int. Music should be less about money and more about feelings, emotions, joy, pain, dance…”
— Jan Harbo Jakobsen, Founder
The Only One SE

This power amplifier never gets warm or overheats — even when running the largest loudspeakers for hours. Due to the extreme build quality and choice of components, you experience dynamics and music reproduced in a manner that makes it hard to separate reality from recording. The decoupling capacitors used here are also used in high-speed trains in Japan.
The amplifier profiles are not cheap ribs — each side panel is cut from a single piece of metal by a modern CNC milling machine. It takes more than 12 hours just to machine one side. The power transformer is wound from 100kg of toroidal core, limited to 50A. Stable down to 0.5Ω.
