triodes, while the output is a SS pure Class-A bipolar power transistors current unit. This hybrid technology makes possible to have a direct output without using a transformer, and this way offer all the natural sound produced by the input tube stage without the slow sound, typical of the classic OTL tube amplifiers, we call this technology

"enhanced output transformer less" E-OTL. In the best of the tubes, work together with the best of the transistors a highly musical amplifier, the tube input stage gives to the sound the warmth of tubes without any artificial color, and the high current output can perfectly handle headphones of any impedance. response is almost flat from 2Hz ~ 50KHz (< 1db). The amp is cased in a heavy aluminum box. Wiring is made using only silver cables.

The harmonic distortion is reduced to a mere 0.2% at normal listening
