About the SET 100 Ultimate
SET 100 Ultimate is a 120 W single-ended class A hybrid amplifier. It has the magic midrange of a small SET amplifier, combined with scale, authority and macro and micro detail.
It uses a specially designed single-ended MOSFET output stage, direct-coupled at the output with a double C-core amorphous choke as the DC current path. With only two gain stages and no overall feedback, distortion stays low while the output impedance is low enough to drive real-world loudspeakers.
The first stage uses a Siemens EC8010 high-transconductance triode, chosen for its sound and reliability, powered by a separate supply with tube rectification and choke regulation. It is coupled to the output stage by a state-of-the-art interstage transformer with a proprietary double C-core and an optimised winding design.
The output stage, power supply and all internal wiring are hard-wired with silver wire extruded to Ypsilon's specification. The power supply uses a low-noise E-I transformer, a large choke and four-pole electrolytic capacitors, giving a very quiet, dark background from which the music emerges.
