After years of research and development Diesis Audio decided to design a hybrid-integrated amplifier. You have to admit that it looks awesome. Evento 20-11 uses a preamp based on two E88CC NOS tubes. Further down we have an oversized power supply in the power amplifier section allowing the delivery of 80 W at 8 ohms with high current capability. All of this in a beautiful non-magnetic cabinet. Italian company also offers the option to add a phono stage or a DAC card. Photo by Diesis Audio.
