offers 2x20 watts of output power into a 6 ohm load
      combined with low output resistance (high damping
      factor). Such providing excellent drive capability for
      loudspeakers with medium to low efficiency or critical
      impedance behavior (which may present a challenge for
      our all-tube triode amplifiers) while offering  an ultimate
      sonic presentation without involving exotic and costly
      power tubes.
The amplifier is based on a unique minimalist
      single-ended zero-feedback vacuum tube MOSFET
      hybrid topology which we call EHT Topology
      (E/intakt H/ybrid T/riode, single-ended hybrid triode).
      The EHT topology allows to fully exploit and mate
      the most desirable characteristics of both
      vacuum tube and solid state devices
      determined by their very nature.
