Wall Audio OPUS 33 SET Integrated Tube Amplifier

An amplifier for all your senses – single-ended triode (SET) topology.

The SET (single ended triode) – OPUS 33 SET amplifier uses no feedback and usually works in Class A, but offers the feature called ECO Mode.

If the user listens to music from a source such as radio, television, mp3-player or internet, it is possible to switch from Class A to Class B using the ECO button. This affects energy saving and increases the life (emission) and performance of the tubes, which are less heavily used in this mode.

Special features:

  • Point to Point Technology
  • Internal silver ribbon insulated wiring
  • No global or local feedback
  • Automatic stabilized bias current of power tube
  • Hand-made in Germany
