OPUS 34 Tube Amplifier

An amplifier that invites you to surrender the sound experience and that already counts among audiophiles to the legends of the future.

The OPUS 34 in various ways is as a great innovation in the field of tube technology. A completely new safety standard results from a closed cabinet – although the possibility to switch on or off the resonance (feedback), using a simple push button on the front, shows its great adaptability.
