Externally fitting with Wall Audios other audio components (azure blue display, Wall Audio typical simple and elegant design, remote volume control), our new preamplifier OPUS 88 has celebrated its premiere at the hi-fi days in Hamburg in February 2012.

Because of its special, unique sound quality and fine dynamics OPUS 88 became within a very short time an audience magnet whose presentations regularly made sure that the capacity of the projection room reached its limits.

In short: OPUS 88 is the perfect result of Wall Audios over 30 years of research and experience in the audio field.

One particular feature of this model is the technology of the rectifier tubes, otherwise the possibility of anode voltage regulation provides maximum clean power. Another important feature is the phono stage with MC / MM input, that pleases particularly analogue audiophiles.
