Wall Audio Opus 88 - tube preamp with MM/MC phone stage - hand made in Germany

This is a demo unit used in our showroom. It’s in excellent condition and comes with original box, remote control and warranty. This unit is for 120V only.

Wall Audio is a company in Freiburg, in the south of Germany, making tube amps since more than 30 years and finally available in the US.

The Wall Audio Opus 88 is a great sounding preamp. It delivers a full, rich, lush sound with deep and wide soundstage and great dynamics and speed. The Opus 88 employs altogether 14 tubes. The transformer is externally housed to prevent electromagnetic field interference to the tubes, which is very smart design. Even the rectifier and power supply tubes are separated from the over-dimensioned, cast-in transformer.  

Amre Ibrahim, Image Hifi (April 2015):
"...I don’t know of any other pre-amp in the price range under $6000 that has been produced with such high quality work, parts and careful attention to detail. The resulting sound proves that the designer is right. If you’re searching for an honest, affordable pre-amp, don’t have a huge fleet of components in your system, call vinyl your own and - if you value the sound of dynamics and neutrality,  but still don’t want to give up a touch of tubes, then you should definitely put the Wall Audio Opus 88 on the shortlist of your candidates. If you don’t, you’re making a mistake..." Check out the entire review

Thomas Schmidt, LP-Magazin:
"...consistently build a tube preamp as it should be, superbly equipped and of course with a magnificent and glorious sound especially in the phono stage... Thank you for this tip!" Click here to read the entire review

More information from the website:

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.
