Audio Matiere paraphrase in wonderful condition. Audio Matiere was designed and owner by Jean Jacque Van Leeuween a former designer at Jadis. During his time at Audio Matiere he designed some of the best tube gear to hit the US in Mid 90s. I am the original owner of this glorious piece of audio history. I recently returned this preamp to Marigo Audio labs fo a complete check up. The Unit functions perfectly and gives you a taste of the Jadis glorious sound at a fraction of the cost. I have the original wood crate and packing materials for safe shipping. This unit in in nearly perfect condition.. definitely collector worthy. I also have the matching Equilibre amp if someone wanted both. Very nice. Will consider trades as well.
