PA1 premiere at the Vienna High End show

May 18, 2026

With only a few weeks to go before the Vienna High-End show, our team is working very hard to get everything fully prepared. At this show, we introduce our new mono block Power Amplifier, aptly named “PA1”, and it’s time to lift a corner of the veil.

An early prototype of the PA1 was secretly used when we presented the MU2 streaming DAC & pre-amp, three years ago in Munich. At the time we searched for an amplifier that was transparent enough to demonstrate the unique qualities of the MU2. Many amps we auditioned disappointed us. Eventually we decided to bring the prototypes of our own design that we had used during the development of the MU2. And we knew what our next big project would be…

The unusual setup in Munich impressed many visitors and we were even rewarded with a “Best Sound of Show” award. For the PA1 amplifier design we took the concept of our prototype even further. Numerous listening tests were performed and various improvements found their way into the schematics. The PA1 is now a serious step up in sound quality from our prototype, so you can imagine at what level it plays…

Of course the industrial design had to become something special too. We asked Michiel Uylings of MU1, MU2 and PW1 fame to draw his ‘mono block’ statement and it’s become a real gem.

This time the MU2 will take the servant role and be the source and pre-amp for our PA1. Needless to say that the aspects that make the MU2 such a unique musically and emotionally involving piece of equipment are also taken into account in the PA1 design. Some technical backgrounds of the MU2 quality can be found in this blog. Imagine a full signal chain where all these aspects add-up in bringing the music to your ears…

Stay tuned as we will reveal some more details in a later blog.

The major online publication Stereonet published a great review of the MU2 by author Eric Teh. He was highly impressed by what he heard. In contrast with many other hi-fi components, the MU2 made him feel connected to music in stead of technology. Stereonet therefore offered the MU2 their highest recognition, the Applause award.
