Innovative

We like to find new or better solutions for existing needs. This implies developing new and creative ideas. No other feeling is comparable to when real innovation is reached.

Evocative

We love new and we love vintage. In our search for the next big thing sometimes we encounter little audio treasures from the past that need to be brought back in digital form.

Affordable

We don't inflate our prices just to give a "more premium" feel.
All of our products are reasonably priced, taking into account the time and dedication we put on each.
