Our motivation and mission is to eliminate all technical barriers that prevent the enjoyment of reproduced music. We prioritize addressing the biggest limitations first and move on to the next. Currently, our research and development efforts are focused on loudspeaker transducers, which are the most significant overall quality limitation, and the audio power amplifier, which has traditionally been the weakest link in the electronics chain.
Our methods and principles emphasize the importance of thoroughly understanding the problems we encounter before attempting to solve them. We value the development and verification of accurate mathematical models, which enable fast virtual prototyping and 'fail-fast-forward' approaches. Our approach is to build what we simulate and simulate what we build. We have a deep understanding of analog and digital systems, as well as all domains of electromagnetics, mechanics, and acoustics.
We believe that all that matters for the sound quality can be measured although we often have to develop new measurement methods that are indicative of the subjective sound quality.
We direct all R&D efforts on such measurable metrics. If this does not agree with the listening results we improve our objective metrics.
