It is about making something to last, and live with. About bringing music into sound.

And yes, they say it is a high challenge. For a reason. It means conveying not only high resolution content all through the audio band and three dimensional sound picture, but also natural, organic and textured tone and scale.

And being at the cutting edge is about abandoning compromises, and about thoroughly thinking every part of design. It takes brave ideas, and development involving extensive measurements at one, and actual and continuous music listening at the other side. So, not listening tests, but every day listening. Reality check.

That’s how Audial devices are made. And they indeed produce unique experience, just as real works of art do, that is equally exciting and pleasurable.
