Isn't Korg more of a pro/musical instruments division
company?
Yes, it is. I'd have some skepticism regarding the potential for this technology to be well received in high end audio. Which is reinforced in my mind by the reference to vacuum fluorescent display technology that it draws upon, and also by the reference to generation of "the same rich harmonics that are distinctive of conventional vacuum tubes." The latter often being very different in degree for musical instrument applications than what most would consider to be desirable in a home audio system, where one would presumably/usually want to reproduce those harmonics as they were originally recorded.
But we shall see, of course.
