Kal Rubinson has posted a review of the Illusonic Immersive audio processor ($21,300) in his Music in the Round column at Stereophile. His conclusions:

Its unique feature set will appeal to sophisticated users who know exactly what they want from their systems: the ability to implement flexible and complex speaker arrangements, a graphic user interface with real-time configuration operations, an effective parametric equalizer, and outstanding overall sound quality. ”
