In the early 90's we moved from Soundstream, an absolute nightmare, to Audio Ease which, by comparison was great. If I recall the politics of it, they were bought out by the Harmon family and the powers that be closed Audio Ease to focus on Panja. Anyway, I haven't heard of anyone offering support. Fortunately the home run based wiring scheme would allow you to upgrade to Elan or something else.
