just to give you a bit of correct history. The only patent issue Magnepan had with Apogee Acoustics was with regard to the Apogee DIVA ribbon tweeter. This was circumvented by backdating the serial numbers on the DIVAs. Apogee did not go out of Business because of Magnepan. I have/had contacts to the inner circles of ex-apogee and the story was the high competition and demand for more commercial speaker systems. The downfall came with the Apogee GRAND. The engineering and production cost were to high and the numbers sold too low. Had nothing to do with Magnepan. The models that Magnepan has/had only employ in some cases an actual ribbon. Just for history purposes i have/had several models from both companies Apogee (Caliper Sig, Scintilla, Stage, DIVA and The Grand) as well as Magnepan 0.5, 1.6 and two pairs of 3.6s.
