Hola and welcome. Well, I will choose the Electromotions. Fisrt of all, have the new design of the electrostatic panel. Also, they are easy to drive. My ears say, more dynamic sound, and a better sound stage. The Aeon i and Aeon are the last model of the old technology of the panel. The Aeon i comes wth a back tweeter for ambience sound. You can desable it if you want too. The Aeons are bigger in size, but the new panel has more contact with the air, about 40% more, so to me, the Electromotions are better speakers. The look of the Aeon i is nicer. The Electromotions won the nomination of product of the year from several magazines. You can read more at www.martinlogan.com
There is nothing wrong with the Aeon, Cinema, Scrip and Depth, only that they are old models and there had been some modifications from the factory, providing better specs and sound. You must listen first, because the speaker model have over 12 years by now. You must judge the sound, listening to them, first. Happy listening!
