I have some questions about Martin Logan - DISREGUARDING the price. We will be selling them (99% sure), so that is not an issue. Questions on them: -Are they as inefficent as they are said to be? -I know the sound is very spacy, but still focused and clear, is this accurate? -Anything I should know about them? -Would a Denon 3805 die driving something like the Aeon i? -With proper power, will the mid-range models play loud, or are they 'quiet' speakers? Thanks! I know they have a great reputation, but don't know about the technical stuff.
