Inner Sound Eros Experiences

Can anyone tell me about their experiences with Inner Sound? I'm considering a pair. Will they play loud vs. Magnepan 3.6? What electronics do you use? Is the set up more picky then a Magnepan 3.6? Reliability? Company status? How big of a sweet spot vs. MG 3.6rs? Is the company more custy friendly than Magnepan?
