I would look at magnapan 1.6 or 3.6 speakers or soundlab electrostats if you want to go the dipolar planar route. Otherwise you might want to take a look at Hyperion speakers (great reviews). I don't know what the future of innersound will be without its founder, who I believe left the company, so while their speakers (& electronics) were superb future service etc may be a problem. I always thought that the innersound electrostats and the soundlab electrostats out performed martin logan's offerings but that is just my particular preference as ML still makes very fine speakers and is a company that should be around for some time.
