I have recently purchased a pair of Helicon 800. I drive them with Sim Audio P3/W3 combo. Yes they did sound a bit bright in the beginning but that is all gone now after I have listened to them for more than 150hours or so. Also, it was never a problem with Analog front end but only while listening to some CD's, mostly of the pop genre. I've replaced a pair of Dynaudio 1.3SE plus REL subwoofer with the Dali's and must admit that they are a big step ahead especially if it comes to Sound Stage. The Dyn's were almost to much with their imaging qualities, the Dali's are more like a live event. I would recommend them highly.
