Glad to see this discussion motoring right along. I want to echo david_ten's observations on break-in. It took my Double Impacts at least 300-400 hours to reach their peak, and I am finding that the SEs are taking just as long or longer. Unfortunately, they were going through a "down" phase when Dan (kebouchard84) came by for an audition a couple of weeks ago, resulting in some looseness and lack of definition and impact in the bass and some stridency in the upper frequencies, especially on some recordings. For a few days, I found it difficult to listen to much of anything but acoustic, very well-recorded music. I had warned him in advance that they were still fairly early in the break-in process and that the sound would be unpredictable. Of course, he can speak for himself if he chooses, but I think he heard the potential in the speakers in spite of these issues. He spoke glowingly of his audition of the Double Impacts at grey9hound's place.
My SEs are sounding much improved now, glorious at times. Given my experience with the Double Impacts, I know this story will have a happy ending, though there is still some distance yet to travel. In some cases with these speakers, much patience is required, but the pay-off is extraordinary. Until then, it's a bit of a roller coaster ride, at least for some of us. The good news is that you do get glimpses of their greatness along the way.
