Actually, I think that may have been me. I bought my summits from an audiophile who had them for a year or so, and I passed along that he told me he felt they weren't fully broken in until about 500 hours. From everything else I've read about the summits, I think you're probably going to get 90% of the break-in after about 200 hours.As I red somewhere here, it takes 500 hours to break them in?
