Keith,
In terms of burn in hours I'm not sure if there's a precise answer. I can tell you that based on my listening, there's a noticeable improvement around 60 hours. They surely continued to improve to the 100-120 hours range. I don't know how much it really matters, as they sound good early on and steadily improve. From the beginning they are clear, transparent and dynamic. With additional time they became increasing relaxed and organic while remaining very open and transparent. That's my experience with them. Different people will likely report various numbers of hours. One undeniable trait is superior lower level detail and nuance retrieval.
