On the topic of burn-in, I traded my burned-in V4 Magnum drivers (~200 hours maybe) with his fresh virgin (less than 5 hours... "virgin" enough) drivers and the new ones aren't as smooth as I remember these. I'm running through my gamut of songs, and there's a certain edginess that I don't remember these having. Maybe it's batch differences, maybe I drank too much coffee today, the low tide is throwing off my biological clock, or simply life is hard in the year of the dragon.

I do have two of them, so I'll burn one in for a couple of weeks and see if I can compare side-by-side.
