This has always been a topic of interest for me, given the typical credence burn-in recieves when people listen to two headphones of the same model that sound slightly different (one new, and one old) - they usually say to themselves, after having been exposed to talk of the phenomenon of burn-in, that the sonic differences are an obvious result of burn-in and it's proof that it occurs. However, that's not the case at all, for the simple reasons I've stated above. It's something to keep in mind as well when deciding what to buy, as more closely matched drivers are inevitably going to sound more pleasing to the ear!
The SR-225 uses the same driver as the SR-125, but employs 0.05dB closer driver matching and has better airflow in the chamber.
The HD600 uses the same drivers as the HD580, but employs (substantially) closer driver matching and supposedly has a slightly differently tuned enclosure (not sure how much I buy that, to be honest; it'd have to be awfully minute, as you can open it up and measure it yourself and it looks/measures awfully similar).
