I don't think burn in will make any appreciable changes.
I have a 6400, with 8400 memory pads, and it's definitely a subdued, neutral phone that needs a little more power than the specs would seem to suggest. It tends to be a little grainy sounding at lower volumes, too.
It's a decent headphone imo, but from what you write I imagine that you'd be happier with something that has a different sound signature and a relatively large soundstage.
I found that the KRK KNS 8400 has a very good soundstage for a closed headphone but it is one of those... strange soundstages. It is difficult to explain but appreciating the 8400 seems to depend on being able to 'forget' that you are listening to a headphone and just visualizing that the sound is coming from outside. Somehow, the imaging seems to improve when this happens and I think I get KRK's philosophy behind this. With this said, I personally sold my 8400 due to its 'farty' bass. The bass is very clear, but lacks impact. Due to this, while we can easily hear the bass texture, it is not being 'filled out' with impact and thus the result is a bass that sound a little like a fart :)
I finally know what's wrong with these.
