Well... I'm leaving the D7000 alone (until I hear aamefford's with the J$'s on them in Feb).
I think they are just amazing as is and won't believe there can be an improvement until I experience it first hand.
I had the LA2000 Lites. I had the D5000. Sorry, but I did not care for what the LA mods did for the sound. It did decrease the bass bloat (of the D5k), however. For me the D7k has no bass bloat, so no need to mod them.
