I owned both, I loved both. The changes arent as significant as people think. They're both quite sub bass heavy, with sparkly treble, and mids that are slightly recessed, but unhampered by mid bass.
If the lawton pads attempt to reduce bass, it's an absolute failure to me. Why the hell would anyone try to take away what makes Denons...Denons? Get an LCD2 if you want better mids while retaining some (SOME) good bass.
Nothing can touch the D7000 to me. The fact everyone says the two new Fostex have less bass, means they aren't as memorable to me.
Sounds to me like your ears are subconsciously thriving for the D7000's bass!
I wish I was lucky enough to try them... let alone afford them.
