Still I found the LA7000 doesn't match the TH900 in terms of refinement. The Fostex is still much cleaner-sounding, with better clarity and detail. Also the Fostex clobbers the LA7000 for me in imaging and spatial reproduction.
One thing to keep in mind is that the Lawton mods aren't cheap unless you do them yourself. You'd end up spending as much as it costs for the stock Fostex TH600 and even the TH900 with some of those cable options.
So far with initial impressions, I tend to agree. The Denon's... even modded can't touch the detail retrieval, soundstage, imaging, and instrument separation that the TH-900 has. I did find a nice upgrade over the stock D7K, after hearing a LA7000, but those changes were only in regards to the sound frequency. The other characteristics that make the TH-900 a reference "fun" sounding headphone are unmatched.

If you like boomy sub bass then I would look elsewhere than the Fostex series. They do bass with amazing control, the first time I put my TH-900's on I smiled because of how punchy and detailed the bass was. The Denon's... in comparison are more boomy with less control. I would say they suit a bass head's needs a lot better, and they are cheaper as well. Out of the four choices you have there, I would choose either a D5K, or D7K over any of the other choices.
