All of the above, though I don't quite know what you mean by depth.
I'll just say that I think the L3000 sounds like a dynamic Omega 2 (so you'd more than likely prefer the O2), both have exceptional imaging, and are a tad soft in the highs. The Omega 2 probably has better (or different?) decay, both have very fast attack.
The biggest difference being the Omega 2 has more depth to the soundstage, which I do miss with the L3000. But I have the K1000 when I really want that experience (or hopefully some speakers soon!11).
