In regards to your question about bass thump: Though I love a deep and slightly elevated bass presence, a lot of the music I listen to has rolling bass lines that reach DEEP. But... I do have this trance CD that I'll put on occasionally and bop my head to till I have a headache.
So I queued up my fav song from that CD and A/B'ed the Denons and Atrios. The Atrios actually give you a bit more of the thump you are looking for but both of them probably would disappoint you. I have a theory why that is. This is total conjecture, folks, so if I'm way off go ahead and tell me I'm nuts.
I think that thump you're looking for is actually a bit of bass distortion from either ear/headphones or speakers that can't handle the driving bass beat. That or the drivers are handling that specific frequency in a way that accentuates it.
Both the Atrios and Denons reach impressively low and soften that hit you are looking for. These are both very musical, easy-sounding earphones and because of that, lack a bit of speed. I also queued up a Venetian Snares song with the C700s in and a bit of the razor edge of the rapid fire drum beats and high treble electronic cymbal crashes has been dulled.
So if that kick drum hit is really critical to you - I think you might need to look elsewhere. Sorry.
