Anyways, it looks like God doesn't want me to own a 900, so I bow to fate. In order to have something ultra-bassy to compare the 1540 to I went to Fry's and picked up a JVC HA-MR77X.
OK, so what about the Shure? It's stunningly beautiful, all carbon-fiber and aluminum and it barely weighs anything. The comfort is unreal. Is it a bass cannon? No, but it is bass-tuned, and a bit bright as well in the upper frequencies, which I enjoy. I could boost bass a bit beyond the point I can with my DT770s but not much. However, the SQ is simply retarded. Level of detail, transparency, and overall goodness is mind-boggling, it curbstomps my DT770, and that's a fantastic headphone in its own right. (It also curbstomps the V-Moda M100 I demoed.) It handles all genres pretty much with equal levels of awesomeness.
What about compared to the JVC hammer? OK, well, the JVC weighs about 3 times more. It's all plastic, but tough plastic, built like a tank. You could literally kill zombies with this thing. Certainly far less comfortable to wear than most anything else I've tried, though. The earcups don't even seal completely so I imagine leakage is not so good. What about bass? Yeah, it's got bass, more than the 1540 for sure, but actually not as much as I expected. I'd say it can output about 35% more before obvious distortion immediately kicks in. (The 1540, interestingly enough, did not distort as I raised gain on a bass tone, but stopped increasing in volume past a certain point, which I took as a sign to back off). But SQ doesn't even compare to the (very nice) Sony MDRX10 I currently use as a portable.
So the JVC is going back tomorrow, SQ is not even good enough for use as rap-only cans. The 1540s are absolute keepers, there is no way SQ gets better than this for less than a grand. Bass output is good enough for EDM (and of course rock, pop, etc.) but not all that I want for rap. However, only about 20% of my listening time is spent on rap. The Ultrasone 900 might have more bass but seems very unlikely to approach this in overall SQ... assuming I could even acquire a 900, which seems not to be in the cards. The Signature DJ might be all that, but I'm not buying two pairs of $1000 headphones, especially not white ones that will turn beige over time, as I've read.
