D1100 are discontinued, but they were originally like $150-$200. PRO700 I have no idea on SRP, but they're around $175 on Amazon (in the US) right now. The Anniversary version might've been $300, I don't know what the differences are beyond the appearance. But neither of them should be $300-$400 cans.
As far as the lots of bass comment, I'd agree and disagree. Quantity doesn't have to mean a lack of quality, for example the Kenwood KH-K1000 have EXCELLENT bass quality, *and* can hit fairly hard. The Ultrasone models I have (or have had - I tend not to have closed-back headphones though, so I'm talking about their various open models moreso) have excellent quality and *lots* of slam when needed, it's the entire package. But then there's cans like the M50 that have lots of impact, and can get a little ham-handed and boomy by comparison.
If you don't need a closed-back headphone, I can honestly suggest either of the "top" Ultrasone open-back models, the HFI-2400 or PRO2900 (the 2900 is the better of the two, basically it takes everything the 2400 does and improves upon it, but it also costs more (about twice more)).
