The W5000 are a pretty bright can overall, which some of the weaker bass I've heard. I have heard them even with the headband adjusted for more bass and felt the bass was still very weak compared to many other headphones like the HD600, W1000X etc. They have a very impressive soundstage for a closed can, but I feel that they have a nasal/honky tonality, some find this sound to be a magical one. For the sake of your wallet these are a headphone that is controversial a fair bit of the time, unless you know you like the AT mids steer away. The W1000X would be the safer bet if you went that direction, as they are warmer and more balanced in the low end as well as less nasal.
The D5000 are a can with strong bass, and prominent treble. They can be a bit rough around the edges at times, the mids are not very forward but are not strongly receded. I would pick them over the W5000 personally.
The Alpha Dog and the ZMF x Vibro are ones you should definitely consider as I feel that they generally are better than the above mentioned headphones. The difference between the two is that the Alpha Dog are brighter and have less bass, while the ZMF is bassier and darker. The Shure 1540 are not out of reason either, being a warmer can too.
Best to read some reviews of the Alpha Dog and other closed cans before you venture too far into making a purchase.
Of course with any impression YMMV, so always take peoples opinions with a grain of salt as they may not hear things like you.
