I've had the ATH-A700 for some years now, and as much as i love their smooth and spacious sound, I want something with a bit more speed and impact, as in tighter and more controlled bass. At the same time, I don't want to loose out on too many of the A700's strong points. As much as i want more quantity in the bass department, there is nothing i loathe more than sloppy, slow and muddy bass. It has to kick me in the face, not slowly push me over. I was originally looking for open over-ear headphones, but I am open to closed phone suggestions as well. I have a uDac2 in the mail, and will be using the phones exclusively at home (looks and sound leakage do not matter, and I have different gear for the gym and for traveling). Budget: within reason :)
How about a Grado? While generally considered bass light, they've got about the same quantity as the A700 but tons more kick to it. You can start off with a cheap SR60, or move up into the 4 digit range if you're so inclined. Grados also have plenty of mods available to them, to tailor the sound to your liking.
