Headphoneus Supremus
I don't have any personal experience with any of the headphones you listed in the first post except the HD419. I found it quite boring to listen to and gave it away. As far as other headphones that have been suggested, the 681 Evo is becoming pretty popular and should suit your needs fairly well. As far as the Atlas is concerned, its rather new, so not that many people have given it a real try. I'd suggest giving the JVC S500 a look as well.
