I think it may be matter of one's own sensitivity. I think I am somewhat sensitive to it. I love the sound of the W5000s, there is some serious WOW factor going on particularly for jazz & vocals. If that is what I mainly listened to and the brightness wasnt a problem, I would stick with these cans. I dont listen to jazz & vocals too often and the brightness can be uncomfortable. For you, it might not be a problem. I have not once felt that they Denons are too bright.
As for the bass, the W5000 has a beautitful, rich, textured bass. I think it really sounds incredible as long as you are not listening to music that emphasizes bass, such as my favorite, funk. Again, for jazz and vocals, the W5000 are the way to go if the brightness and comfort are not a problem.
The best thing you can do is find a place where you can A/B them with several of your favorite CDs. Still, until you get them home and spend a lot of time with them, it is hard to tell.
I think you are safer with the Denons. Just keep them in good condition so you can sell them later if they turn out to be less than you hoped for.
