Whew, I just replaced about 5 albums that had files floating around 200 Kbps and it was not fun. Much more to do. Anyway, I won't quote because of the length of the posts, so a few things: I like the fact of clean audio and if the bass is better than skullcandy's aviators (if you had the misfortune to listen to them), then the psb should be good. What you were trying to describe with the soundstage sounds exactly like what I love. A wide soundstage is great, but more importantly, I want to be immersed. I've rarely experienced that. IMO, RATMs songs don't quite have the complexity for good testing. Could you give me some songs that the psb do great with? I'll give you this to test: the who eminence front. Very complex with intricate little sounds. It sounds good in my se215s, but the tiny drivers sometimes struggle when the vocals come in. Another thing is that most of the time I'll listen to headphones unamped. Of course amps are helpful, but I'd prefer an efficient headphone whenever possible. About the hp100, mids are important to me, they're apparently a bit v shaped. I'll probably add another post after I Re-read stuff, but after all of that file management and replacing, I need a break.
