I'm still definitely interested on headphones! It's just I need more time with my Harmony and the audio cable. Would like to do back-to-back comparisons before I see if my headphones are close to audio cable in sound quality otherwise I'd look out for the ones you listed. 
I'm really digging those HD595 in the way it looks and the reviews on it, but open headphones mean someone close to me would hear it too and get annoyed, so... 
Think there's a closed one that also looks like the HD595 in design? is the cans really big? It looks perfect on Amazon which reminds me not to believe what you're seeing in the pictures on the internet because it might look really bad in reality!
EDIT: Hey look at "rigs" in this thread: http://www.head-fi.org/forum/thread/397869/pictures-of-your-computer-rigs-post-them-here
Looks like I'm missing out on something here... fancy stuff. :P
