well, i still haven't voted. and i'm a Team Beyer & AKG member... That being said, I'm surprised that you didn't have ATH on your short list. I would think that you want a forward sounding headphone with comfort. That would lean towards the HD590 and ATH900 (US$200 range), from what I've read. I own the K501 and do not feel that it may do justice to your types of music, being just slightly dark, though they are very comfortable. I, personally, do not like the eggo fit of the eggo HD590s, and I don't know what the pads are like on the ATH A900.
you haven't said what type of mids and highs you like.
when is your next vacation, and are you going abroad? it may provide an opportunity to audition headphones. isn't there other head-fi members in Sweden?
Perhaps if you put up Swedish franc prices, we'd get a better idea of the comparative "worth" of the above headphones. what does a SR80 go for in Sweden? (SR80 go for about US$100).
