Looking for some recommendations / opinions on my next headphone purchase. I currently own MDR-7506, MDR-1R, K545, and Fidelio X1's (and some custom molded UE Pro IEM's). Looking to take the next step up but not quite into the realm of "summit-fi" headphones, more like the level before Summit-Fi, in the price range of $400-800.
I primarily listen to rock music, both classic, modern, indie, etc. Also some electronic but not like dubstep or anything like that, more like electronic rock. I own a few closed-back and only one open, so I'm definitely fine getting an open-back, as it seems like most of the highest rated headphones in this range are in that category anyhow.
After a lot of reading & research, I'm mostly considering the HD-600, HD650, HE-400, HE-500, or Fostex TH 600. I also am really lusting after the Shure SRH 1540's, but I don't know if they can really compete with the others in terms of sound quality… Seems like the verdict is still kinda out on those, maybe cause they're newer. I also am very keen to experience the Sennheiser sound, since I don't own any and they are so highly praised around here. Although, as much as Senn's are loved, it seems like the HE-500 are actually more praised for their sound quality sometimes. What do you guys think? Are there any other ones that I'm overlooking?
EDIT: I forgot to mention - I am looking for something that is, ideally, a significant step-up or at least a CHANGE from the X1's. Those are pretty awesome and I think some compare them in overall quality to the HD 600 & HD 650's. I just don't want to get something that is pretty close to what I already have - I'm hoping to make a significant step here. If I can't do that at this price range, than I may opt to wait and save up to a 'summit-fi' model, which would probably be the K812. I'm constantly lusting for those.
