I've read some really positive reviews on the XB700 and some like them more than the XB1000's.
I think most people go through a period where the sound signatures they like change. For me I used to like a more V shaped signature until I heard a good mid-forward pair and now I like the more mid-forward to balanced sound. The one HP I have that can be called V shaped is the HE-400 but they don't sound as V shaped as their frequency graph shows imo. I'm also liking a little more bass in my music than I used to but not much so a little EQ'ing works great though my Colofly C3 doesn't have one and my amp has no boost but the C3 starts off with good bass so I can deal with that.
