Looking for a step up from ATH-AD700's

[Lukan]

I've had them for a couple of years now, and they're starting to decay (mostly those top things that go on your head. I had to cover them in duct-tape, because the plastic-holding bit broke off, and was jamming into my head), so I was looking to upgrade.
 
I'd be using them mostly at my computer with an FiiO E7, and maybe sometimes on a Sansa Clip+ with an FiiO E7 (probably not a lot, though). 
 
I listen to all sorts of music, so I'd rather they be good for all kinds, rather than tailored for metal/jazz/rock/rap/whatever. 
 
Not really sure about my price range. I am wary of spending a lot on headphones, so I'd like it to be somewhere around 200$, but at the same time, I really do want it to be a step up from my current pair. I guess I'm looking for the lowest-priced pair that will still give me a nice audible (almost typed visible) improvement.
 
Other than that stuff, I'm not sure what else I should put, so please ask questions if I've left anything out.
 
EDIT: Oh, also, I'll probably be going to sleep soon, so I won't be able to reply to anything until I wake up. Maybe making a thread right before going to sleep isn't the best idea. Oh, well.

DT440 or DT250 (if you want to try closed).  They are better overall but the more natural balanced sound signature is what you will probably notice 1st.  Both have better detail, clarity, separation and a more focused soundstage (though smaller). Bass response is noticeably superior, as is the midrange (not as colored/recessed/unnatural sounding).  Treble isn't as prominent so that could be a good or bad thing depending on taste. I found the AD700 a bit too sparkly sounding.  I guess it really depends on what your looking for. If you want a better sounding AD700 you'll have to stretch your budget to the AD900 which improves on the bass and midrange problems of the AD700 while keeping the same general sound.

Cool. I looked at some opinions on the 250 (I think I'd prefer closed to open, but I'm not really sure. I've never tried a closed one. What's the difference?), and it looks pretty good. Unless something else comes along, it's my current buy (I won't be buying these immediately, though. So something could come along). 
 
I don't necessarily want to get a better version of the AD700. I just want something better than the AD700.

I just wanted to make sure, so before this sinks into the abyss, I'm bumping it one time.
 
Does anyone have any thoughts on the DT440, DT250, or really just my post in general? 

 

[Trysaeder]

The DT440 sounds good. Have you looked at the AD900 or is that not available near you for a reasonable price?

 

[Lukan]

I haven't, actually. I sort of would shy away from them, because I don't like those head-pad things (the things that the 700 also has). 
 
I'm not really sure what places have headphones around me, so I usually just buy from Amazon. Are there stores to look out for that might be around me?

 

[Trysaeder]

I'm not sure, I just thought that the US didn't have AD900s.
 
After the entry level, most phones will require amplification, so the leap to mid-fi is pretty hard on the wallet. I faced the same problem and went straight for the MS-Pros, which you will probably not be doing.

 

[Lukan]

Oh, yes, I see. 
 
Well, I do already have the E7, so I thought that would take care of the amplification. I do plan to, at some point in the future, pick up the E9, since I've heard a bunch of good things about it. 
Yeah, I will probably not be picking up the MS-Pros.
 
Does anyone have thoughts specifically on the DT250? I think that I might like that better than the DT440, but it doesn't look like a lot of people have written about it.
