Clean, Crisp, 2nd pair of cans. ~$150

I haven't hear them personally but the Fostex T50RP is suppose to be really good for the price and can be found for $129 on amazon.  I can't speak to the K701s but but have heard the Q701s and they sound really good, especially for the money and sound like they would fit what you are looking for and are suppose to sound like the K701s but with a few extras like a removable cable.  The Alessandro MS1i are the same headphone as Grados so if you don't like there sound then you won't like the MS1i either.

Forgot to mention that the T50RPs can be modded to so to improve the bass further which might suit your music style.

I have the M50s and the Grado SR225is, and I don't know what that "harsh 'rock' type of sound" means. I was initially hesitant to try the Grados because of those types of negative comments, only to find that I really like them and those kind of comments didn't make a lot of sense. They are definitely brighter than the M50s with more better mids, with a wonderful sound. Great clarity and much better soundstage than the M50s. 

Still, their signature sound--like any other headphone at head-fi (some people feel the M50s suck, but I think they are good for what they are)--may not be for everyone. 

I've had the MS1 for about a year now, and I love them. I tried the Grados and the 225 was the only thing i liked, the rest of the line had the sound I was looking for but just a bit too bright. I ordered the MS1 for giggles thinking that they have a high resale, so what the hell? I was really surprised. I had an HD25 set at the time, and although the MS1 lacked the last 10% of detail the HD25 had, I preferred the more laid back, but still crisp signature of the MS1 and sold the HD25.  And to boot the MS1 is very nice to vinyl or vinyl rips. 

They are at the brighter end of the spectrum than some other headphones I have heard, although the treble is not harsh and fatiguing to me like my Ultrasone HFI-780s can be (and the 580s, which I have demoed). They are described as good for rock because they have a fast transient response. They can really nail the accuracy of the response. 

They are not usually recommended for EDM because they are not bass heavy phones and don't produce much low level bass (they roll off a lot by then). But I find that they have good mid-bass. It's just not accentuated--the mids and highs stand out more. So I can listen to Girl Talk's All Day album and be satisfied if I'm not in a bass heavy mood (I have the 780s for that or my M50s). It's really going to depend on your personal taste. 

Maybe you will love K550 but sadly it's out of budget. T50RP is a good choice too, clean grainless sound since it's an ortho

I'd recommend the Shure SRH840's.  Very neutral headphones with great detail.  I especially enjoyed the midrange (best part of the headphone in my opinion) though the bass impact could be lacking.  This may or may not be ideal for listening to electronica but I also listen to a lot of the genre and I felt the attack/decay of the bass was crisp and fit in with the music.  Definitely handles fast music very well but if you're looking for more bass impact, then look elsewhere.
