We have similar tastes, and also have a collection of phones I use for production
There is nothing wrong with a fun headphone to relax.
The d2000 tyou may want to listen to first, because I have read way too many people complain about muddy bottom end, and if you like IDM, and allit's subgenres, as well as dubstep, especially dub, because bassline is insanely important with dubstep, or any dub, and I know a lot of IDM with sub-bass youy just don't otherwise hear. I would rather that roll off than to be muddy. TThe D2000s can be modded though, with dynamat, but again, there are easier ways to get a kick back and nod your head phone.
I would look for the Sennheiser HD595, or better yet, the 555, that takes all of 20 minutes and basically no problems to bring them beyond the stock 595. It is a headphone that gives you a lot for the money, especially now since the 558 is coming, which can also be modded in the same exact way heh.
The driver in the 555 can move a ton of air and I used to use it exclusively for my personal listening when it came to electronic music, and I even produced a couple tracks with them. Easy to drive as welI would be careful of the k272/271 or k242/240 whatever the latest ones have been from AKG because, if you are ever going to plug them into a mixer or console, they will sound like garbage. (a certain opamp is used that puts out a lot of current at the expense of fidelity that most manufacturers love because it can drive many headphones.)
I had to spend a long time finding a good setting on the parametric EQ for my k271s, even then, my NAD preamp in the other room was magical with them, but the 240 seems hard to justify at all. Not sure about the MKII versions, but I know the versions right before were very dependant on synergy.
Look into Ultrasone... They make some nice headphones that are called monitors, but that brings me to the next idea, a Beyer DT770/80 with 880/990 pads is just amazing. I use my pair just to listen to music all the time. The 880, as well, is very good with the complex textures of electronic artists. The Shure 440s are said to be studio monitors, and they feel like it, look like it, but damn, after they break in, they offer some of the best sound from one end of the spectrum to the next, depending on tastes, the m50 rom AudioTechnica is either better or worse than the 440. The m50 certainly won't dissappoint. As purely a fun audiophile headphone, they fit in very well... Ultrasone is like that since so many of their phones look like monitors, and many people overlook the old DT770pro/80, but it delivers.
Sony has a couple headphones out that can be had new or used, that would sound great as a guilty pleasure can. One in the stores is the XB700, and the cx900 model can be found easily. Just buy extra pads for it... heh.
If I had to pick one headphone on my wall, where I have them on hangers I made, I would pick a Beyer or a Sennheiser HD555/595, or the 558 if it comes out soon, as it is the giant killer of the senn. refresh, and it is just as east, even easier, to get right up close to the HD600, but more fun. It has a driver with a huge dome, and it does respond to whqt you throw at it, but it isn't fatiguing. IT is covered in velour, and it is about 100 dollars or less. I bought mine when they came to a dealer here for 3 bills, now some get them for 90 dollars. The mod is so simple, you don't need to even bother with the wire mesh or the honeycomb, just rip the clot out from under the grille and pull off the rubber tape behind the drivers. Add some blue-taqc for some mass loading and wow... there are Autechre tracks that to this day, I cannot listen to on anything else, especially the first song off one of their later albums, "confield".
Also, I would truly and honestly recommend this with the left over cash from buying something like a dt770pro/80, or a senn HD595/555, even a Shure 440, since so far, they only seem to do electronic well, and other genres cause migrains. The 440s seem designed for the sound of production and DJ culture.

The original B-283 can sound sweeter than the new one... and it is so inexpensive to add such a wonderful tube warmth to anything you plug it into... Take the analytical output of a mixer or a production/reference system, and place this after it and then wire this into your headphone amp, or just some isolated patch, something, anyay, the organic quality it adds is great. I have not bought the MKII because the previous biffers from GF and Yaqin, they used the tubes... the old Yaqin using a triode, so two channels in a single tube, and the B-283, two pentodes, only one signal can be run through a single one, so to have two, obviously... but the MKII uses a more powerful preamp tube, but without gain, of course, just with all I know about the b-283 original, the 6J1 model, it is a steal, and just grab some RCA 5654/6ak5 black plate tubes, even the ones from the 70s that I see on ebay all the time, and it sounds *good*. SO good, that I worry less about if a headphone is for monitoring, I only care about fidelity and synergy with my setup, as well as the bedroom studio. I have only ever had problems with a cheap pair of sony walkman phones that I composed a song for, that played awefully on the speakers... the best music I made, I made using the Senn HD555. It, and not it's new version, the 558, I can say for sure the HD555 is one neutral reliable piece of gear that will LAST. YOU also get to save an extra 100 dollars by spending 10 minutes to do the mods.
i listen to a lot more intrumental post rock, prog rock, fusion, jazz, etc, even some that blurs the lines between what is electronic music? (Zoe Keating anyone?), but while I own a lot more headphones, the senns still have to be one of my most fun pairs. It is just easy to get into the music and atmosphere.
