These two headphones are world apart; I'll refer you to measurements:

I'll also tell you that you cannot make headphone A into headphone B with an EQ - you're acting on one of about a hundred variables that you'd need to change to produce the results you're after.
I would also not consider the Beats Studio a "benchmark" for audio quality (there's a few reasons for this, the biggest being the ANC circuitry and what I suspect to be a high-Q design that gives them their signature "boomy bass").
Now lets break up some other mythology:
- There is no objective or logical criteria for something to be "audiophile grade" - it's a pure marketing fabrication, and it's easiest if we just dispense with it. You can waste a lot of money trying to get to "audiophile grade."
- Don't even start worrying about opamps, DtoAs, etc - it's a big hole that you can put a lot of money into for not a whole lot of reason. If you have a bone to pick with me about this, don't go down that road unless you've also got numbers to go with it.
To what you want:
You mentioned liking the Beats Studio, because of the bass. Well, there's quite a few options that can get you bass. However, none of those options will get you "recording flaws" (why on EARTH would you want to listen to that?) - for that, we need to take a trip over to the studio monitor department. You then get to make a choice: bassy and "fun" or flat and "accurate" - you don't get both (because they're opposed to one another). I'd very seriously re-assess your music library before you take a jump here; if most of your music is in that 64k-192k range that seemed so appealing ten years ago, I would *highly* suggest you avoid the "flat and accurate" camp unless you enjoy the sound of compression artefacts.
Very broadly, and yes I realize I'm making a lot of suppositions about what you want and what you're trying to accomplish (but just go with it, okay?), give the Ultrasone HFI-2400 a shot; they're around $200 on Amazon when they go on sale (which is frequent), and will gladly run from various "headphone amp" soundcards, as well as other devices properly equipped to drive headphones (lots of A/V equipment, headphone amplifiers, etc). The Denon AH-D2000 (which are not $200) are not a bad choice, my complaints with them relate to build quality above anything else - they're simply not put together as well as a $300 product should be (then again, neither are the Beats). If you're very gentle with equipment, the D2000 are not a bad choice, although I do find the treble quality a bit harsh; they are very much a "happy v-curve" though.
I wouldn't suggest getting too wrapped up in reading about everything you can possibly find; you'll probably go mad. Pick something and try it out, if it doesn't work, try something else. You'll at least have a better frame of reference with respect to what doesn't work for you, which will let people make more realistic suggestions that aren't built on a straw-man.

is the Audio Technica ATH-AD700 Open-air Dynamic Audiophile Headphones as good as the beats studio with a little extra bass "bump" in anequalizer
