Heya,
Money is an issue. You can get $3~4k setup recommendations all day.
But that doesn't mean it's worth it. Spending tons of money for equipment for anything in audio better reflect the quality of your music. If your music collection is a bunch of variable bitrate MP3, or youtube rips, or something other than high quality lossless or near-lossless or straight-from-source, then going to summit-fi level equipment is simply not going to net you anything other than a receipt and less money and a little internet bragging right since no one in real life will have a clue what any of it is, or what any of it represents.
Feeding a nice headphone setup a bunch of compressed tracks is garbage in, garbage out. A good setup will not make something sound better. The original source, the music, has to be flawless. Even a lossless recording is not just enough--the recording itself has to have been done very well too. There's a lot of albums out there that are simply mastered poorly, full of noise, hiss, grain, where they used cheap microphones, or had a really junk studio to work in, or who knows what. But not all albums are equal just because you have them in lossless format or the original. Electronic in general is produced without microphones and other common sources of noise/low quality. So you may be ok there. But when it comes to electronic, I know tons of people are getting their electro off-line from streamed content websites, youtube rips, iTunes purchases, etc. You really have to go after the highest quality you can here. I just can't stress it enough. Even a mid-level headphone setup is going to sound way better with absolutely high quality music. Focus on this rather than getting the "best" equipment and you'll have a way better experience.
I would instead recommend a sensible path for you to begin with, until you are confident that your music library's quality is worth a $3k setup or not.
