That's a neat trick. In addition to trying that I looked into some more posts about EQ-ing. After some playing around (and separating the chords from the melody) I concluded that the piano lead is just a bit boring in and of itself. I then played around with some synths to give it more of an actual trance sound, but that soon forced me to almost rewrite the entire piece from that part on. I tried a number of different things, but in the end I can't get to a satisfying result. I've already spend way more time than I intended to spend on this, so I think I'll let it rest for the moment. Maybe I'll come back to it after a while when I've learned more things or found better samples/sounds/VSTs to use.
Nowadays small details of response comparison between studio monitors are moot and needless effort to shop around for. If you pick up Sonarworks Reference 4 w/ their mic, then once you set up your monitors in the right configuration, calibrate the Reference 4 profile. The mic will detect differences between expected signal sound and what both your monitors and room are giving you, and apply a counter filter that cancels the differences out. You do have to manually set it to linear phase, which adds some latency to your path, but having that un-affected phase response is crucial.
It gets you way better results than agonizing over configuration settings. The important thing is that you just buy a good quality set with a decent response and then have your room at least minimally treated so that Reference doesn't have to do an unnatural amount of work to fix it.
Reference mostly gets a ton of praise all around, but also a small handful of disappointed customers, so you can shop around for other companies that do the same thing, there are multiple ones.
That being said, your mileage may vary if you're throwing a subwoofer in there too, since it needs to calculate L/R independently. Honestly like... a subwoofer isn't necessary, and I see of accomplished (home) engineers leaving it out of their setups. Getting something above 5" drivers for your monitors will already guarantee you a good sounding bass response.
Getting a sub can actually be detrimental if your room isn't right for it, or you aren't prepared to potentially do a lot of interior design work to make it work.
