How to choose acoustics for a computer?

Question

Sound cards

I understand that it sounds ridiculous, but what can you take for an initial entry into the territory of sound? I listen to electronics and classical music, a lot of movies. It’s just that I now have ridiculous Swen, which I bought 7 years ago for 1600 rubles, so you understand ... I recently bought Audio-Technika m40x headphones and I wanted to take speakers as well. A friend also advised a sound card, for example asus xonar phoebus or creative sound blaster z (which one is better for electric music and cinema?)
I end up thinking between edifier r2700, microlab solo 6c, sven royal 2r and the like ... I
listened to microlab solo 6c, I liked them, but they jumped in price in a few months and I think that they can’t cost 14k by any means (a friend recently took it from his hands for 4k in excellent condition).
