Help me with my PC setup please.

Hey, so. I don't know much. I somehow came up with that set up due to multiple sources, but I am not sure if it's really smarter to split my budget into 3 different pieces, instead of 1 very expensive. My budget is around a 1000 bucks. A little more is okay, but not by much.

What i bought:

Speaker: KEF Q350 ( 400€ )

Subwoofer: Canton Sub 300 ( 400€ )

DAC: Loxjie A40 ( 180€)

I think I should mention that it's not important that they are able to be very loud, since I definitely need to play without bothering my friend I share an apartment with to much. So, I want clean and immersive sound on a ordinary volume.

Being able to upgrade later would be nice, but I don't wanna stress out too much about it. I can sell and upgrade anyway. I'D lose some, but I don't think enough to really stress about it.

Thanks guys!
