Keep Swan D1080MKIIs or replace with used Polk S15s?

I'm pretty new to bookshelf speakers and I'm wondering if I should return my Swan D1080MKIIs($190 on Amazon) for cheaper used Polk S15s (~$150 on Ebay). I've had the D1080MKII for a few weeks and I enjoy them but I'm wondering if I can get a better setup with the money I spent on those speakers. I would need an amp for these Polk S15s as I do not currently have one. My budget for the speakers and amp would be about $300 after returning the D1080s.

Currently my setup is like this

Turntable -> Phono Preamp -> Schiit Sys Input Switch with TV -> Swan D1080MKII

The Schiit SYS and the D1080MKII are still in the return period. The return period for the D1080 is until July 2nd. This is for a somewhat small living room space in an apartment.

Is it worth replacing the D1080s or should I just stick with what I have? I'd like to get the Polk S15s as they look like better speakers and I'd be able to plug them into a receiver without having to find one with pre outs for active speakers. I'd be able to consolidate some of my current setup.

On the other hand, my setup right now is fine. I could just be feeling FOMO about the Polk S15s. I'd like to get a receiver at some point so I can have a remote for my speakers though

If I did buy an amp for the Polk S15, what would a good budget receiver be? I've looked through a lot of guides online but prices right now are pretty crazy and there's a lot of outdated information.
