Sonos arc vs Sonos amp and floor speakers.

Hey all, just curious if anyone had compared the sound between the two? I don’t have a lot of space to afford a 5.1 setup in my house so my options are quite limited.

Lately I’ve been disappointed in the dialogue audio of my arc and have thought about using my amp and floor speakers for my TV audio and music streaming. I also have a GEN4 sub for either system.

Has anyone tried just an amp and speaker setup and if so how did it compare?
