This is what I have in my living room setup that isn't too costly, as far as audio systems go, and sounds great!
Older offering from klipsch that still sounds great and can be found pre owned at a good price. Speakers are powered so seperate amplifier is not necessary and also comes with remote!
Klipsch R-15PM Powered Monitors
A solid DAC that makes everything sound better. Comes with bluetooth as well! (If you don't need bluetooth look up the cheaper smsl su-1 instead) Connected to TV with an optical cable and to the klipsch speakers with an RCA cable.
SMSL DO100 PRO HiFi Balanced DAC
Subwoofer that can be hardwired or setup wirelessly with a seperate bluetooth device.
Klipsch R-120SW Subwoofer
This device connects the subwoofer and speakers if you don't end up getting a wireless subwoofer as well!
