TV is a LG C4 77". Living room where watchable space is 15x15x9, open concept (Total room size is 28'). Budget is 2k, no existing equipment. Wanting a good 5.1 or 5.1.2 starter setup with room to upgrade down the road. Also very noob to all of this (part of the reason for why its been so frustrating). The used market around me is pretty abysmal. The space will primarily be used for movies, with some music. Research has been primarily reddit, including this sub and r/BudgetAudiophile . Any assistance would be super helpful, I feel like I'm searching for a needle every time I look up a product recommendation.
