Just moved, new space, lots of years since my last move or gear update, a little bit of money saved up, time for some new gear. I've got a 75" Samsung Q8, and I'm looking at SVS Prime Pinnacle Surround system plus one of their subs for the speakers. But I don't have the space (300 square feet of loft) to go more than 5.1. I don't want to spend more than $2k or so, but I want the most I get can get visually and audio-quality wise. An 11+ channel system seems a waste, but is it the only way to get the quality and the beef and the technology? I'm completely brand agnostic. What do you all suggest?
