There are actually some streaming services offering atmos and high-res audio, so the market is actually quite interesting right now if you have the budget for the equipment. A top of the line experience will cost you a bit north of $1000 per channel assuming you dont get too picky with the speakers, do would be 7+2 -> 9K for a full blown domestic system. The audiophile crowd is buying 2 channel dac systems at a third of that value, just because.
