I have an amp that supports Atmos and DTS:X. Speakers can either be 7.1 or 5.1.2. So it's already set as 7.1 but I could add ceiling speakers and connect/disconnect them with banana plugs when I want to switch 7.1 to 5.1.2 or vice versa. So is it worth it ? I mostly play PC games and I'll be watching Game of Thrones so I suppose the Dragons will sound cool I noticed season 7 uses Atmos. I had some upfiring Onkyo speakers when I bought the amp but I sold them, if I go for Atmos/DTS:X should I get upfiring or ceiling mounted ? And how much would I have to spend to get some good ones ? Also need some brackets if they're ceiling mounted. Thanks.
