Dolby Atmos vs DTS:X
Dolby Atmos and DTS:X gives sound a three-dimensional effect. Just think of hearing a far off a jet flying from a distance away then passing directly over your head.
So how do you get Dolby Atmos and DTS:X 3D sound in your home. Well you can buy a Dolby Atmos and DTS:X sound bar with front and upward firing speakers all setup to go like the Samsung HW-K950/ZA 5.1.4 Channel Soundbar with Dolby Atmos Technology or buy a system like the Onkyo TX-NR656 7.2 Channel Network A/V Receiver.
The 2nd option of buying the Onkyo TX-NR656 7.2 Channel Network A/V Receiver is the DYI approch if you don't intend to get an installer to set it up for you. There is much more work involve when doing this, wiring up the speakers and configuring the system.
