Dolby Atmos' particularity is that this is the object-oriented sound format, that is, each audio signal object is independently sounded and connected to its spatial position. Marantz SR7015 can create 3D sound due to the Dolby Atmos support.
DTS:X is an algorithm used by the processor to create sound scenes, where sounds connected directly to objects rather than channels, and to determine the optimum sound output distribution in space. Surround sound with DTS:X is available on the SR7015.
Auro 3D gives a bit more versatility than Dolby Atmos or DTS:X and provides a hemispherical sound and enables a receiver to produce 3D sound stages. Marantz SR7015 has Auro-3D on its feature list.
IMAX Enhanced is a licensing and certification program under which home theater devices deliver crisp 4K HDR pictures and powerful sound as it was designed by the IMAX engineers. The SR7015 licensed by IMAX.
