Denon AVR-X6200W

When you have nine separate 205W amplifiers on board, like this bad boy from Denon, driving a 7.1.2 Dolby Atmos set-up in a large room is a breeze. Denon’s clever processing actually lets you stretch to a 7.1.4 arrangement if you add your own stereo amplifier and additional height speakers. Eight HDMI inputs handle your tricky HDR and 3D sources, outputting everything in glorious 4K.
