With the Denon AVR-X6300H ($2200) AVR, AV enthusiasts can power an entire 7.1.4 Dolby Atmos or DTS:X immersive audio speaker system without the need for an external amplifier. While past AV receivers from the company have offered 11-channel processing, this is the first product to provide 11-channel amplification built-in.
Specifically, the AVR-X6300H offers power output rated at 140 watts into two channels, with an 8-ohm load, from 20 Hz to 20 kHz, with 0.05% THD. At with a 6-ohm load, Denon's specs are 175 watts into two channel, with 0.75% THD.

It's no surprise that a top-tier Denon sounds great, or that Dolby Atmos provides a compelling listening experience. The show demo delivered as it has in years past. Watching The Last Witch Hunter, as well as some shorts from Dolby's 2016 demo disc, everything worked as it should, with precise placement of sounds. The novel thing about it, as compared to demos of years past, was that the entire 7.1.4 experience was powered by the AVR alone.
The company also showed its AVR-X4300H ($1500) AVR, which does offer 7.1.4 processing, but only comes with nine amplifiers. You also give up a little bit of power per channel versus the higher-spec'd AVR-X6300H (125 watts into two 8-ohm channels with 0.05% THD, instead of 140 watts) but overall you get a lot of the same features in a very attractively-priced AVR. Add a powerful external amp for the front L/R speakers and you're in business.
Networked, lifestyle audio products represented the most obvious, inexorable trend at CEDIA 2016, where Denon had lots to show including a broad array of HEOS multi-room, wireless, networked products. The aforementioned new AVRS include HEOS capability, and then was an enigmatic box spotted on the show floor at CEDIA that Denon literally calls the HEOS AVR.

The HEOS AVRs modern, minimalist chassis was completely free of buttons, dials, or displays—except for a large volume knob. All of the audio and musical magic occurs inside the aluminum chassis, which contains five channels of class-D amplification (60 watts per channel into 8 ohms). What sets it apart from your typical 5.1 AVR is that it can use any HEOS speaker as a wireless surround in a 5.1 system.
