While debates on whether or not to need 8K, the new line of Denon receivers are ready for higher resolution video when and if you decide to upgrade. Perhaps more importantly, they also support HDMI 2.1, including features such as automatic low latency mode (ALLM), variable refresh rate (VRR), 4K video throughput at up to 120 frames per second, and fast frame transport (QFT) that reduces input latency. These features are especially important if you plan to get the Xbox Series X or PlayStation 5 when those consoles ship this fall.
All four new X-series receivers include one 8K input and they support fast media switching (QMS), eliminating the need for blank screens when switching between content that uses different refresh rates. They also support Roon music management that brings in metadata for your various media files, and voice control with Amazon Alexa, Google Assistant, Siri, and Josh.ai. To set up your sound, Denon has a Setup Assistant app while Audyssey MultEQ software handles automatic room calibration.
The three high-end models now include a pre-amplifier mode that turns off the internal amplifiers and provides a clear signal path for your audio – useful for people who have speakers powered by external amplifiers, and a feature previously limited to the flagship model only. A new feature builds in a Bluetooth transmitter so it can route any audio directly to headphones or hearing aids, whether you have the speakers on or not.
An important difference between the four models is the amount of output power and channels supported, but the flagship AVR-X6700H is the only one to get DTS:X Pro support with up to 13 channels of decoding for your 7.2.6 or 9.2.4 speaker configurations as soon as it receives a software update later this year. The rest will have to do with Dolby Atmos, Dolby Atmos Height Virtualization Technology, DTS:X, DTS Virtual:X, IMAX Enhanced, and Auro-3D support.
Two high-end models started shipping the 11.2-channel AVR-X6700H ($2,499) and 9.2-channel AVR-4700H ($1,699) that are now available through Amazon and other retailers this week. The 9.2-channel AVR-X3700H ($1,199) will begin shipping on July 15, while the 7.2-channel AVR-X2700H ($849) will go on sale on August 15.
