In this article, we will examine the similarities and differences between these two fantastic AV receivers and give you some tips about why the technologies are valuable and desirable. Then, we will give you full reviews of the products.
Speaker Channels
The greatest difference between these two receivers is the number of available speaker channels. The AVR-X2700H provides seven powered channels while the AVR-X3700H offers nine. In terms of setup, the more numerous channels offer greater flexibility in the arrangement of speakers you can configure in your entertainment area.
The extra channels let you set up ceiling-mount speakers and make routing speakers to a second zone better than the AVR-X2700H. That is because the remote zone speakers remove speakers from your main listening area, reducing the total number of channels to five, while the AVR-X3700H will still have seven channels in the main area available.
Connectivity Options
Connection options are similar and offer a wide range of opportunities to connect your favorite devices, gaming consoles, or turntable for the most complete audio experience. The HDMI inputs and outputs vary slightly, with the Denon AVR-X2700H having six inputs and two outputs while the Denon AVR-X3700H has seven inputs and three outputs. All are HDMI version 2.1.
ARC and eARC Compatible Components
One of the outputs on both models provides connectivity for an audio return channel and both support an enhanced audio return channel or eARC. Processing Dolby Atmos, DTS:X, and many other audio protocols are simplified by the eARC HDMI port.
Video Resolution Capabilities
All of the HDMI outputs on both devices are capable of video upscaling to 4k at 60 Hz, while one HDMI input is reserved for 4k/120Hz or 8k/60Hz video upscaling passthrough. This is an excellent option for connecting to one of today’s most popular gaming consoles.
Video and Sound Processing Technologies
There is little difference between the way the Denon AVR-X2700H vs Denon AVR-X3700H process sound and video. Both feature Dolby Vision compatibility along with Dolby Digital processing. Both handle Dolby Digital DD, DD+, EX, and TrueHD. They are also compliant with Dolby Atmos Height Virtualization, DTS:X, and DTS Virtual:X. Video capabilities include Dolby Vision, HDR, HDR10, and HDR10+.
Speaker Connection Options
Both models use binding post connectors for speaker connections. From there, you’ll notice a big difference in the connection options available. The Denon AVR-X3700H offers RCA preouts for advanced surround sound setups. The Denon AVR-X2700H only provides preouts for subwoofers and Zone 2 connections.
Advanced inputs
Audiophiles looking for a receiver that works with their turntable will appreciate that both models have a phono input. Both offer a pair of coaxial and digital inputs but don’t offer coaxial digital outputs. They also have a pair of digital audio inputs.
Tuning Capabilities
The Denon AVR-X3700H offers a more advanced version of the award-winning Audyssey dynamic eq program. The AVR-X3700H uses Audyssey MultiEQ XT32, a 32-bit version that offers superior tuning capabilities. The Denon AVR-X2700H uses the more basic Audyssey MultiEQ. Though less sophisticated, it is also an excellent tuning program that helps get the most lively sound from your speaker setup using the Audyssey dynamic volume mapping abilities.
