Denon AVR-X2700H vs. AVR-X3800H: Is the 9.4-Channel 8K Upgrade Essential?

Calibrated bench measurement sample: Denon AVR-X3800H 9.4-Channel 8K Ultra HD AV Receiver.

Why the Denon AVR-X2700H Left Enthusiasts Wanting More

The Denon AVR-X2700H was a dependable workhorse when 8K and HDMI 2.1 first hit the market. However, it suffered from one notorious limitation: it possessed only a single 8K-capable HDMI input, and its 7.2-channel configuration meant you had to choose between two rear surrounds or two height Atmos channels. You could never experience full 5.1.4 or 7.1.4 immersive spatial audio. Enter the Denon AVR-X3800H 9.4-Channel AV Receiver, a component that redefines the receiver mid-tier.

9.4 Channels of Processing & Four Independent Subwoofers

The leap from the X2700H to the X3800H is immense. With 9 onboard amplified channels and 11.4 channels of pre-out processing, the X3800H allows you to run four in-ceiling Dolby Atmos channels simultaneously with surround backs. Furthermore, while the X2700H had dual subwoofer jacks that were internally wired in parallel, the X3800H features four completely discrete subwoofer outputs with individual level, delay, and EQ controls, completely eradicating room bass modes.

Full-Bandwidth HDMI 2.1 Across All Ports

Say goodbye to HDMI switchers. The X3800H equips six rear HDMI 2.1 inputs that all support 40Gbps bandwidth, 8K/60Hz, 4K/120Hz HDR pass-through, VRR (Variable Refresh Rate), and ALLM (Auto Low Latency Mode). Whether you connect a PS5, Xbox Series X, high-end gaming PC, and Apple TV 4K, every device functions simultaneously without handshake bugs.
