Denon AVR-S670H Performance

Cinematic Audio and Video in the Living Room

The Denon AVR-S670H is designed to become the entertainment core of your home theater. It delivers a solid 75 watts to each of five channels, providing enough power for immersive surround sound in most living rooms or media spaces. With decoding for Dolby TrueHD, Dolby Pro Logic II, and DTS surround sound technologies, this receiver supports realistic 3D audio for movies, TV, and games.

User feedback highlights the clear and clean sound, with reports of zero hiss or static. The unit is praised for supporting Dolby Digital surround, ensuring most modern content is fully compatible and sounds as intended by the creators.

On the video side, the AVR-S670H stands out: it supports ultra-high-definition video with up to 8K/60Hz or 4K/120Hz pass-through. If you own a cutting-edge TV, you can enjoy razor-sharp picture quality, excellent contrast, and the benefits of advanced video technologies like Dolby Vision, HDR10+, HLG, and Dynamic HDR. This is particularly important for big-screen movie nights or next-gen gaming consoles.

Flexible HDMI and Multi-Device Setup

Ease of setup is a recurring positive in user reviews. With 8 HDMI ports, the Denon accommodates a wide range of devices—from Blu-ray players to gaming consoles and streaming sticks. The inclusion of eARC/ARC over HDMI simplifies your setup, allowing your TV to route audio back through the receiver for fuller sound—no more jumble of extra cables.

HDCP 2.3 copy protection ensures full compatibility with recent 4K/8K media, letting you enjoy premium content from streaming services and discs without issue.

The receiver also upscales 4K video to 8K, helping older media look better on new displays.

Ready for Gaming

For gamers, the AVR-S670H brings key features like Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and Quick Frame Transport (QFT). These optimizations help reduce input lag and stutter during gameplay, which is crucial for fast-paced action and competitive gaming.

Whole-Home Wireless Audio

A unique strength of the AVR-S670H is built-in HEOS technology. This allows you to easily extend music throughout your home—stream from services like Spotify and TIDAL, listen to internet radio, or play your own music files. You can group compatible HEOS speakers and control everything through the HEOS app. This flexibility is ideal for parties or for enjoying music in multiple rooms.

Smart Home and Hands-Free Control

The receiver’s support for major voice assistants, like Amazon Alexa, means you can control volume, switch inputs, or skip tracks with simple voice commands. This is a true convenience benefit—especially for families or anyone frequently switching between devices or media.

Bluetooth, Wi-Fi, and Reliability

Bluetooth connectivity is included, making it easy to stream from your phone or tablet. Wi-Fi provides another option, especially for casting music or using the HEOS features. However, some users report Bluetooth connectivity issues and occasional unit freezing. While many customers are satisfied with these features, you may want to keep the unit’s firmware updated for optimal stability and check device compatibility.

Everyday Use: Music, Movies, TV

Real-world feedback confirms the Denon AVR-S670H is easy to integrate with popular TVs and speakers. Customers praise the sound quality, noting the absence of unwanted noise, and highlight good value for the price. The unit’s multiple HDMI ports and robust streaming support make it a practical centerpiece for varied home entertainment needs.

Some users report connection problems or device freezing, mainly with Bluetooth. If wireless audio is your main focus, prepare for possible troubleshooting or use Wi-Fi and wired options for increased reliability.
