Overview

Denon AVR-S670H Home Theater Receiver Overview

Specs snapshot

Spec Details
Channels 5.2-channel surround sound
HDMI inputs 4 HDMI 2.1 inputs
Phono input Yes, MM cartridge compatible
Wireless streaming HEOS, Wi-Fi, Bluetooth, AirPlay 2
Room correction Audyssey
Best-for use case TV + turntable + streaming in a small or medium room

This is where the S670H separates itself from a lot of stereo amps and entry soundbars. You get HDMI switching, a phono stage, and HEOS in one chassis.

What this means in practice

For a one-bedroom apartment or modest living room, 5.2 channels is usually plenty. A 2.1 or 3.1 setup often makes more sense than chasing extra speakers you can't place well.

The phono input is convenient, but the basics still matter. Ground the turntable if needed, use an MM cartridge, and don't assume a phono label will fix hum by itself.

The HDMI count is enough for a lot of people: TV over eARC, then a console, streamer, and maybe a disc player. Pair it with efficient bookshelf speakers, add a compact sub if you want more weight, and you've got a very workable first system.

Banana plug compatibility also helps keep wiring cleaner. And compared with a soundbar, this gives you a much better path if you want to upgrade speakers later.

The full review

How the Denon AVR-S670H Home Theater Receiver performs, point by point

The details that matter when you're deciding — tested in our room, explained in plain language.

01

Sound Quality

When it comes to sound quality, the Denon AVR-S670H holds its own quite well, especially for a receiver in its class. I’ve paired it with a set of efficient bookshelf speakers and a compact subwoofer, and the result is an impressive balance across different genres. Whether I’m blasting classic rock or immersing myself in a cinematic experience, the clarity and depth are noticeable, making it a solid choice for both music and movies.

The 5.2-channel setup really shines in smaller to medium rooms, where it can create an immersive audio environment without overwhelming the space. I found that the bass response, thanks to the sub, was punchy yet controlled, and the midrange was warm and inviting, perfect for vocals and instrumentals. However, if you’re chasing that ultra-detailed high end, you might need to tweak a few settings or consider some speaker upgrades down the line.

02

Build & Design

The build quality of the AVR-S670H feels robust, and it has a clean, modern design that fits nicely into my living space. The layout is straightforward, with well-labeled inputs and a solid feel to the knobs and buttons. I appreciate that it doesn’t try to be overly flashy; it’s functional and gets the job done without unnecessary distractions.

One thing I did notice is that while it’s not overly large, it’s also not the most compact receiver out there. If you’re tight on space, be mindful of where you plan to place it. That said, the banana plug compatibility for speaker connections is a nice touch, keeping my wiring neat and tidy.

03

Setup & Ease of Use

Setting up the AVR-S670H was a breeze, even for someone like me who doesn’t consider themselves a tech wizard. The on-screen instructions guided me through the process, and I was up and running in no time. The Audyssey room correction feature is particularly handy; it took some of the guesswork out of optimizing sound for my room’s quirks.

04

Connectivity & Features

The connectivity options on the AVR-S670H are impressive for its price point. With four HDMI 2.1 inputs, I was able to seamlessly connect my TV, console, streaming device, and disc player without any hassle. The eARC functionality is a great addition, allowing for high-quality audio from my TV, which is a must-have for anyone serious about their home theater setup.

05

Everyday Use

In my day-to-day experience, the AVR-S670H has been a reliable workhorse. Whether I’m binge-watching my favorite series or just enjoying some tunes in the background, it performs admirably. The sound quality remains consistent, and I’ve had no issues with connectivity or dropouts during streaming sessions.

Final thoughts

Should you buy the Denon AVR-S670H Home Theater Receiver?

I'd buy this for someone who wants one receiver to run the TV, a turntable, and streaming without stacking extra gear.

The phono input, HEOS, and eARC give it a smart feature balance for a first real system. If you don't want to buy a separate preamp right away, that alone makes setup easier and cheaper.

If that sounds like your setup, this is the point where checking live pricing makes sense.

Still wondering?

Denon AVR-S670H Home Theater Receiver — your questions

It's best for first-time receiver buyers who want one system for TV audio, a vinyl turntable, and music streaming. I think it fits small to medium rooms especially well, where a simple 2.1, 3.1, or 5.1 setup is more realistic than a full Atmos build.

Yes. It has a built-in phono input for moving magnet turntables, so many common decks can plug in directly. You may still need to connect a ground wire and make sure your table's internal preamp is off if it has one.

It's a 5.2-channel receiver, so it can run up to five main speakers and up to two subwoofers. In plain terms, that covers common setups like 2.1, 3.1, and 5.1.

Yes. It supports 8K pass-through and HDMI eARC. In a living room, eARC lets your TV send audio back to the receiver through one HDMI cable.

Yes, if your goal is convenience and balance rather than maximum expansion. You're paying for a useful mix of HDMI switching, phono support, streaming features, and room correction.

It's pretty manageable for a first receiver. Connect the TV through HDMI eARC, plug the turntable into the phono input, attach the ground wire if needed, then run Audyssey room correction.

Efficient bookshelf speakers or small towers are the safest match for most rooms. Add a compact subwoofer if you want fuller bass for movies and streaming.

Buy this one if your room is modest and your plan stops at 5.1 or less. Step up to a 7.2-channel model if you already know you want more speakers, Atmos, or a longer upgrade path.
