The catch
Denon AVR-S570BT
Just four HDMI sources can stay connected directly.
Side by side
The S570BT is the right pick for a five-speaker system with four fast HDMI sources and plain Bluetooth playback. If six source connections, HEOS or a direct MM turntable connection outweigh having a fourth 4K120 input, go with the S670H.
Before you buy
The S570BT suits a setup with four consoles running 4K120, and the S670H suits a rack of six devices with mixed video.
Where this comes from
The S570BT has four inputs in total and four of them fast. The S670H has six in total and three fast ones.
The catch
Just four HDMI sources can stay connected directly.
The catch
Just three inputs take 4K120.

How the Denon S570BT and S670H differ in a five-speaker room, covering fast HDMI inputs, HEOS streaming, turntable connections and room setup.
The S570BT is the right pick for a five-speaker system with four fast HDMI sources and plain Bluetooth playback. If six source connections, HEOS or a direct MM turntable connection outweigh having a fourth 4K120 input, go with the S670H.
Which one fits
S670H offers just three suitable fast inputs.
S570BT offers just four source inputs.
S670H comes with a dedicated MM input.
Either one covers that speaker and music plan. Look at the source count first, before you weigh network features.
In practice
The S570BT suits a setup with four consoles running 4K120, and the S670H suits a rack of six devices with mixed video.
The S570BT has four inputs in total and four of them fast. The S670H has six in total and three fast ones.
When music arrives through HEOS, the S670H has no need for a separate HDMI music streamer to do that job.
Network streaming is built into the S670H, while the S570BT depends on Bluetooth or connected sources.
Adding two height speakers would mean replacing either receiver.
Each has five amplified main channels and five processed ones, plus a documented 5.1 layout.
Check a documented speaker layout against HDMI sources and external-amplifier plans.
Cannot handle this setup
This layout is not one of its documented speaker setups.
Cannot handle this setup
This layout is not one of its documented speaker setups.
A powered subwoofer does not count toward the speaker channels. This checks one main room. Check Zone 2, bi-amping and unusual speaker assignments yourself. Leave room for ventilation, and confirm HDMI settings, cables and speaker impedance before you install.

Denon, AVR-S570BT
A fit for a five-speaker TV system, with four modern HDMI inputs. Casual phone playback runs over Bluetooth, so there is no network music setup to deal with.

Denon, AVR-S670H
Six HDMI inputs, HEOS streaming and a moving-magnet phono input come on this five-speaker receiver. It makes sense for a room that will remain 5.1.
Spec by spec
| Spec | Denon AVR-S570BT | Denon AVR-S670H | In practice |
|---|---|---|---|
| HDMI inputs | 4 | 6 | The S670H can take a fifth source directly. |
| 4K120-capable inputs | 4 | 3 | Even with fewer sockets overall, the S570BT has one more high-frame-rate input. |
| Music connection | Bluetooth | HEOS, network streaming and Bluetooth | The S670H plays network music without the phone acting as a Bluetooth source. |
| Dedicated MM phono input | No | Yes | With the S570BT, a phono-only turntable needs a separate stage. |
| Automatic room setup | Auto Setup | Audyssey MultEQ | They are both still five-channel receivers, but the calibration software is not the same. |
Trade-offs
Change of plan
Go with Denon AVR-S570BT. All four of its HDMI inputs support the documented 4K120 path.
Go with Denon AVR-S670H. Its six HDMI inputs have room for two more connected sources.
Neither model fits. Neither the documented processing layouts nor the internal-amplifier ones cover this requirement. Pick a receiver that has the physical configuration you need.
Decision guide
With a five-speaker system, four fast HDMI sources and simple Bluetooth playback, pick the S570BT. Pick the S670H if six source connections, HEOS or a direct MM turntable connection count for more than a fourth 4K120 input.
A pair of consoles, a disc player and a streamer fit within four HDMI sockets. Leave a computer and a set-top box connected as well and that math changes. The S670H takes six physical sources, yet only three of them can use its 4K120 inputs. So if you own several high-frame-rate sources, the receiver with more inputs may not be the better gaming fit, which flips the usual assumption.
If records or network music are what you play every day, the S670H is the more useful receiver. A compatible phono-level turntable plugs into its MM input, and HEOS brings supported music services in over the network. The S570BT can still work with a turntable that has a line output or an added phono stage. Missing the socket therefore means buying extra equipment. You can still play vinyl.
Each of these makes sense as a five-speaker receiver, provided the room stays that way, and neither has physical height channels. Ceiling speakers already on your shopping list? A seven-channel model changes the wiring plan, which neither HEOS nor a higher power figure can do. Also, jacks for powered subwoofers do not give you spare full-range amplifier channels.
By the numbers
What we found across the AV receivers we compare, plus the checked facts behind each finding.
None of the 34 models checked meets all of “Stay with a five-speaker setup”, “Hook up four 4K120 sources”, and “Plug an MM turntable straight in”, so the pick goes to the closest practical compromise.
0 models fit, out of 34 checkedHow we countedThe count uses each product's current fit ratings for “Stay with a five-speaker setup”, “Hook up four 4K120 sources”, and “Plug an MM turntable straight in”. A need with no documented match is not counted.
