Main trade-off
Denon AVR-S570BT
Only four HDMI sources can remain directly connected.
Head-to-head
Choose the S570BT for a five-speaker system with four fast HDMI sources and simple Bluetooth playback. Choose the S670H when six source connections, HEOS or a direct MM turntable connection matter more than a fourth 4K120 input.
Before you choose
A four-console 4K120 setup favors the S570BT, while a six-device mixed-video rack favors the S670H.
What this is based on
The S570BT has four total and four fast inputs. The S670H has six total and three fast inputs.
Main trade-off
Only four HDMI sources can remain directly connected.
Main trade-off
Only three inputs accept 4K120.


Compare Denon S570BT and S670H for a five-speaker room, including fast HDMI inputs, HEOS streaming, turntable connections and room setup.
Choose the S570BT for a five-speaker system with four fast HDMI sources and simple Bluetooth playback. Choose the S670H when six source connections, HEOS or a direct MM turntable connection matter more than a fourth 4K120 input.
Winner by situation
S670H provides only three suitable fast inputs.
S570BT has only four source inputs.
S670H supplies a dedicated MM input.
Both meet that speaker and music plan. Check source count before paying attention to network features.
What matters in practice
A four-console 4K120 setup favors the S570BT, while a six-device mixed-video rack favors the S670H.
The S570BT has four total and four fast inputs. The S670H has six total and three fast inputs.
With music supplied through HEOS, the S670H does not need a separate HDMI music streamer for that job.
The S670H includes network streaming and the S570BT relies on Bluetooth or connected sources.
Two added height speakers would require replacing either receiver.
Both have five amplified and five processed main channels, with a documented 5.1 layout.
Check a documented speaker layout against HDMI sources and external-amplifier plans.
Does not support this setup
This layout is outside the documented speaker configurations.

This layout is outside the documented speaker configurations.
A powered subwoofer is separate from the speaker-channel count. This checks one main room. Zone 2, bi-amping and unusual speaker assignments need another manual check. Allow ventilation space and confirm HDMI settings, cables and speaker impedance before installing.

Denon, AVR-S570BT
Four modern HDMI inputs for a five-speaker TV system. Bluetooth handles casual phone playback without a network music setup.

Denon, AVR-S670H
A five-speaker receiver with six HDMI inputs, HEOS streaming and a moving-magnet phono input. It suits a room that will stay at 5.1.
Meaningful differences
| What changes | Denon AVR-S570BT | Denon AVR-S670H | Why it matters |
|---|---|---|---|
| HDMI inputs | 4 | 6 | A fifth source fits directly on the S670H. |
| 4K120-capable inputs | 4 | 3 | The S570BT has one more high-frame-rate input despite fewer total sockets. |
| Music connection | Bluetooth | HEOS, network streaming and Bluetooth | The S670H can play network music without using the phone as a Bluetooth source. |
| Dedicated MM phono input | No | Yes | A phono-only turntable needs a separate stage with the S570BT. |
| Automatic room setup | Auto Setup | Audyssey MultEQ | The calibration software differs even though both remain five-channel receivers. |
What you give up
Recommendation switch
Choose Denon AVR-S570BT. Its four HDMI inputs all support the documented 4K120 path.
Choose Denon AVR-S670H. Its six HDMI inputs accommodate two more connected sources.
Choose neither. The documented processing or internal-amplifier layouts do not cover this requirement. Choose a receiver with the required physical configuration.
What matters in practice
Four HDMI sockets are enough for a console pair, a disc player and a streamer. That list changes if a computer and set-top box also stay connected. The S670H accommodates six physical sources, but only three belong on its 4K120 inputs. A high-frame-rate source inventory can therefore reverse the usual assumption that the more connected receiver is the better gaming fit.
The S670H is useful when records or network music are everyday sources. Its MM input accepts a compatible phono-level turntable, while HEOS supplies supported music services over the network. The S570BT works with a turntable that already has a line output or an added phono stage, so the absent socket is an extra-equipment question rather than a ban on vinyl.
Both are sensible five-speaker receivers when the room will stay that way. Neither offers physical height channels. If adding ceiling speakers is already on the shopping list, a seven-channel model changes the wiring plan in a way that HEOS or a higher power figure cannot. Powered subwoofer jacks do not create spare full-range amplifier channels.
