Buy the Yamaha RX-V4A if you'll stream music — its stated Wi-Fi/AirPlay 2/MusicCast stack is the biggest stated difference, and its 80W at 0.06% THD is the slightly stronger honest rating. Buy the Denon AVR-S570BT for the higher stated HDMI bandwidth (40 vs 24 Gbps) and a 6Ω rating with no switch-flipping.
As tracked by Home Theater Builder: the Denon AVR-S570BT tracks at $449; the Yamaha RX-V4A at $650.How we verify this data →
Neither of these entry receivers pretends to do Atmos, and that shared honesty is the right starting point: both are 5-channel processors per our curated data. The differences live in streaming, impedance, and HDMI bandwidth.

Reading the numbers honestly
The Yamaha's spec sheet does something rare: it states Dolby Atmos and DTS:X as FALSE — a stated no, which our three-state booleans record as a real fact, where the Denon's sheet simply omits the fields. Power is near-like-for-like: 70W (Denon, 0.08% THD) vs 80W (Yamaha, 0.06% THD), both at 8Ω with two channels driven. Impedance is a real fork: the Denon states a 6–16Ω range while the Yamaha states 8Ω speakers (6Ω via a switch) — neither is rated for 4Ω loads, and the Yamaha's floor is the more restrictive as shipped. On connectivity the roles reverse: the Denon states 40 Gbps HDMI bandwidth to the Yamaha's 24, but the Yamaha states Wi-Fi, AirPlay 2, and MusicCast where the Denon's sheet states Bluetooth with no Wi-Fi field in our data.
Compatibility · computed, not written
Checked against a bookshelf that dips to a stated 3.5Ω like the KEF LS50 Meta: KEF LS50 Meta
Can the Denon AVR-S570BT drive the KEF LS50 Meta?
Denon AVR-S570BT states a 6Ω-minimum rating, and the KEF LS50 Meta dips to a stated 3.5Ω minimum — well below that floor. By its own published spec this receiver is not rated for a load like this.
Can the Yamaha RX-V4A drive the KEF LS50 Meta?
Yamaha RX-V4A states a 6Ω-minimum rating, and the KEF LS50 Meta dips to a stated 3.5Ω minimum — well below that floor. By its own published spec this receiver is not rated for a load like this.
Computed from the catalog's normalized fields — the same fields the builder's compatibility engine reads. A missing field reads as "can't check", never as a pass.
Gaming & connectivity · answered from the spec sheets
Can the Denon AVR-S570BT and Yamaha RX-V4A pass 4K/120 through?
The Denon AVR-S570BT states 40 Gbps HDMI bandwidth — enough for full 4K/120; the Yamaha RX-V4A states 24 Gbps HDMI bandwidth, below the ~40 Gbps full 4K/120 needs.
The verdict
Buy the Yamaha RX-V4A if you'll stream music — its stated Wi-Fi/AirPlay 2/MusicCast stack is the biggest stated difference, and its 80W at 0.06% THD is the slightly stronger honest rating. Buy the Denon AVR-S570BT for the higher stated HDMI bandwidth (40 vs 24 Gbps) and a 6Ω rating with no switch-flipping.

The RX-V4A states Dolby Atmos = FALSE and DTS:X = FALSE — stated noes our three-state data preserves — while the S570BT's sheet omits the fields entirely; both are 5-channel processors per curated data, so neither runs height speakers.
Near-like-for-like power, both 8Ω/2ch: 70W at 0.08% THD (Denon) vs 80W at 0.06% (Yamaha) — the Yamaha's figure is higher AND measured stricter.
HDMI bandwidth is stated 40 Gbps (Denon) vs 24 Gbps (Yamaha) — a real gap for 4K/120 sources at the entry tier.
Streaming asymmetry: the Yamaha states Wi-Fi/AirPlay 2/MusicCast; the Denon states Bluetooth, with no Wi-Fi field recorded in our data.
