Denon AVR‑S570BT
no budget ceiling
The cheapest current-production route into real surround, backed by 12 sources — four 8K HDMI 2.1 inputs at $449, more high-bandwidth switching than anything near the price.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
No Atmos, no DTS:X, no room correction, no Wi-Fi. It decodes plain 5.1 and nothing above it, calibration is an on-screen setup assistant instead of Audyssey, and wireless is Bluetooth only — no AirPlay 2, no Spotify Connect, no HEOS. This is a starter receiver and it does not pretend otherwise.
Dealbreaker? Runner-up №1 adds Wi-Fi, AirPlay 2 and YPAO for ~$100 more ↓

Traps — this verdict avoids
Why the Denon AVR-S570BT is right for you
It avoids every trap below — and for just me, no budget cap, it is the pick because it delivers:
Phantom HDMI 2.1 ports
"Six HDMI 2.1 inputs" rarely means six fast ones — on most receivers only 2-3 inputs carry the full 40Gbps; the rest run at 24Gbps, which is fine for 4K/60Hz and not enough for 4K/120Hz gaming. We check which port count is real.
Channel-count math
A 7.2-channel receiver tops out at 5.1.2 Atmos — two height speakers. Four ceiling speakers (5.1.4) need nine amplified channels, which starts around $1,799. Buying 7.2 and planning a 5.1.4 ceiling is the most common expensive mistake here.
Wattage theatre
Quoted watts are measured with only two channels driven into 6 ohms — all-channels-driven output is 30-50% lower, and the numbers are not comparable across brands. Rooms under 3,000 cubic feet are fine on 80-100W/ch; bigger rooms want 120W+.
