Buy the Yamaha RX-A4A on the sheet — its 110W is both higher and stricter-measured than the Denon's 95W, and it states three HDMI outputs to the Denon's two. Buy the Denon AVR-X2800H if your speakers dip to 4Ω anywhere but the front pair, or if you're already in the HEOS ecosystem.
As tracked by Home Theater Builder: the Yamaha RX-A4A tracks at $1,600; the Denon AVR-X2800H at $999.How we verify this data →

Reading the numbers honestly
Power is close to like-for-like: 110W (Yamaha, 0.06% THD) vs 95W (Denon, 0.08% THD), both at 8Ω with two channels driven. The Yamaha's number is higher AND measured at the stricter distortion threshold — under matched conditions its edge is at least the stated 15W, though that's still under 1 dB. Corrections differ in family, not tier: YPAO RSC vs Audyssey MultEQ XT. Impedance guidance splits: the Denon states a blanket 4–16Ω rating; the Yamaha's curated rating allows 4Ω on the front pair but asks 6Ω+ elsewhere. Multiroom ecosystems are stated on both sides — MusicCast vs HEOS.
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 Yamaha RX-A4A drive the KEF LS50 Meta?
Yamaha RX-A4A states a 4Ω-minimum rating; the KEF LS50 Meta dips to a stated 3.5Ω minimum, a little below that floor. Most receivers handle a marginal dip at normal volumes — it's worth watching only at very high output on an entry-level unit.
Can the Denon AVR-X2800H drive the KEF LS50 Meta?
Denon AVR-X2800H states a 4Ω-minimum rating; the KEF LS50 Meta dips to a stated 3.5Ω minimum, a little below that floor. Most receivers handle a marginal dip at normal volumes — it's worth watching only at very high output on an entry-level unit.
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.
Buy the Yamaha RX-A4A on the sheet — its 110W is both higher and stricter-measured than the Denon's 95W, and it states three HDMI outputs to the Denon's two. Buy the Denon AVR-X2800H if your speakers dip to 4Ω anywhere but the front pair, or if you're already in the HEOS ecosystem.

Where to buy
CHEAPEST FIRST · NOT COMMISSION-RANKED
Yamaha RX-A4A
Tracked at PC Richard & Son · price not quotable from a search page
The Yamaha's power figure wins on both axes at once: 110W vs 95W AND 0.06% vs 0.08% THD, same 8Ω/2ch context — higher rated under the stricter test.
Impedance ratings differ in structure, not just number: Denon states 4–16Ω across the board; Yamaha's curated rating is 4Ω fronts / 6Ω+ elsewhere — a real constraint for low-impedance surrounds.
3 vs 2 stated HDMI outputs; both carry a curated 40 Gbps HDMI bandwidth.
Room correction families, stated: YPAO RSC vs Audyssey MultEQ XT — different systems, neither a tier of the other.
