Denon AVR-S750H 7.2 Ch 165W 4K UHD AV Receiver Home Theater Surround vs Onkyo TXSR494 7.2-Channel A/V Receiver
Buy the Denon AVR-S750H if you want more power, more HDMI inputs, and room to grow into a 7.2 or Atmos setup. The Onkyo TX-SR494 is the leaner pick for a simple 5.2.2 Atmos room on a tight budget. Onkyo's rated 60W per channel is well below Denon's 75W, and the Denon adds a third HDMI input and HEOS streaming. Check the live prices at each store before you commit; the gap between them moves.

Questions and answers
- Which is better for Dolby Atmos?
- Both decode Dolby Atmos and DTS:X in a 5.2.2 layout. The Denon adds more power and Audyssey, which usually gives cleaner height effects in a larger room.
- Is the Denon worth the extra money?
- If you need Wi-Fi streaming, six HDMI inputs, or more power, yes. If you only watch discs and stream from the TV, the Onkyo covers the basics for less.
- Which has more power?
- The Denon, at 75W per channel into 8 ohms with two channels driven. The Onkyo is rated at 60W per channel.
- Can I stream music to either one?
- The Denon streams over Wi-Fi through HEOS, AirPlay, Spotify Connect, and Bluetooth. The Onkyo has Bluetooth only.
- Which is better for a small room?
- The Onkyo's 60W is enough for a small room and saves money. The Denon's extra inputs and streaming still make it the more flexible choice.
- Do both support 4K HDR passthrough?
- Yes. Both pass 4K/60p with HDR10, HLG, and Dolby Vision. The Denon's ports are all HDCP 2.3.
