The centerpiece of any home theater is the AV receiver. When you have a powerful projector and some fantastic speakers, the receiver helps deliver these signals to their proper outputs. Today, we’re looking at two receivers: the Onkyo TX-NR7100 vs Denon AVR-X3700H.
Which is better? Let’s find out.

Audio
When we tested these out, we noticed that the Denon had slightly more watts at 105 than 100 for the Onkyo AV receiver.
Onkyo supports Dynamic Audio Amplification, which delivers lossless audio we can hear. The Denon, meanwhile, allows you to use a 2 channel amplifier, while the Onkyo does not. In addition, the Denon comes with several sound processors, including Audyssey Dynamic EQ.
They also support their own room calibrations, with Denon’s coming with Audyssey and Onkyo using AccuEQ.
We tested both and knew both delivered stellar sounds, but Denon’s edged it out. The Denon has slightly more power and sound processors, which made the difference. However, we acknowledge that many won’t tell the difference.
Winner: Denon AVR-X3700H
Video
Meanwhile, the Onkyo TX-NR7100 is much more capable than the Denon with 7 HDMI 2.1 inputs as opposed to Denon’s having only one. Denon does have three outputs as opposed to Onkyo’s two, however.
Both can upscale to 8K and 4K with 60 Hz and 120 Hz, respectfully. They also support 3D. Regarding HDR support, the Denon does support Dynamic HDR, helping if you’re going from SDR to static HDR.
We believe the Onkyo excels because it has more HDMI 2.1 ports. When we were testing the Denon, switching ports every few seconds was a hassle. Denon having Dynamic HDR does not make much difference besides exceptional cases.
Winner: Onkyo TX-NR7100
Gaming
When it comes to gaming, both support features to deliver as lag-free of an experience as possible. For example, if you’re trying to set up tournaments, both ensure that the input lag stays to a minimum.
However, the Onkyo having more HDMI ports means connecting multiple PCs and consoles is a cinch. We were disappointed to learn that some devices on the Denon could not reach 120 Hz. Otherwise, the input lag is around the same.
Winner: Onkyo TX-NR7100

Both have their pros and cons. The Denon delivers more audio, and its setup assistance is much more intuitive. However, the Onkyo has more HDMI ports and can support more 120 Hz devices.
