High-performance home theater is a wonderful thing. Onkyo is focused on providing a memorable A/V experience without totally wiping out your wallet, and it looks like they've hit a home run with the TX-NR7100.
For starters, all six of its rear-panel HDMI inputs support crisp 4K/120 video content. (The front-panel HDMI input supports 4K/60 video content.) It also has nine channels of built-in amplification, making it one of the most affordable receivers capable of driving a 5.1.4-channel Dolby Atmos system.
Add in built-in support for Sonos, THX certification, the latest video game processing technology, and Bluetooth streaming to your headphones (night owls, rejoice!), and you've got one heck of an A/V value on your hands.
The TX-NR7100 isn't just great for watching movies — it's terrific with music, too. Stream tunes from your phone or tablet via Bluetooth or Apple AirPlay 2. Play your collection of digital music files over your Wi-Fi network. Or use the built-in phono input for your turntable. You can even play high-resolution tracks from a USB drive.
If you're a Sonos fan, you'll be glad this Onkyo receiver easily integrates into your Sonos multi-room music system. Just add a Sonos Port, and you can send any music or audio source from the Sonos app to the receiver. When you fire it up in the app, the receiver automatically turns itself on and switches to the correct input.
The TX-NR7100 uses Dirac Live audio calibration — one of the industry's best room correction platforms. It measures the acoustics of your room with the included microphone, and then fine-tunes the output of your system to best match the unique sonic characteristics of your space.
