A terrific home theater value
I was stoked when Onkyo announced their 2021 home theater receiver lineup. It gives Crutchfield customers a fresh selection of feature-packed options, like the TX-NR5100 — one of my top recommendations for getting excellent picture and sound without breaking the bank.
I'm most impressed that this value-oriented model has four 4K/120 HDMI inputs — a rarity at this price point. It also has built-in support for Sonos (way cool), plus the latest video game processing technology for a smooth, lag-free gaming experience.
Ideal for a Dolby Atmos system
The seven-channel TX-NR5100 is ideal for powering a 5.1.2 Dolby Atmos or DTS:X™ system — that's the traditional five speakers and subwoofer configuration, plus a pair of upward-firing or in-ceiling speakers for overhead effects.
Enjoy music from a variety of sources
You get lots of fun options for playing music. Stream tunes from your phone or tablet through Wi-Fi, Bluetooth, or Apple AirPlay 2. You can even play high-resolution tracks from a USB thumb drive or networked computer.
Works with Sonos
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.
As a bonus, it will automatically turn itself on and switch to the correct input when you fire it up in the Sonos app.
