Onkyo TX-NR5100 Review and Specifications

| Updated: | ,

Onkyo's newest 7.2 channel receiver Onkyo TX-NR5100 sets the bar even higher with some of Onkyo's best features ever like Chromecast built-in and Airplay, six pre-outs with Onkyo's Dynamic Audio Amplification, Dolby Atmos, DTS Play-Fi, Dolby Vision, and Onkyo TrueHD. We've reviewed Onkyo receivers for several years now; they're always among our top picks because they offer incredibly high-quality specs and cinematic sound quality at an affordable price point.

In the past, Onkyo receivers tended to be more conservative with many features that were there but you had to get inside the menus or set up manually. The TX-NR1010 is a great example of this and it was one of Onkyo’s most popular models. Onkyo has now come up with the receiver that is perfect for almost every home theater or audio enthusiast who likes to tinker.
