The verdict
It suits buyers who want a THX-certified receiver with working gaming features and Sonos or Klipsch integration. Onkyo still publishes firmware for it in 2026. Little independent review coverage could be read for this guide, so judge sound quality from a demo or user reports.

HDMI inputs 1 to 3 handle 8K/60 and 4K/120 Hz with VRR, ALLM and QFT, and the main HDMI output has eARC. It adds THX certification, Works with Sonos, AirPlay 2, Chromecast built-in and DTS Play-Fi. The main caveat is that its three other HDMI inputs are limited to 4K/60.
