This suits a dedicated surround room where Dirac Live correction and THX certification pay off, and it is heavier and more advanced than a casual living-room setup needs.

Overview
Calibrating a surround room becomes automatic with this receiver's Dirac Live correction, which measures the space and adjusts output. It drives a full multi-channel layout, passes high-definition video through HDMI, and syncs volume with connected Sonos speakers around the house.
This receiver's Dirac Live correction and THX certification target a dedicated home theater rather than a background TV setup, so the tuning process and channel count reward a real speaker layout. Its weight and channel count are more than a small room or a soundbar replacement calls for.
Who it's for
Someone assembling a reference-grade surround room, with height or wide channels and a subwoofer to calibrate, gets the most from Dirac Live and THX certification here. A casual living room with a soundbar or a simple stereo pair does not need this level of processing or its added weight.
Pros and cons
- Dirac Live full-bandwidth room correction included
- THX Certified for reference-level theater sound
- Works with Sonos speakers with volume pass-through
- 8K and 4K video pass-through on HDMI
- Heavier and larger than a two-channel setup needs
- No listed multi-room streaming app beyond Sonos
Performance notes
Dirac Live measures the room with a microphone and corrects timing and frequency response across the full audio bandwidth, rather than relying on factory settings. THX certification means the amplifier stage and processing meet a fixed reference standard for theater-level output rather than an unverified claim. Sonos volume pass-through syncs the receiver's own volume level with connected Sonos speakers so levels do not need separate adjustment.
