Onkyo vs Yamaha: 9.2 channels, THX and Dirac Live against Yamaha Aventage build and CINEMA DSP.
Updated 2026
Verdict
Buy the Onkyo TX-RZ50 if you want more channels (9.2 processing for 7.1.2 or 5.1.4 Atmos), THX certification and Dirac Live room correction included. Buy the Yamaha RX-A4A if you prefer Yamaha CINEMA DSP, YPAO and Aventage build quality and a 5.2.2 Atmos layout is enough.

You want a 7.1.2 or 5.1.4 Atmos layout, THX certification, and Dirac Live correction without buying a license later.
A 5.2.2 Atmos system suits your room, and you like Yamaha CINEMA DSP, MusicCast multi-room audio and the Aventage design.
You have a small room and a 5.1 setup. A less expensive receiver such as the Denon AVR-X1800H does the job with much less spend.
Yes. It is a 7.2-channel receiver, so it drives a 5.2.2 Atmos layout.
Dirac Live is generally considered the more capable correction system. YPAO is solid and easy to run. Both are good when you set the microphone carefully.
Check each maker for the current count. Both support 8K and 4K/120 gaming features.
Both have preamp outputs for external amplification, which helps with larger layouts.
