AI summary — not a quote
The Onkyo TX-RZ30 is frequently cited as a top-value 9.2 channel AV receiver, distinguished primarily by its inclusion of a Dirac Live license at no extra cost. Users appreciate its modern feature set, including HDMI 2.1 support, dual independent subwoofer outputs, and THX/IMAX certification. While its MSRP is high, it is a community favorite when found at sale prices (typically $750–$850), where it is often preferred over competitors like the Denon X3800H for its out-of-the-box room correction capabilities.
Pros
- Includes Dirac Live license without the additional fees required by many competitors.
- Excellent value proposition when purchased at sale prices ($700-$850 range).
- Supports 9 channels of amplification, suitable for 5.1.4 or 7.1.2 Atmos setups.
- Features a built-in web server for advanced configuration via a browser.
Cons
- Reported firmware bugs specifically affecting Dirac Live Bass Control (DLBC) speaker mapping.
- Intermittent HDMI-CEC issues where the receiver may fail to power off with the TV after updates.
- Dirac Live Bass Control (DLBC) is a paid upgrade, unlike the standard Dirac Live which is included.
- MSRP is considered high compared to the frequent and significant discounts available.

Marantz AV 10 In my opinion, best hdmi boards in the industry.
Marantz AV7706 (this is my 'good enough' choice, maybe)
I have the AV 8805 and it's a tank.
Marantz gear definitely lasts a long time - I have had an earlier processor for over 10 years and only had to have its display repaired.
Get a Marantz AV processor like the AV7806 on Accessories4Less, that will get you the 4K and Pre-Amp functionality for 5.1 and it will support Atmos out of the box
