Onkyo TX-RZ50 & Onkyo TX-RZ30 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Onkyo TX-RZ50 rather than the Onkyo TX-RZ30.
Why Do I Recommend The Onkyo TX-RZ50?
- The Onkyo TX-RZ50 features 120 watts per channel at 8 ohms for stronger headroom and clearer dynamics in large rooms, whereas the Onkyo TX-RZ30 provides 100 watts per channel at 8 ohms.
- Onkyo TX-RZ50 supports 11.2-channel processing for creating a full 7.2.4 Dolby Atmos speaker layout, while the Onkyo TX-RZ30 supports only 9.2-channel processing.
- It includes seven HDMI 2.1 inputs for connecting more gaming consoles and high-bandwidth video sources, whereas the Onkyo TX-RZ30 includes six HDMI 2.1 inputs.
- The Onkyo TX-RZ50 comes with dual HDMI outputs for flexible multi-zone video or simultaneous TV and projector setups, while the Onkyo TX-RZ30 provides a simpler two-output configuration with fewer zone options.
- Onkyo TX-RZ50 features a larger power supply and heavier chassis for improved thermal management and sustained performance at high volumes, whereas the Onkyo TX-RZ30 uses a lighter power supply and smaller chassis.
- It supports advanced pre-out connections for all 11.2 channels to integrate powerful external amplifiers, while the Onkyo TX-RZ30 includes fewer pre-outs and limits external amplification flexibility.
- The Onkyo TX-RZ50 has a front-panel HDMI input for quick temporary connections to laptops or cameras, whereas the Onkyo TX-RZ30 lacks a front-panel HDMI input.
- Onkyo TX-RZ50 provides higher current capability to drive low-impedance speakers for consistent control of demanding floor-standing models, while the Onkyo TX-RZ30 has lower current reserves for challenging speaker loads.
Maybe the Onkyo TX-RZ30 price can make you comfortable because it’s a little bit cheaper than the Onkyo TX-RZ50. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
