The Onkyo TX-RZ70 is the flagship of the RZ Series: a THX Certified 11.2-channel AV receiver delivering 140 watts per channel. It uses ESS Sabre DACs, a massive high-current amplifier, Dirac Live room correction and full HDMI 2.1 8K video with seven inputs, and includes a moving-magnet phono input. This substantial receiver weighs roughly 48.5 lbs and is finished in black.
Why This Model Matters
As Onkyo's top receiver, the TX-RZ70 drives a full 11-channel Atmos layout, such as 7.2.4, without external amplification. ESS Sabre DACs, Dirac Live, THX Certification and IMAX Enhanced mode combine for reference-level sound, and its 48.5 lb build reflects the heavy-duty power supply behind that performance.
