Disappointing as TX-RZ70 did so much better in all tests at Audioholics! It`s currently on sale for 2000$ or 1800$ open box so all hope is not lost with Onkyo as it even beats the 4500$ costing Marantz Cinema 30 in power output tests
@amirm .
- The TX-RZ70 produced very low distortion of 99dB SINAD (.001% THD+N) for the main channels and 86dB SINAD (.005% THD+N) for the surround channels via the multi-ch preouts.
- As shown with the SINAD vs Vrms graph prior, the pre-outs of the TX-RZ70 have plenty of clean drive (3-4Vrms).
- The TX-RZ70 was able to belt out
266 watts/ch at 0.1% THD+N and
299 watts/ch at 1% THD+N into 4-ohms with
both channels driven. This beats the
Marantz SR8015 which tested at 229 watts/ch @ .01% THD+N and 251 watts/ch at 1% under similar test conditions.
- The TX-RZ70 was able to muster
118 watts/ch at 0.1% THD+N and
133 watts/ch at 1% THD+N into 8-ohms with
seven channels driven. By comparison, the costlier
Marantz SR8015 tested 92 watts/ch @ .01% THD+N and 101 watts/ch at 1% with seven channels driven under similar test conditions.
- The Onkyo TX-RZ70 wins a bass ass award for its impressive CEA 2006 short dynamic burst tests results by delivering about
213 watts/ch for 8 ohms and 370 watts/ch with 2CH driven at 4 ohms and over
180 watts/ch with 7CH driven at 8 ohms.
- Distortion is low for the amp section of the TX-RZ70 measuring 85dB SINAD (.005% THD+N) up to at 50 watts/ch. That’s excellent!
