It benched at 135W @ 8ohm two channel driven, which is pretty good in this market segment! (and above the rated power from the specs)
Typically most AVR's claim 70% power all channels driven - but I have not seen it tested anywhere. (it's rated power is 120W @ 8ohm stereo... so you would expect circa 84W max all channels driven... but it bettered its specs, so it may well achieve 100W/ch, but I have not seen it tested)
It's main competitor costs substantially more, and only achieves [email protected]

The "issues" on the lab bench related to the self protection (AKA "Nanny) circuit, which after 30+ seconds of continuous 5W output into 4ohm, knobbled the power output, reducing it to around 30W... and then requires a hard reset to bring it out of Nanny mode. - However, we have no evidence to date, of this happening in actual use in real life (as opposed to on the lab bench). Of course absence of evidence is not evidence of absence. But still... it is a fairly draconian nanny circuit.
Pre-outs provided an excellent output, one of the best in its market segment
Test is here, with all its controversy:
This is a review and detailed measurements of the Onkyo TX-RZ50 9.2 8K THX Certified AV Receiver. It was purchased new by a member and drop shipped to me for testing. It costs US $1,399. Looks like all AVR companies are trying to break the mold of just dual rotary controls to something...
