Hello everyone.
In regard to the power issue that Amirm discovered, has Onkyo addressed this in any way?
Has anyone experienced any issues that can be attributed to this?
Best regards,
Charlie
It's a "nanny" circuit...
From Amir's perspective, one that is overly sensitive.
In actual use, by users in their home, you can search through the various forums, you just don't see problems reported of the kind Amir experienced during testing. - Basically the test pushes the AVR beyond what its designers made the "safe" limit...
People who run these AVR's with more "normal" speakers (ie: 6ohm to 8ohm, with reasonable efficiency... SPL/wm) have not experienced issues with them.
If you read through the details of the tests and the subsequent discussion - the RZ50 actually ranks pretty well, and is highly competitive with its main competitor the Denon X3700.
"Nanny circuit" issues during tests have come up before, and are not uncommon with Denon, Marantz, Yamaha, etc... - they don't actually indicate a problem, they indicate a protective design feature which clashes with a reviewers "stress test".
You need to decide whether it is a protection which will interfere with your use case, and therefore something you should consider seriously (very rare!) - or something which should be taken with a "pinch of salt".
Those of us who have inefficient or hard to drive (low impedance... 2ohm or below) speakers, already know that we will need external amps, and look at the AVR as primarily a pre-pro (for the front channels in any case) - and as a prepro, the RZ50 ranks quite highly among AVR's (check out its SINAD and Voltage output before clipping).
The tests provide raw data for your consideration, the associated comments are a subjective response by the individual reviewer - which may or may not agree / align with your needs.
