The TX-RZ30 stands out as a newer 9-channel AV receiver with HDMI 2.1a, dual independent sub outs, preouts, and Dirac Live room correction with access to DLBC. That combination makes it appealing for 5.1, 5.1.2, or larger setups, and the room correction is repeatedly described as a major upgrade over Yamaha YPAO and older Audyssey tuning. The main caveats are that Dirac has a learning curve, DLBC is a separate subscription, and the internal amps stay engaged when using preouts. A few reports also raise reliability concerns, including hiss or static and the need for good ventilation. It is a strong feature-rich receiver if those tradeoffs fit the setup.

You changed to entirely new speaker wire? You simplified speaker wire to a short 5' run to test what happens?
No, the wires are run through walls/floors. I had temporarily hooked up an old Denon 2308ci that was connected to all of this same equipment/wiring without any issues.

I'm going to pull the amp from my rack, bring it to my office and plug it into my EcoFlow, and test with my center channel speaker only. The others are too big to move. As of right now, regardless of which source is connected, the hissing/buzzing continues. I am also going to try run a wire to ground the cabinet.

BUT, to be fair, I have 3 other amps on that rack, connected to other speakers (yard, outdoor sub, and buttkickers) none of those have any buzzing (and neither did the Denon i pulled out); so it' likely a faulty unit.

Going to run a factory reset, and try again.

Sigh

Sorry that you're having that issue.
Sounds like one of the few issues Onkyo owners have reported!

Yup! No difference. I tried different inputs on my projector, thinking it was that. Was SOOOO excited to get Dirac at this price point.

Thanks! I saw those threads too. But then if you google Denon Hissing, you get similar results. So might be just across the board?

Hmmm interesting, haven't seen/read anything about that with D/M.

I own the 3800 and have setup 6 other Denon/Marantz with Dirac, none had that issue.

Unfortunately you might need to just return it.If you do curious to know how well their CS is?

I will mention I have also have setup PAC units including this one with Dirac & did not run into the issue.

I guess mine is going back. The static/crackling happens even when casting music to the built-in chromecast, IF a display is attached to it. maybe something wrong with the HDMI board?

I'm torn between return for another unit or just return for refund. Something else that's new to this setup is that when I am watching an Atmos track movie in Emby, skipping causes the audio to drop out. but a double or triple skip makes it come back. Seems to be an hdmi handshake issue. I haven't had this with my older Denon units.

Tempted to return for refund and just wait for a comparable Denon to go on sale. Then again, to get this featureset in a Denon, Im looking at several hundred dollars more.

I will say, I hate the volume/info overlay on the Onkyo - even my aged out x5200w had a better on screen overlay. Why is Onkyo's so 2000s feeling?

Are your HDMI cables new, latest and greatest 2.1b etc cabling?

Hmm I think so. BUT in the grand scheme of things, an older cable standard should just prevent you from accessing a feature, NOT introducing crackle/static.

EE was very helpful - accepted my return right away, and offered a discount on a new, not-open box replacement order. Strangely, he did say that Open Box only has a 1yr warranty.

Yes, sure, but if you can point to "when I do this, bad things happen" then it only makes sense to replace the associated cable with a new standard to see if the problem still exists. I agree static shouldn't happen, but if you then were at 120hz and the old AVR couldn't do that, that's something new that's happening, and hence new problems could then show up. Worth a quick test; would take seconds. This is why I replace all cabling when I swap out TV, AVR - and why I have the installers put multiple cables in the wall, in case one is bad. Of different brands, too. Smilie
