Hey @Christian_Jensen1, welcome to Roon, and Roon Community! It’s great to have you with us.
I’m happy to help with a couple of your questions and hopefully clarify things a bit.
I can’t think of a time when this ever happened, and if it did, it would be a huge anomaly. Once Roon Ready certification is obtained for a device, they’re good to go and ready to enjoy worry-free. I have a couple of older devices in my home that are Roon Ready but have been superseded by newer models, and they all still work great.
Roon Ready devices are the highest level of certification and offer the greatest degree of integration with Roon. They have embedded Roon technology, offer a range of benefits, and use our custom in-house RAAT (Roon Advanced Audio Transport) streaming protocol, which is explicitly designed for Roon. It’s a collaborative partnership between Roon and the manufacturer that guarantees a superlative experience.
Roon Tested devices also offer a reliable and enjoyable experience. They just don’t use our RAAT network streaming method — instead, they use a wired connection like USB or alternative streaming methods such as Chromecast, AirPlay, Sonos, etc.
The Onkyo TX-RZ30 is an example of that. It offers both AirPlay and Chromecast, plus wired connectivity options. But, it doesn’t have Roon tech integrated inside the device.
This helpful video features Enno Vandermeer, one of Roon’s founders, discussing the differences between Roon Ready & Roon Tested.
Another thing you can consider if the Onkyo TX-RZ30 is the best fit for your needs is simply connecting a Roon Ready Bridge device to it. That device would establish a connection between your Roon Server and the Onkyo. The Roon Ready Bridge is visible to Roon and passes the audio stream through that device and on to the Onkyo receiver. It’s not exactly as seamless as having a Roon Ready device, but it’s a viable alternative.
This method is a very popular workaround among Roon customers who are looking for a way to make their existing systems Roon Ready. So much so that I’m currently writing a new How to Roon blog article on this very subject. It’s one most frequently asked questions we get from customers.
A couple of popular devices for doing this are the WiiM Pro Plus, and WiiM Ultra, any of the various Bluesound Node devices — or if you’re a DIY enthusiast, installing Roon Bridge on a compatible device you build yourself. You’ll find loads of threads with details on that here in Community.
Just something to think about if your heart is set on the Onkyo TX-RZ30
