The fact that Roon runs on so many devices both commercial and specialized for audio enthusiasts is perhaps its greatest feature as well as one of its biggest burdens because clearly performance can vary widely depending on what devices are used and there are so many to choose from at all price points.
In my case, with the devices I use, things work very well for the amount of money I have invested.
Caveats;
1) if vendor support is a key issue for you there may be better options out there.
2) Given teh range of possible devices used, performance will vary widely. In general, as with most any computer hardware, you should get what you are willing to pay for.
3) Roon could do a much better job providing more clarity on what to expect with various commonly used devices. It would probably require a bigger investment by Harmon to be able to provide that information reliably but I think that would help elimiate a lot of angst with users who can only find out for sure via trial and error themselves. More technically savvy users will be better equipped to navigate the journey effectively than many.
One final note, as with any computer application, when things head south, a reboot may be needed to clear things up. With Roon that mean a reboot of Roon endpoint devices as well as the device the Core/server runs on. Sometimes router and any other devices involved with internet access.
If you have not rebooted all those together ever or for a long time, worth a shot to see if it helps. A lot of physical devices and services are involved with any network application especially when internet connections and performance of remote services at the other end that users have no control over (Like Qobuz, etc.) come into play. THings only perform as well as the weakest link in teh chain at any particular moment.
Roon is an awesome app with many unique and valuable features, but those with low tolerance for technical complexity are probably better served using other vendor specific streaming solutions.
If only one could have it all and it always worked perfectly and didn’t cost very much as well. A perfect world would be very nice indeed!
I have been a senior technical engineer/architect for a major financial services provider for many years. I also have a technical background in digital signal processing. So ai am used to this kind of thing and eat it up. Maybe when I retire sometime soon I will offer up my services to Harmon to see if I might be able to help take Roon to another level. That would be a fun thing for me to do in retirement but on a very limited part time basis only. Who know. Lots of fun things to do in retirement including all the usual audiophile trappings.
Cheers!
