I’m currently the owner of a Hegel H590 integrated. It’s not Roon-Ready yet, although it’s coming as an update. Now, the H590 only supports mqa on usb and I have connected it directly to my Synology DS918+, running Roon-core. Everything seems to work fine and Roon recognises the H590 dac, without any problems. HOWEVER, I have a Rotel Michi P5/S5 set on trial, which I REALLY like. But Rotel will not be Roon-Ready(as far as I know). As with the H590, Roon recognises the dac of the P5 just fine, via usb. My question is this: Will there be any sonic improvement in the H590, when It recieves Roon-Ready? And is it perfectly ok to run the NAS directly to the dac of the Michi, not being Roon-Ready?
We cannot speak to which setup will sound best, only you could determine that after careful testing in your own setup.
There are a few advantages to Roon Ready streaming like full Signal Path display in-app and hardware volume control that may enhance your listening experience. I recommend reading the RAAT (Roon Ready) knowledgebase article for more information.
I wouldn’t run your NAS directly into anything if possible. It’s power supply and fans are likely adding noise to your signal that you won’t hear until you remove. Best to use a dedicated player or wait until the Hegel is roon ready over ethernet.
