Rose 150b should play perfectly with Roon. Listening to it now…;) If you see your meters dancing around, one would expect it would be your output that is causing the problem, rather than your network connection. On top of the advice above you might also want to check the gain settings for your analog out (XLR or RCA) which you can select to match your (pre)amplifier.
Problem with my Rose 150 b
I’m having a connectivity issue with my 150 and my iPad which I use to control the Rose. I can be playing music using the Rose App and just start losing the sound which is intermittent and comes and goes. I have the Rose connected to my AT&T router with an AQ pearl ethernet cable that is about 8’ long. I stream mainly Tidal although it happens when using Quobuz also. I have tried unplugging the 150 and restarting it also unplugging the router and rebooting it too. I haven’t reached out to Hifi Rose yet . Anyone have any thoughts. When this thing is working the sound is really nice. One other thing is that I have AT&T fiber which has 1000mbs speed.
