It seems like no one else uses a Meridian 210, which I interpret as a bad omen.
I did order one for testing and it should arrive on Friday.
So I’ll be able to contribute a bit by writing about my impressions of it compared to Roon through Node 2i and Sense.
I updated my signature so that people can see what else is in my setup = what subjective colouring my impressions have.
Interesting - I didn't know Meridian released a streamer. Will look into it. I haven't heard it, obviously - but have had a lot of meridian gear over the years and it has all been fantastic, so I wouldn't worry too much.
