Thanks for asking. I haven't joined the fray here simply because I know so comparatively little about streaming technologies and equipment.That said, I've had Roon for about a week and I love it! I admit, though, that I may be like a man who has never seen a flower and is overwhelmed by the discovery of a dandelion. Perhaps there are orchids and birds of paradise up ahead....
Like others, I never understood why I should buy something that seems like just a nifty version of what I already own. For a few years now I annually have looked at the Roon website and found it bright and shiny--and not in a good way. So I'm quite surprised by how much I like it. Call me shallow but I love the easy interface that allows me to move easily between internet radio, my stored music files, and Qobuz. (Yes, I KNOW--I could do all this before I got Roon. But it's so much nicer now!)
I can't yet respond to the big question: how does Roon affect sound quality, if at all. There are too many variables in play for me at the moment (in my system but also in my life). That's up ahead.
I have a few quibbles, naturally, though I may just not yet understand all the features. While they talk the "audiophile" game, I wouldn't bet a nickel on their customer support. It looks to me like they put a lot of their energy into marketing some kind of bougie lifestyle. Blah. Still, I will report that I've already been emailing with Andrew at Small Green Computer, researching $$$ ethernet cables, pondering "bridges," and the like. Better and best, I've been listening to music. This may be the honeymoon period but I am enjoying it. (Ask me again in three months....)
Oh, and yes, plenty of queries, coming soon.
