Awesome as you say... it's an Amarra thread so i'll also be brief but I feel like all of this talk is relevant for comparisons!
I've been experimenting more with Amarra for Tidal and I do agree that the sound quality is very good indeed - to my ears 2 elements that l feel relatively comfortable speaking about are extra depth and sparkle up top. Could be placebo. I do feel the difference is quite subtle and i'm still in somewhat of a honey-moon period with Tidal anyway given the improvement I felt over Spotify. It's a shame the interface of Amara is so disappointing especially when it accompanies the premium service from Tidal.
I'm going to give Roon a go - it put me off slightly that they wanted card details up-front and you can only cancel by email... especially when such large sums of money are involved - but I'm sure it'll be fine!
I watched a video of someone giving a walk-through of Roon - it did look very nice but I'd like to ask you how effective you think it would be using it
solely for Tidal music as opposed to it being primarily used for local media and it being a nice option for Tidal to fill in the gaps? I have some local media but certainly not enough to form a real foundation for how the whole thing would work.
The other issue I guess I would have with it is that I presume you can't make playlists in Roon that would simultaneously appear in Tidal for offline syncing on iPhone for my music on the go? In that sense I guess I would find myself using the Tidal desktop app as well... which isn't ideal. Perhaps these features will get added in time?
Although Roon is pricey its one of the few times where it seems like good value for us UK'ers. For Tidal $19.99 apparently = £19.99 whereas $10 (£6.50) a month for Roon doesn't seem so bad.
