I’ve had a Lumin T2 for two years, and have zero complaints. I’m contemplating upgrading to the X1. The Lumin app is solid, if a bit basic.
The T2 does support Tidal Connect, which lets you use Tidal’s iOS app directly, which is a much better user experience. The streaming services want you to use their app. Any third party app can only use subset of APIs the streaming service chooses to make public. Third party apps will always have inferior functionality.
I’ve read that Quboz is also working on a Quboz Connect tech. I’m sure when that’s available, Lumin will quickly add support for it (Lumin’s support is phenomenal), and I’ll ditch Tidal entirely.
I would personally disqualify any product that didn’t support Tidal Connect (or Q-Connect if/when it comes).
I haven’t had any experience with the hifi rose, but I suggest you listen to both and let your ears decide.
