I have been using Tidal/Roon/element X for the past 4 months or so, while it may not be perfect, I didn't notice any issue on Tidal integration with Roon to affect my listening pleasure or habit, perhaps it is a personal preference thing? Also I have tried on a few occasions using MA app to stream Tidal direct to element X, I didn't spend a lot of time on it to be honest, but it didn't occur to me there's any usage issue, may be I am just lucky?
Again I use my X exclusively as a Roon Endpoint for headphone, while also using Roon with another DAC for my speakers, I can simultaneously play different streams of music to different DAC, without any issues I can detect.
We might also note that, although this is not a very good reason, MA is focusing on getting their Mini-i 3 on Roon certification and Tidal Connect, perhaps their manpower is gearing toward that side at the moment? Again not a very good reason but a few of us have pointed out they probably have a very small team.
