That you for your effort, iFi people. A few questions: ^ does this mean that in the TiDAL desktop app, we select all 3 options: "Use Exclusive Mode", "Force volume" and "Passthrough MQA" ? ^ seems like quite a struggle, are you talking about the space in the FPGA or some other memory? Just curious. In general it would be easier for us to bear with you if we knew the scope of difficulty of the challenges your are facing here - as i.e. you now have clarified. - are there known unresolved bugs in 2.0.1 which were introduced in 2.0 but have not been present in 1.0 ? - will it be possible to revert back to 1.0 (or whatever the original version is named), after trying 2.0.1? Where could 1.0 be found? Again, thanks for your effort. I imagine the full complexity of the MQA module could not have been predicted until its full implementation.
