Or perhaps in the meantime, a way of grouping some of the most common devices like say Airplay and RAAT, even if that comes with a SQ compromise. I’d happily accept a compromise in that scenario, as I wouldn’t be ‘critical listening’ and it would be incredibly convenient - the world of Airplay devices would be open to me.
Of course, I don’t know if it’s just a compromised scenario, it may not be technically possible?
