I agree with the pessimists here:
As long as the individual companies involved try to gain as many advantages as possible for themselves, there will be no agreement. The issue has been around for many years now – and apart from Audinate, no one has managed to get something off the ground that everyone else wants to participate in.
As bad as it sounds, Dante will probably remain the lowest common denominator for the foreseeable future.
I don’t think it’s a sensible investment for A&H to develop a card that only individual users need. Something will have to change in the market first – and that includes the cooperation of as many manufacturers as possible.
Of course, we would all be happy if Milan became widely accepted. But it’s just not that far yet. Apart from Dante, there are only isolated solutions so far.
