I don't know how the original question could be answered.
1. No one has heard all the DACs available.
2. Even if someone had heard all DACs that are available, the "best" would be an opinion which could very easily differ from listener to listener.
3. All DACs would have to be heard through the same system in the same room with as few variables as possible.
4. Just as an opinion was being formulated a new DAC would appear that could possibly throw the whole deal out the window, a moving target so to speak.
I'm always leery of "the best" threads.
