DAC connection: which type gives highest fidelity?


Suppose one wants to connect two digital devices, as in a streamer to an outboard DAC or similar.

Which is the highest fidelity connection?  USB, coaxial, or other?

Thanks!

Building on their comments, the popularity/ubiquity of USB is pointing to manufacturers continuing to work towards optimizing it. They realize it will be most likely to be used (e.g. during reviews) and weak USB implementation will be an Achilles heel for product sales. 

Remember that I2S was originally used inside equipment and isn't standardized. Caution to do model-specific research if you're planning to pair devices with it. There are potential compatibility issues. Cheers,
