Best Digital Interface

It is my understanding that Asynchronous USB may be the best interface for digital transfer to a USB DAC. If the DAC has  Asynchronous USB then it basically owns the signal and basically re clocks timing, bits etc for a more perfect transfer if fed USB? I am streaming from a Node 2 into an RME DAC. I know there is no USB output from the Node. I have a few questions: 
1. Is there a Coax to USB adapter available? Does this make sense? 
2. Are there other reasonably priced (>1k) streamers that have USB output?

Thanks!

Hey there.

No it does not make sense to add coax to USB. 

Over the last 15 years or so clocks have gotten really good though, so if you are running a modern player and DAC the benefits of USB have diminished somewhat.

Without USB isn't the clock in the Node 2 running the show?

Whether a USB or traditional digital output sounds better are completely dependent on the Streamer / DAC components you have. It’s basically a question of which component is better (simplified answer). I have used both. On my headphone system I have a USB only DAC, so I use that. It is a very good DAC. On my main system I use traditional digital... it sounds ever so slightly better... I mean so little it is silly to talk about.
