How are most audiophiles going from streamers to DACS

Ditto the USB advocates. When in doubt, start USB. There's a reason Aurender and Cocktail offer few if any other connections. True, all streamers and all DACs are different, but let the default choice be USB and regard that as the norm from which your components may ultimately be found to deviate.

I have the Denafrips Ares 2 connected by the coaxial with a decent 75ohm cable, far superior to the fibre optic connection which I also tried, but once I get a better streamer with usb out I will go that way.

ps they are a fantastic DAC, you won’t be disappointed. 

why not ?  i think it is the best possible solution

I don't use any of this stuff.
