Thanks @oddiofyl @mahler123. I have literally been all over the map trying to find if there are differences in Coax vs USB. It seems it's almost a split but more leaning towards USB a tad. I know like everything else it's so subjective. Problem is I don't have a USB to try so I'd have to buy one. I currently have a Transparent Premium Coax. I'm looking at DH Labs Mirage for USB...
Yes, the Node is already life changing-LOL! I had held out so long (and swore I'd never stream) because my router is on another floor from my rig and moving it is not an option. So I felt like without hardwire streaming would be a waste. I realize the Node does WiFi but my WiFi in my house SUCKS! Then someone pointed me towards the TP-Link Powerline adapters and I now have hard wired in my room-also life changing, LOL! So I pulled the trigger and got the Node for $399 brand new. And right out of the gate on its own it honestly sounded better than cd. I was FLOORED. I never ever expected it to sound that good. So now that I have switched Pontus from CD player to Bluesound I want to make sure I am squeezing every ounce of quality I can which led me to the USB vs Coax dilemma...
