I am using the thin RCA cables that came with it. The Node can also do optical, coax, and usb.
My Parasound Hint 6 has a built in dac of its own. It’s being bypassed by the Node dac via RCA.
Have you found better sound quality using one output over another?
I run USB to my Yamaha and use the DAC in my amp. I thought that if you use RCA it’s already analog and that means ur Nose did the conversion.
