The U1 I have was considerably improved with the Sbooster power supply. The Node worked well with a USB out into the Iris and then out into the Pontus via I2S. The sound was exceptional. However, once you have the Iris, it ONLY has a USB input.
Connection options from Node to Denafrips Iris to Pontus
What cables do you recommend to connect from a Node to a Denafrips Iris to a Denafrips Pontus? I'll be using XLR's from the Pontus to my preamp.
