Don't want to hijack this thread but...
I replaced Node 2i with optical Rendu package with linear power supply and FMC bundle. It is superb. I play only Tidal and control it using mConnect ($5.00) connected to the opticalrendu. I could not find the definitive explanation but I got it to work with no problems. I connect to my Pontus DAC using a USB cable.
