I installed the PD Creative power supply mod in a Node 2i powered by an iFi iPower Elite 5V power supply. I ran it with the stock power cord and shortly replaced it with an aftermarket power cord I had on hand. Prior to writing this I swapped power cords again and quickly went back to the better cord. I listen to Tidal and this upgrade was a game changer which I highly recommend. This changed what I thought was a pretty mediocre DAC in the Node to one that is highly listenable with hifi or MQA streams. Amazing what an external dedicated power supply will do. I now bypass the DAC in my Nova 300 and strictly use the Node with the analog outputs. W/o the power cord I now have a $1050 Node and I would definitely do it again. Note that the conversion board took 7 days to deliver from Poland. and took 30 min to install.
PD-Creative
anyone tried the PD-Creative(Polish) linear power supply mod to the Bluesound Node 2i?
