Just to put in my 2 cents worth, I got the PD Creative update from Poland and installed it in a node2. It then requires an out board linear power supply which I didn’t know when I did it.. however I got one from Amazon and installed a synergistic black fuse, and used a thick shielded 2.5mm cable to hook the power supply to the node. Let me tell you this is no joke! It was like a new component. Crystal clear, excellent sound stage, and “dead” I mean “dead quiet”.I can’t believe this made such a huge difference. Highly recommended.
