I also recommend strongly considering the Teddy Pardo external linear power supply for the Node. The DAC on the Node is mediocre. The Node’s streamer is very good. It sound great with my MHDT Orchid DAC with both the digital coax (Node -> MHDT Orchid DAC with output tube stage) and RCA to balanced XLR (DAC -> BAT VK-6i tube preamp) interconnects from Silnote Audio. They only sell direct, based in Roanoke, VA. Their line of cables are all top quality, great sounding - clean, tight, dynamic with no hard sonic edges - and affordably priced. They also have great customer service.
