I have (and love) a BlueSound Node 130. It has a great interface, and is easy and intuitive to use. For a while I thought about upgrading, but instead went with a DDC (Denafrips Iris DDC). It isolates the signal galvanically and optically, so the signal gets sent to the DAC (Denafrips Pontus II) cleanly.....I've done a review elsewhere here.
I'll keep what I have now as I'm completely happy with it, but at some point will want to compare the quality of that pair with higher end streamer. Price will be hard to beat, $600 for the Node 130 and $500 for the Iris DDC; damn good pair for $1,100
