I have been down that long upgrading the streaming road too. Like you I started with the Node 130, then added a Teddy Pardo LPS using USB to a Gustard X26 PRO. Then moved on to a Innuos Zenith mk3 still using the USB connection. Then got a DDC to use the I2s connection. Then switched to a Gustard A26. Still looking for more, forked out bigger moneys and got an Audio Mirror Tubadout V tube dac. Not to mention the ethernet switch, optical ethernet line clean-up and countless cables and fuses changes. Bottom line is, if you can budget it, everyone of those steps got me closer to music nirvana to my ears. To the point now that my streaming is arguably better sounding than my vinyl or CD gear, and that's no easy task in my house of stereo. Enjoy the journey!
