To build on this, I can't discern any difference between running my NODE through a Schiit Modi 3+ via digital out and simply taking the analog out direct into my Adcom GFP-750. And the Modi measures great; obviously the NODE's DAC is mediocre at best from a measurement standpoint, but audibly no difference to my ears.Pretty sure this is not what you want to read but honestly, I can't tell the difference between the NODE internal DAC and the Topping E50.
The reason I'm getting the Topping D30 Pro DAC is to give me volume control and balanced output so I can get rid of the Adcom. Don't need all the other inputs and capabilities of that excellent preamp.
