@2psyop Out of curiosity, what digital cable are you using between the Node X and your Denafrips? What cables are you using in the rest of your system? And what sonic chracteristics of your digital playback are you currently unhappy with... what do you want to achieve with the upgrade?
I am an Aurender dealer and just got the Node X as a trade in. Last night I demoed through a headphone stack between the Aurender N200 and the Node X expecting for the N200 to outright blow the Node X away. There was no doubt the N200 was better, but the Node X has definitely impressed me more than past Bluesound units. The difference would be as great as the Aurender N150, though it would still be an improvement.
Given a look at your virtual system and the performance tiers of your products, it may be worthwhile bracing your system with better cables (not knowing what you’re using) or looking into a good switch or other accessories which may make a greater impact for less or equal investment.
In my experience and with those of my clients, people find value in a dedicated streamer upgrade more often if their systems are truly able to render at very high fidelity. It’s not to say that your system doesn’t do that, but your virtual system doesn’t have enough information for anyone to weigh in properly on that. The last thing you want to do is invest $2500-5K on a streamer only to be disappointed in a marginal improvement.
