Walk me thru upgrading from my BS Node

First off I like the Node, the box was easy to install, form factor is excellent for my space (in a credenza) and the UI is excellent... and it has been bulletproof in terms of connectivity in the wireless mode. I have been pleased with the audio quality, but I haven't really compared seriously an upgraded solution

However after reading quite a bit of opinions across the digital thread I am really curious as to the order of magnitude audio improvement.

Budget is around $5-7k

I need the singular physical box to be reasonably small, it is in a credenza so I don't need to see a screen, I would prefer a set and forget interface like the BS... once it is up and dialed in, I don't need to mess with it...wireless only as the cable reach is prohibitive, connected to a Manley Stingray II...streaming Qubuz only...

The message I get is that the BSN is a good starter solution, but upgrading the DAC/Streamer is worth the ride..

Where to look, the YT reviewers (with the exception of Amir) just fawn over every product they test...
