Upgrade from modified Bluesound Node 2i and linear power supply (LPS) ?

I installed the PD Creative power board mod with a MeanWell SMPS. After 120 hours burn-in it really sounds great.  I’m thinking about getting the Sbooster LPS for additional improvements but am curious if anyone found significant improvement from upgrading to the Lumin U1 Mini, perhaps with Sbooster. Or other streamer.

Did you upgrade from a Node 2i power supply board upgrade with a LPS to something else?
