any suggestions on what to replace Bluesound Node 2i with


I am doing a major upgrade on my home theater system. I want to upgrade my streamer. I can spend around $4500 if I have to. My dealer played a Lumin T2 and the music, Tidal, sounded amazing. He said I would be okay with the D2 if I wanted to save money
Any one have any experience with the the Lumin's. I am open to other streamers, it does not have to be Lumin. Thanks

I’ve been using a Primare NP5 for the past 6 months after using a Bluesound node. I am really pleased with it. Gapless playback, solid built application and not overly expensive. Not to mention it sounds better and its Roon Ready. My only gripe is that it doesn’t output audio via USB. I will try adding an ifi power adapter at some point. I went this direction because I like trying out different DACs . But I only stream music for background noise or to sample an album before buying .

Has anyone tried what I have? I replaced the Node 2i's PSU board with a PD Creative PSU board interface upgrade and it is powered by an SBooster 5A/3V LPS.

I'm using an upgraded power cable with it...Must say, it sounds pert darn good with my Classe SSP-800's DAC.
I have a node 2i with the PD Creative dc power supply board upgrade.  Feeding it with an LKS power supply and upgraded dc cable.  Soft silver spdf (Nimak) cable to LKS Mh-da004 dac.  Also audio quest Vodka Ethernet cables through Etherregen.  Pretty pleased with result.  
I bought an Raspberry Pi 4 w/ HAT (allo digione signature). It has two separate power supplies, with a linear power supply for the output board and a switch mode for the raspberry pi board. 
Then I run coax tommy Schiit BiFrost 2. 
I cannot compare against anything beside a MacBook but I think it sounds stellar. 
I run Volumio which can be glitchy
