any suggestions on what to replace Bluesound Node 2i with

Bluesound updated the Node 2i in June 2021. They have changed DACs and made other improvements, such as adding HDMI. Is the new Node worth a look?

Oh, have I learned my lesson chasing down the rabbit hole with streamers . While there is some differences , i have found that just adding a dac to the node was more than suffice , hell even the dac in the node2i isn’t too bad on its own . In the end just enjoy the music !!!

I did the same with Pawel. Great guy and very helpful.

He steered me to the SBooster 5V/3A LPS to use with his PSU interface upgrade(which was a snap to install). I am using a modestly upgraded power cable as well.

With my Classe SSP-800 DAC the Node 2i really swings.

I upgraded from the Node to the Cambridge CXNv2 and have found it to be a solid upgrade.   I wanted to keep a simple interface across multiple services (similar to BluOS).   Also needed Spotify connect support.  Tried the Moon streamer/DAC and the Cambridge was clearly the best bang for the buck.  (Note: I also took advantage of the balanced analog outputs, so that likely played a factor as well).  

OP here. I am not just looking to replace my streamer. I am doing a major upgrade of my home theater system with a second subwoofer and a separate 3 channel amp to run LCR speakers. I am also replacing my ceiling speakers with much better ones. I am also replacing speaker wire and cables with much better wire. Adding a streamer is part of a comprehensive upgrade. 
Realistically how much of an improvement will a high end streamer make over a Bluesound Node 2i? 
I realized last night that listening to Qobuz with my Node2i was not that much better than listening to Apple Lossless through my Apple TV music app. 
If I buy the Lumin T2 it will cost about 10X what the Bluesound costs. Should I expect a huge improvement in the music for $4500 or will it be more subtle with somewhat better detail, separation of instruments a better soundstage? I am hoping that before I spend the money replacing the Bluesound I will be able to compare the Lumin to the Bluesound on my upgraded system.
