Bluesound Node130 LPS upgrade...

I started with a HEOS Marantz receiver, then a INNUOS Pulsemini/zen lpsu, now I have the Pulse. Not that this is the brand you should buy from, just that upgrading to a different device will make your ears happier. The Pulsemini/zen lpsu fits your budget and such. I was so impressed with the mini that I was able to get my dealer to give me full trade on the mini because it was less than a year from purchase. And jumped on the Pulse. I suspect that might be a path for you, hopefully you will find some joy in the music. 

I got the LHY LPS for my N130 and it went together easily and has performed flawlessly for over a year.  I use it with USB out to a Mytek Liberty DAC. I like a lot of small boxes on my shelves!

I have seen used Aurender NH100 streamers for as little as $800 used. I would consider going this route. It’s FAR superior to my Bluesound Node 2i.

I would recommend saving for a better streamer. You will just lose more money selling the node with power supply than just selling the node. 

I would agree with Jallan and Audphile1: save the money and get a used better streamer. I got the node, installed a quality LPS and made no difference to my years. Then I upgraded to a Innuos Zen mini and BIG sound improvement. I was using a Denafrips Venus for both streamers. 

By the way, I'm using Qobuz and the app of the Innuos is better than the Blue OS in my opinion.
