Bluesound Node130 LPS upgrade...

Do it.  I agree with with was said above about taking stock of your system and where you want to get it.  Over the years I've done many different upgrades and none have come close to the uptick in performance with the LPS on my Node.  I have it running into a relatively expensive external DAC and the first time I heard the results I said, "Holy SH!T."  I have no doubt it will be the best bang for the buck upgrade in your system.  Good luck and cheers.

I have a Node 2i, and since the new Nodes are days away, I’m wondering if the internal upgrades Bluesound promises may negate the power supply upgrades. 
I don’t know, but I’d wait until some reviews are out. I love the OS, so I’m hoping for the best…

Thanks for the feedback, y'all... have my main, 2 channel listening system, posted now with relevant pics.

I believe your testimonies answer the question of whether or not the PSU upgrade improves the sound regardless of external DAC input. I, too, love the bluOS as it integrates well with my Roon and has USB output. Also looking forward to the upcoming reviews of the not-yet-released Node Icon.

If I were to upgrade the streamer, I'd prefer one under $2k new but would have to have USB output, Roon ready, and excellent Android(phone) or IOS(iPad pro) app.

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!
