Can a Bluesound Node 2i power supply really be upgraded?


I mean...by improving its components, not with a YOUR preferred streamer brand...;-)
Sure, you can upgrade the C-7 power cord. We all get that.

But, what about the power supply.
I only see 3 options:

1. Fidelity in UK
2. Some dude in Poland selling on eBay
3. Rumors of Teddy Pardo making one for the Node 2i.

It has to be DIY for the first two and not really what I'm looking to do with my streamer - I mean, if i'm going to to a DIY LPS upgrade, I'd like it to be easier to buy.

Anybody know anything or actually made it work?

i think the ps upgrade for the node would help the sound of its mediocre dac the most... not sure if there is bang for the buck if it is used as streamer only... maybe knowledgeable persons with real insight into the construction of the node 2i and how the various sections of the unit could comment...
Yes I have the Polish one and it's a great upgrade. I'm only using it as a streamer and pair it with a good LPS. Easy to install and best bang for the buck upgrade in my system. No question.

Question is, if you spend the money on the the new board and a quality linear power supply, are you adding $600 or more to it? Might be better to look at another option. I have a Vault 2 and I’m considering moving on to a Lumin U1 Mini, which I’d probably still throw on a Teddy Pardo. Shame BS didn’t just build these devices with the cheap external switch supplies. 
@adg101 I've done the comparison with a $10k streamer (I won't say the brand but PM me if you'd like to know). Still preferred the PSU upgraded BS and used to $$ for home improvement projects.
