Any recommendations for aftermarket C-7 power cord for Bluesound Node 2i

I'm currently using the Bluesound Node 2i with NAD M51 DAC. I'm thinking about upgrading either the power cord to one of the ones mentioned here, or upgrading the whole power supply to linear (Teddy Pardo and Fidelity Audio in UK offer LPS upgrades). Any thoughts on these options?

Has anyone here pimped out their Node 2i with a PSU interface card and Linear power supply? Supposed to make a big difference to sonics...

That is my next project when my Node 2i arrives. 

Good stuff on the power cables. I've heard a lot of good things about the Triode Digital American. I'll look into the Wireworld too. I thought the Node 2i had a C15 IEC but maybe not.  

@vinylshadow Yes it is worth while especially paired with a good LPS. Much more refined sound and lower noise floor. I bought the one from Poland on eBay.

Thanks Alex. I was looking at the interface card and switching power supply on Pawel's website but wanted a linear power supply so great that he sells the interface separately. I will order one.
Which linear power supply did you get?

Are you using an upgraded power cable?

I was considering the Triode Wire Labs Digital American. I am using Pete's High Power Dig. American for my UberBuss power conditioner...While it might be the way to go, a $500 power cable for a $540 Node 2i deserves some thought.

The Wireworld Mini Electra that many use and recommended is $160.

Wonder if there is a big difference besides the price?

@vinylshadow I've used a few different LPS. Tried the Uptone LPS 1.2, Paul Haynes SRT4, and Mojo Illuminati. They are all fantastic and didn't notice a huge difference TBH. I have my best PC's on my DAC, Amp and Conditioner so unfortunately the LPS gets the cheapest cord but still performs great. If you don't have a switch or some sort of filter for your Ethernet connection I'd recommend putting some attention in that area as that is going to make a huge improvement for the Bluesound as well.
