Any Bluesound Node2 owners

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

Well, i may be putting another Node2i in another system.
im putting together a 2.0 system with a Parasound Hint6 and a pair of
ML Sequel II’s
my front end analog will be my Denon dp59L
my hope is the internal dac in the parasound, bests the internal in the Node2i

Just FYI: Teddy Pardo has just released an upgrade kit for the new Bluesound Node, replacing the internal PSU with an external one. 

I now have the node2 hooked up to my Hint6 and the 30yr old MartinLogan Sequels, it sounds fantastic, so much better than the HT system.

I bypassed the internal dac understanding i would be topping out at CD quality i think, the Parasounds dac sounds great!

im streaming Bob James and Earl Klugh One on One Wow so happy
