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

“When one upgrades the wire and it improves the sound at least as much as when one upgrades the components the wire is connected to, and for about the same cost, what more justification does one need?”

You’re so full of it...mc. Do you ever go back and read your posts? Since you don’t own Node 2i, your explanation (justification) is utterly out of context. 

I own Vault2 and a $500 power cord on this type of component is total waste of money. 

I use a Wireworld Electra Mini C7 with the Node ~ good results. But I would first try a VooDoo C7 adapter with your existing power cords.

Tried Audioquest, Pangea. Wireworld mini Stratus,  Wireworld mini Aurora and Signal Cable magic digital.
The Signal cable and Wireworld Mini Aurora are both great match with the Node 2i. 
I kept the WW mini Aurora only because it was longer. 

I'm very pleased with my Cullen C7. I also auditioned 
Wireworld, which was excellent, but the Cullen has such an expansive soundstage.

Considering Wireworld Mini-Electra, Cullen C-7, and Voodoo Vision Digital Cable for Vault 2. Already use Wireworld Starlight 7 ethernet cable from wall port to Vault. Vault plugs into Furman PFI20 power conditioner. Rest of system is described in my profile. One concern is that Voodoo cable might be so heavy/stiff that it pulls Vault off shelf or raises one end. Curious to get thoughts of group.
