A Better Bluesound AC Cable?

Do the Pangea SE MKII. Takes some of the brittle brightness off and tightens everything up. I am a late convert to power cable influence, but it does make a difference when the cable can stabilize voltage. Definitely worth the $50 on a $499 unit (I did mine on the Node 2i)

Shunyata makes what looks like a high quality adapter.

Can anybody explain why use a PC which only has a 2-prong plug?

Wouldn't a figure 8 (C7) IEC to 3 prong plug have an advantage over the 2 prong type? 
Noise would be drained via neutral and ground conductors to the 3rd pin on the plug (a proper ground).

I had the Pangea and it was loose. 
Now I have the AudioSensability cable, it’s a good fit and it has improved the sound. 

I’ve been wondering this myself for my Node 2 and someone here recommended a Nordost Purple Flare as a good replacement. I’m also eyeballing the Shunyata Venom 14.
