Best power cable for Whest Audio PS30RDT SE



Hello everyOne,
I'm searching for a good power cord to feed my Whest Audio PS30RDT SE.
I tried the Shunyata Venom HC but strangely it cuts air and hights .. maybe too big (10awg)
Any suggestion?

The gold standard of power cords, the Synergistic Research Master Coupler. The only power cord so freaking good its been made for over 20 years and yet is still competitive with new power cords twice its price. As someone said the last time this came up, "A $1k power cord for $250? What's not to like?"
This is the Reference version

Might be able to find the original Master Coupler, who knows maybe for less although I have seen them for more. They come up all the time. Me, I would strike while the fire is hot.  
I agree with millercarbon's comment above. I'll also say that a 14 gauge power cord would most likely sound better than a 10 or 12 gauge wire.
Thank you for the suggestion linked ..  millercarbon .. unfortunately I need a schuko plug since I live in E.U
