Here is a list of reasonable powercords that work well with the X 350.
The Sidewinder gold retail $350, the Mojave retail $550 both by Shunyata.
The Master coupler and the Reference both work well.
The Pass I personally do not like with the Custom powercords although they are really good with Roland gear.
The gut wire works well as does the Supernatural by Audio prism.
There are others I am sure but those are the ones that I have tried.
My 2 favorite cords on the X 350 are expensive the Electraglide fat man and the Synergistic DR square.
Hope this helps.
