Kimber Palladian PK10 vs PK14?


I'm interested in PK14 but can't find almost any information online about it. PK10 is generally regarded as a great power cord. Should I spend more and go with PK10 or save a bit and not hear any difference and get PK14?
The rest if the system is Simaudio Supernova, Marantz PM 11S2 and Hyperion 968. Cables by MIT CVT Terminator. Thank you

Yes, I ended up with 2 (I'm trying to keep it to a minimum with a cd player and an integrated) PK10 and don't think about power cords anymore :-)
any differences between PK10 with economy , gold , silver and palladian?

I am using PK10 with economy plug with my power amp now and just wondering how much improvement with other premium plugs?

Thanks
Just got 2 Kimber Palladian 10, for my monoblock, it’s like nbuying ew expensive monoblock...truly highend sounding.. Hard to refuse when you get good offer...
