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
I use the Kimber PK 10 Gold WattGate and AG (silver) on all sources and preamp. The amp and line conditioner get the Kimber PK 10 Palladians with the AG and CU WattGates. I've used the PK 14 and while it's a good power cord go with the PK 10 since there's very little difference in the price. You can also upgrade to the AG connectors for a nice upgrade and have a very good power cord.
I installed the power cords in my system. Result - increased transparency across the spectrum. Bass is now under control. Valuable addition to my system that I don't regret.
When I installed the Kimber Palladian PK10 to my preamp. I heard a much better soundstage!It took my system to another level. I agree with the others.
