Power Cord for Accuphase Amplifier

I have a new Accuphase P-4600 amplifier and am looking for a power cord to replace the stock. So far I’ve tried the Cullen Crossfire and the IceAge OFC Frankencable. While both cables have worked well on my source components they have not performed better than the stock on the amplifier. So to those who have Accuphase amplifiers what power cable has worked for you?
 

As I mentioned in other threads Accuphase strongly recommends that you use only the stock cord and so far that has been the best. The. other two have resulted in a darker sound with less soundscape openness. 
 

I’ve been trying to stay under $500 for the cord but would be willing to go a little higher if it improves the amps performance.

Actually Accuphase documentation is pretty strongly worded. It has a Warning that states use of aftermarket power cords are Prohibited.

,,,aftermarket power cords are Prohibited.

Yet you are soliciting advice about aftermarket power cords. Expect a visit from the Japanese electronics police as soon as you plug one in😨

Wow PROHIBITED by who? Doesn't make sense at all...

It would make sense if there were a warning states use of cheap power cords like 22awg are prohibited since they are dangerous. but we're talking about 10awg aftermarket power cables on amazon. A question for you what's the definition of "aftermarket power cords"?

In another document they state that any replacement cord must meet their specifications. Which I would assume is the same as the provided cord. I thought it odd. But so far their cable does perform well. If they find out I changed the cable I will be asked to perform Sepuku.

They’ll just have you eat fugu sushi prepared by a trainee. 
So what’s so special and unique about the stock cord. What gauge is it? My Pass Labs X260.8 mono blocks came with stock cords that are 3x14awg stranded conductors (probably decent quality copper with molded connectors), branded Cheng something. The amps are 260w/ch into 8ohm with 35w in Class A, each. The stock cords are adequate. The amps are on the 12awg dedicated circuit. If you haven’t run a dedicated circuit yet that’s your ballpark $500. Run 2 circuits - 1 for amps/analog, another for digital. And keep stock cord then see how it is.
