Power cable Advice...

A more serious answer. 
 

This is a video of an interview with the founder of Shunyata. At about 10 - 11 minutes he starts going over what a power grid is and does. This should help.
 

I recommend getting an Audio Quest Hurricane just for your amp to start with. The improvement you get will completely shock you. The largest difference you will hear will be on your amp. Once you do this, it is likely you will want to re-think your investment strategy. Either go Hurricane for the other components or drop down a level for the components to reduce the overall expenditure. The improvement on the amp will likely convince you to the former strategy.

I spent a year auditioning high end amp power cords and was dissatisfied with all. Each either failed to improve the sound in all dimensions or tipped the tonal balance in some way. Then a minute with a Hurricane my search was instantly over.

I have not been impressed with Audio Quest in the past. But the Storm generation is a completely different story and a breakthrough. It does not shift the tonal balance, it dramatically drops the noise floor, without imparting a sonic signature, so more dynamic and quiet. The Hurricane and Dragon have been the buzz of the industry the last couple years for good reason. 
 

I suspect there are at least two innovations… the battery thing and the plugs on each end are really tight… I mean really tight. You’ll have to hold the front end of your fifty pound or heavier amp so not to move it when plugging in. 
 

The Hurricane on my power amp quickly brought my year long search for the right power cord to an end. 

Makes it sound better. 

OP,

Great deal. No question great choice. I have no doubts you’ll hear a great improvement.

Yes, great trip isn’t it. Good memories.

@steakster

Yes my trip down was very similar… lots of water fights. But we stayed in the boats. That seemed safer.
