Power cords for Coincident Frankenstein and AMR DP-777 <100$

Essrand,
I appreciate that  we all have our individual budget limits, I'd offer this advice. Wait and save more money and buy high quality cords on the used market. Your Frankensteins are high resolution and transparent amplifiers.  You'll easily hear the benefits of the higher  quality power cords. A 100 dollar power cord could be a relatively good value choice but may not extract all the performance your amplifier has to give. 
Charles, 

What charles1dad said, with extreme prejudice. Save up and get the best you can and try not to go any smaller than 10 gauge. 

All the best,
Nonoise

In principle I agree with you guys. Sadly expensive power cords will have to wait their turn. 

The current queue for my system is:

Preamp (Duh! looking for used Shindo)
better 300b tubes (right now I have Shuguang black treasure)


I got excited about power cords and jumped the gun after reading this post: https://forum.audiogon.com/discussions/changed-the-power-cord-to-signalcable-magic-power-cord-on-my-...

This guy got an improvement with 69$ PCs which bettered his speaker upgrade!!!

Hello Essrand,
The Black Treasure 300b is a very worthy tube (I used them happily for two and a half years ). To better them you'll have to spend more money. For what you'd pay for better 300b tubes that money would get you two good used power cords and a good AC wall outlet  (they make a difference ). Definitely various reasonable routes to consider. In my opinion addressing the AC power (power cable, outlet and upgraded fuses ) is fundamental and money well allocated towards towards improving an audio system.  Choices 😊
