Quietest BUDGET high-current power cord?

You state that you want absolute silence from your power cords.

Do you have noise in your system now that you expect to ameliorate with power cords to your amps?

Do you have experience with other power cords not being absolutely quiet, and that you can trace specifically to the power cords and not to another element of your system?

Have you treated your power at the source...like with a whole house power filter at the breaker box?

Tvad, Absolute silence... in an ideal world, that is. "Black" is an adjective often used to describe the space from which sound emanates. I've heard the difference in the various pcs I've tried on my front end. I expect the same will apply to the back end. Like everyone, I'm hoping to minimize the trade-offs, and quiet (ease, naturalness, effortlessness...) is a quality I cherish. I've worked painstakingly, step by step, starting from the front end, to reduce noise in my entire system and I'm pretty happy with the result. For instance, I recently commissioned an outboard linear power supply for my dac and added vibration control to all my hardware. In addition, I employ some modest power conditioning and replaced my wall outlet with a high grade OCC unit. (I rent so I can't go behind the wall.) It seems prudent to exercise the same care in dealing with pcs.

The only cords I have experience with at the ~$250 street price are Oyaide Tunami GPX. I use three in my system mixed with a few cords costing much more, and the Oyaide cords hold their own.

...also, the Envinronmental Potentials EP-2050 sells for about $700 and provides commercial grade power filtration and surge protection at your breaker panel.

IMO, spending the money here makes more sense than spending it on power cords at this juncture in your system.

Tvad, My whole system is fed through a PS Audio Quintet, a component I much admire. The improvement it has made is profoundly audible.
