I like your idea of getting similar power cords. Check out Audioquest. One thing to keep in mind is that you can get cords that have different characteristics. For example, if you go with Audioquest they make a different cord for components that do not fluctuate a lot with power changes like a Streamer or dac and then different cords for components like an amplifier.
I think for the money this is a good way to go because there are many offerings within the brand and you’ll have the same general sound characteristics.
Good luck and let us know how you make out.
