Power cord upgrade

I want to upgrade power cords for my streamer, Aurender A15 which currently has a Shunyata v14 digital.

And Puritan 156 which has the classic cord it comes with.

I believe in system synergy, so I am leaning towards Transparent, and/or Audioquest.

I have ARC ref5se with the Transparent Reference, and ref75se with the AQ Hurricane.

Guess my thought is the streamer and 156 PC are maybe a bottleneck. Won't know without trying, right? I am satisfied with the over all sound now, so looking for more of it. Make any sense??
