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??

Crap !!!! Daaa no mentioning of the cable size no mentioning of how it can affect sound just another BS story. Absolutely amazing how a 40 year debate can be explained with $100 analyzer what a joke.

NONBELIEVERS:  Hear me.

I'm an EE since 1980. I would never fall for this noise people emit about cables making any difference -- audible or measurable. In the 80s and 90s I worked designing custom integrated circuits at a couple of the big-name manufacturers here in the US.

BUT THEN IN 1989, working through a pair of Mc60s, after recap, metal film, tube rolling, etc, I heard a *definite* difference in current-adequate power cables. Imagine my hard head being forced to believe. But there it was. A clear difference in clarity of bass, mids, and highs.

So now I am converted. I know less, but I have heard more, and I now believe. You should too.

 

There’s no 40 year debate here. This is thousands year old debate of random gimps entering conversations they should be no part of to share opinions they can’t substantiate.
 

The OP had asked for a power cord recommendation for a specific component within context of a specific system. And the opinions of those who never even stood within a distance to be able to read the make and model of these components and cables are pouring in. Hoarders of vintage low-fi stereos that retailed for $50 brand new 50 years ago that have captive power cords telling you there’s no difference in cables. Others with DIY garbage kits and low resolution speakers that have been listening to their systems at 115db levels for 30 years share their thoughts on how it’s impossible to hear differences between cables.
 

Gotta love the forums on the internet where you can obtain a legit qualified opinions on everything from cables to marriage counseling from people who have no experience in either. 
Keep it coming! Entertainment is awesome here!

That in-itself is a whole lot of opinion with a little sour to boot. You know the old Christmas Carol ‘Do you hear what I hear’ lol 

Thanks @audphile1 , you just saved me the time. If you can't hear the difference, you need a better system, or better ears. The only point I can agree on with the naysayers is that science cannot yet explain it.
