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??

When I had PSM 156 I swapped connectors on classic cord with Furutech rhodium plated FI-28 and FI-32. Made a really nice improvement. 

OP Iam not surprised the Heimdall and Frey will work in favor of AQ . I used AQ storm series on amp and preamp.

Also, OP…don’t buy the puritan ultimate cord without ability to return it. I tried it, gave it few weeks of break in and sold it. It was harsh, thin and fatiguing in my system with all pass labs amplification at the time. I eventually got rid of psm 156 as I found it to be an overall bad fit for my system and I only ran source components off the puritan. 
good luck

Using the Shunyata Denali 6000 v2 I have had great success with both the Shunyata Sigma v 2 and Kubala Sosna Elation power cables.

I’ve been impressed by reviews of some direct sellers that are worth exploring as they offer high value and generous free trials.  On the lower end there’s the Ice Age OFC “Frankencable” and on the pricier side there’s the Snake River Signature both of which seem to punch well above their respective price points.  Best of luck.
