Power cord upgrade

I had AQ Tornado on my Aurender N200 and didn’t like it - too dull, narrow stage, mushy. Using Nordost Heimdall 2 now and also tried Frey 2. Both are better to my ears and in my system than the AQ. 
I would go with Transparent or Nordost especially if you already have the Hurricane on the amp unless you like soft and dark sound. 

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. 

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

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!

Science cannot explain how old the universe is. That number changes every 20-25 years. Oscilloscopes can’t tell me what my system sounds like. Nobody knows 💩. So that’s that for science. 

@1971gto455ho the sole responsibility of science is to produce theories and in best case scenarios the results that the scientists themselves will need to challenge to prove beyond reasonable doubt.
Until we have the means to measure what we hear with an oscilloscope and have it rendered on the screen as measurements, you have an argument but it isn’t a very valid one. I’m totally cool with it though, as I said before, if you osciloscopians, “measurements only” crowd, want claim you have a scientific proof and stick to your guns. Just know there’s more to it.
