Can a better power cable make a difference if NOT plugged directly into an outlet?

I’ve had a positive outcome using Shunyata Venom NR power cables into their power distributor.

I’ve also installed a whole house surge protector to allow me to plug amps into the wall. I didn’t notice a difference and use the power conditioner because of its mechanical breaker.

Good luck in your quest- I am surprised about what impacts what and why in so many ways!

Txp1,

I can't find the leftover cable from my installation,  but did text the electrician on what he used. If memory serves, it was Romex SimPULL 10 AWG.

BTW, I mentioned "even a generic Chinese cable will get you most of the way there".  

Sorry but I forgot to mention that you have to reterminate them.  If you are the kindof guy that does this, you'll be pretty good for cheap.  If not, try ice age cable in MI.  Good power cables at reasonable prices. 

I just realized I gave an incomplete suggestion above and wanted to clear it up.

Here is one if the chinese cables I reterminated lately.  Link to my google photos account.

When I bought my AR6, they had I believe 3 different levels of feeder cords for it ranging from the one I have to a very expensive one.  Having said that, I’m using the AC9 SE mkll cord on my Hegel, but have it plugged right into the wall. Mostly because the AC9 is so darn stiff that it kept pulling itself out of the amp when I moved it even a little to reach the AR6.
