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

A better way to think of this is that good power cables don't improve sound.  Bad power cables degrade sound.  an inadequate power cable won't support short (picosecond) bursts of high current needed for fast dynamics and sharp bass.

I think you'll have trouble improving on the Pangea AC 9 SE.

@lalitk You must be a dream customer for a saleman.

To explain my comment, the pangea has everything I look for in a power cable, but it can usually be found for less.   

You want to expain what features you look for in a power cord that are so obviously superior?

@recklesskelly size does matter (in this case).  going to a 10 awg power cable, even a generic one from china, will get you most of the way there.

So do those in this thread who think power cables make no difference use 18 gauge lampcord to power their amps?

@secretguy the cable from your transformer to your home is generally at lest 4 awg copper but usually 2, 1 or even 1/0 gauge.  What do you propose upgrading it to?  It is several times larger than anything we plan to run to our system.  Sometimes it is aluminum but it is oversized to make up for the difference in conductivity.

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.
