I first discovered the magic of a better power cord in 1987.
I had Quad 63,but the Quad(thin as a hair)power cords weren't long enough.
So I got some cheap male ends and cobbled the old Quad IEC together with some 14 gauge solid core romex.
To my ears this was an improvement in body and dimension over the stock power cords.As it was to the next owner of those Quads who asked if the DIY PC's were for sale .
Now skip ahead about twenty years and I got into Annacondas and power conditioning and dedicated lines,with thanks to a friend who went that route a few months earlier.
I've never looked back.
It's really too bad some folks who claim to be music lovers still aren't hearing all the music they profess to love from their systems.
Power cords come in at various price points,but you can DIY .
Just don't cheap out on the connectors.
I would suggest the entry level Furutechs on some decent power cable wire.
Then as time and extra cash permit, upgrade those Furutechs to some of the better ones from them.
You can always re-use the entry cables you made elsewhere in a second system, Home theatre or to replace a few of those thrown in power cords some folks can't seem to part with.
I'll agree with you that the stock power cords will sound alright,but if the music really matters, you should investigate the power products that are needed to bring that music to you.
