Power cord that improve the soundstage the most?

No contest, the JPS Labs Aluminata. I've never heard an improvement like that from a power cord. I've been using Foundation Research LC2 filtered cords for a year now, and like them a lot - better than TG Audio SLVR (RIP, Bob), better than Argent Audio Brujo, better than the Elrod Statement II (of which I own a pair). Then I plugged an Aluminata loaner into my amp and it was like a whole new world opened up. They do everything better than the other cords I've tried. They are stupid money ($3500) but I have one on order.

I haven't tried some of the other heavy hitters - the Shunyatas or PADs for instance, but the Aluminatas were convincing enough on their own to get me to cough up the coin.

JPS Labs Kaptovator PC is not far behind at half the cost, still a silly price but works well with my pre & power amps. I was using PS Audio Statement PCs & the JPS is a significant improvement; Timbre & PRAT factors are some of its strengths IMO.

Here's what I think people should do (in order of importance):

1. Put in dedicated circuits.

If that's not possible then:

1a. Put in a power regenerator (NOT a conditioner!)

2. Get the best PC you can afford that has:
10 AWG conductors and,
A floating shield.

Get one for your amp and another for the regenerator if you have one.

3. Spend the money you budgeted for PCs for your front end stuff on a balanced power unit instead, and plug all your front end stuff into it. If you have a regenerator, plug the balanced power unit into it. If you have dedicated circuits, plug it into one that's reserved for your front end gear.

If you want to buy one more PC, you could get another 10AWG shielded for your DAC or CDP. Other than that, I'd leave everything stock.
