For my amplifiers (Prima Luna PL2/ tube, Prima Luna PL5/ tube, and Outlaw RR2150), I use PS Audio Punch . At the time I went the PS Audio route because they offer ground pins which screw out. I had ground loop issues with both Prima Lunas that I could not isolate and disliked having a heavy duty power cord plugged into a cheater plug.
For my Musical Fidelity CD PRE 24 (preamp/ cd player), I use the MF supplied power cord. It is a quality, thick cord and it fits nicely in the back of the component. Not all cords do that.
For everything else I use these NAIM $ 35 stock power cords that Gene Rubin Audio sells on eBay. I purchased a half dozen or so of these cords about 6 or 7 years ago and they work ridiculously well.
In all honesty, I don't know whether power cords widen soundstage, or not. I doubt my less than golden 55 year old ears would have noticed anything like that 20 years ago. I thought that fiddling with speaker placement or buying bigger, badder, speakers widened soundstage. I listen for a quiet background and power cords can affect that.
