Differences in electric outlets


Anyone have any idea if there is a real quality or other difference bewteen hospital grade duplex outlets and say those manufactured by PS Audio, or like audio companies?

I use two Porter Ports on two dedicated lines. I'm glad I have them but I don't believe there is any way to prove they are any better than stock hospital grade outlets. I certainly don't hear the orgasmic differences that others
attribute to this and other tweaks. I'm a skeptic. If I have to struggle to hear differences I believe those differences are suspect. If I can easily hear a difference, without prompting, then I believe it is real.
At present have a PS Audio power port in play
Was not expecting to hear much of a difference but what I heard was nice
It tightened up everything, gave a better bass definition and had it from plug in on.
From something that was tried on a lark and given to me as a gift, not much was expected but it workes others may work better, have not had the chance to try them but do intend to down the road.
This afternoon, I've just swapped out a PS Audio Power Port for an FIM outlet. Doesn't sound worse, can't say it sounds better. I suppose some would say you've got to let the new stuff burn in before you can tell if there's an improvement. I'm like Narrod, if I've got to strain to hear a difference, I'm skeptical there's anything meaninful going on.
Thanks to everyone thus far with you comments. I am somewhat of a skeptic as well, i.e. bought a few different power cords, PSAudio and a few others and think that the only one I really noticed a difference from the stock cords on was Audio Art Cables PC.

Photon46, is there a 'name' that FIM stands for, any reason you went with that?
Facten, not sure exactly what or who FIM is. The FIM880 was an outlet that has gotten good reviews and Galen Carol Audio extolls it's virtues. There are numerous testimonials from customers on his website ( gcaudio.com.) I had a chance to pick up a new one for a real good price so I thought I'd give it a whirl just to see if I'd hear a difference. FWIW, I have heard very substantive, immediate, no doubt about it differences between power cords. I've had such good luck enhancing my system with pc's, I couldn't imagine going with stock units anymore. As you say though, not all cords I've tried affected salubrious or audible effects.
