You can install them yourself [ AFTER cutting off the power at the main switch and checking carefully]. I was surprised how much better the FIM 880s were than the "hospital grade"ones I had been using on dedicated lines. Continuity checkers are a few dollars. I used the FIM because I am a dealer for their products but there are many good ones. I suspect they all sound slightly different but any of them will give you better results than a standard one or a generic "hospital grade" one.
I know you didn't ask about PS Audio but they make a very nice receptacle as well. I use their Power Port Premier's with dedicated circuits and I am very happy with them mostly blacker background.

If you really want to be anal, buy a big outlet box and install multiple outlets. Then you can quickly try each. Have I done this? Of course not!

I have installed seven different outlets on my two dedicated circuits. You can do it yourself. Be certain to turn off the outlet and follow the instructions as to where each wire goes.

Outlets do make a big difference. I will not say what my preferences are as I know there is no consensus on anything in audio.
