I have the Shunyata AC outlets, connected to a dedicated 20 amp line, feeding PS Audio PowerPlants with either AQ Tornado or Shunyata Delta NR power cables. I am happy with that. 

..depends what you want....I tried a few different ones and settled on Meistro which sounded to me the least colored.

I use the Pangea wall duplex for my Audioquest Powerquest 2.  This is specifically for my TV, Cable box, and router.  It is quite sufficient.  For the real deal, I use an Audioquest NRG Edison Duplex that is terminated to a dedicated 20 amp line.  Connected to that is an Audioquest Niagara 3000 for my entire 2-channel system.  It works exceptionally well and was a significant step up from the standard 15 amp line with a standard wall outlet.  The difference is remarkable.

If you are going to have a power conditioner than you absolutely should change the wall duplex to at least a respectable grade unit.  Even without a power condition there is still plenty of benefit by having a respectable grade wall outlet.  I find the Audioquest NRG Edison Duplex to be the best value, considering the materials and the build quality.  There are more expensive, but I don't believe they are necessarily any better for delivery of current.  You will increase the capacity of your system every time you increase the quality of ancillary components (and yes, I do believe that AC delivery is a component of an audio system).  The more you do for your system the better it will be able to deliver its capacity.  This applies to all applications, such as vibration management/control.  But that is an entirely different subject.  Regarding AC, I stick to my above statement.
