Power conditioner vs use of a audio grade outlet?


If I have a $7000 Power conditioner and really nice power cables is there a need for audio grade outlet? Maybe it's a dumb question but if I didn't have this other good stuff maybe I should get an audio grade outlet.

Pangea seems to offer a good outlet for about 100 bucks.

I'm using Audioquest 15amp nrg wall warts with my Niagara 1200 and 3000, which  plugged in with AQ Blizzard Extreme powercords. I went as far as to replace the plastic outlet covers with true wooden ones as well.

Furutech GTX-D

Oyaide and PS Audio make some very good ones as well, but I've settled on the Furutech for now
