Synergistic Research Tesla Plex SE ac receptacle

Sorry to put this under cables. One would think Audiogon would have a category for electrical tweaks.

How long did your Synergistic Tesla Plex SE ac receptacle take to break in, and at what point (in hours) did you hear it start breaking in?

NOW, this is assuming you did not come from a stock wall outlet, so please post if you've had say, PS Audio, or Maestro, or Shunyata, or Oyaide or FIM outlets for at least a year (so you have enough experience on the unit you had and it's been completely broken in).
Thanks
