Hifisoundguy, I agree that power quality is a big priority. I have a Purepower regenerator since a dedicated line in my family room presented a complicated install. Using shielded power cords have also helped to improve the power delivery to my system. I will likely change my outlets from the FIMs I currently have to either Wattgates or Oyaide. For me, the variables that affect the power affect what I hear from my speakers as much or more than many of the other variables and tweaks.
