Can AC Outlets really make a difference?


I have high quality reference power cords and line conditioner. Will a high end ac outlet really makes a difference? Any recommendations? Thank you.

Not at all, it is just that the people silly enough to spend money on that junk are not willing to admit it. It is all a serious joke taking advantage of people who do not know any better.

What do you care if we waste our money? Difference may be that we have actually tried different outlets while others on this forum have not.
