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.

I'll second the above 100% , I'm currently burning in a Furutech GTX NCF (R)  Prior to was the PS Audio Premier and AQ Edison . Each has a different signature but I'm really liking what I'm getting from the Furutech those far. So 10awg dedicated 20amp line and shot for the top.
Another resounding yes. I use PS Audio power ports currently, and rewired most of that circuit with higher grade sockets. Even that made a difference, and my household power sucks. Considering a dedicated line as well. 100% convinced it makes a difference. Will probably kick the receptacle install up to full ++ audio grade.
