I too did not know if receptacles would make a difference, but instead of just accepting that fact; I ordered 7 different receptacles and did a many month comparison in my system and home. I kept the receptacles I liked and improved the sound, and gave the others away to friends.
To me this is the proper way to see for yourself, not blindly saying they make no difference.
By the way, a good friend loves the Cardas 4181 that I gave him so much, he wired his entire listening room with them; and had 2 dedicated lines installed.
