I use the gold plated Furutek outlets and find them to be a nice upgrade over stock outlets. You should call Cable Co. They probably carry every outlet on the market. They'll give you honest recommendations, as well.
Your Favorite AC Outlets
I am getting ready to re-do my AC runs from my junction box to my listening room; going to add dedicated lines for my monoblocks. I want to upgrade my wall receptacles to good quality isolated grounded outlets. Have you tried the PS Audio outlets? Is their higher priced gold plated outlets that much better than their cheaper model? What brand(s) do you like best?
