I use Custom Power Cords. I tried a number of others and then read the Rowland reviews in The Absolute sound. The reviewers used the Model 11, which retails for about $280. They also make a model called Top Gun, about $600, which is supposedly great for front ends. They can be bought from amusicdirect.com. I bought one on AudiogoN and am very pleased with it. Another cord I like is the ESP Essence, but the Custom Power Cord is the best.
