I have used NBS Statement, Custom Power Top Gun HCFI and Siltech Ruby Hill but changed with Burmester 2.5 Power Cord for all the front end. It may not be better but I could not hear the difference between all of them and that means it is better because it cost much less.
However, the best is probably the Custom Power Top Gun HCFI for the amp and preamp. Nothing beats it so far.
