The best fuse I tried is the Power Matrix by a small manufacturer Power House. The dealer related to me that these are more than a fuse and include some sort of RFI absorbing material. It may sound ridiculous but I can discern a sonic difference when my equipments have installed these. I understand these are carried by very few dealer however.
I also tried Isoclean, but much prefer the Power Matrix in being more detailed and refined. Isoclean products are priced much higher in the US than they were in the Far East where they were manufactured.
