Well, I am late to the dance, but it seems that all the discussion focuses on the Hi-Fi Tuning fuses versus stock fuses. I have always used IsoClean fuses as they came out well before the Hi-Fis and are or were cheaper. I have twice tried the Hi-Fi Tuning fuses versus the IsoCleans. IMHO the Hi-Fis are second best. I also confirmed to my satisfaction that the Hi-Fis are directional but that there is nothing about them that predicts which direction is best. All that you can do is to try all both ways. This is a real pain. The IsoCleans have clearly marked direction and in using about 20 of them, I have never found any mismarked. I first started trying different fuse direction at the request of Lloyd Walker with his motor controller.
I have also committed the sin of treating fuses with AudioTop contact cleaner and most recently with the Enjoy the Music award winning AVM paint. You only paint the glass, of course.
I have found all of this much more important than ac power conditioners and almost as important as lifting all but one ac ground. Although some recommend lifting all grounds, I have not found this to be best.
