I have to correct my other post, Pass told me to get a 4A fuse just to be safe.
I know that a lot of people like the Isoclean fuse, I used it myself for a while.
I've since tried the PS Audio copper fuse, the HiFi Tuning gold and silver fuse, and the Furutech fuse.
They're really not that expensive looking at the prices that you've paid for your other audio related gear, so it might be worth your time to buy one of each and just see for yourself which one you like the best.
They remind me of the Oyaide outlets, the R1, GX and XXX, each have a slightly different sound.
Remember too that your system and your listening preference is not like anyone else, so it needs to be you who ultimately picks the one that you like the best.
