FAST BLOW - meaning that if something happens the transformers won't be burned up.

Well I just listened to my system with the new HiFI tuning Supreme fuse, and I am impressed.

There is an increase in inner detail, more clarity and added depth and punch to the bass.

Sounds too good to be real?
Are you intrigued or a sceptic?

The cost may seem high compared to what the amp sells for,but this fuse made a bigger improvemnt in the sound than any of the tube swapping I've done so far.

If you are the type of person who likes to swap tubes, do some modding, or just likes to tinker, this fuse is for you.

Years ago I followed Peter Aczel and substituted the speaker protection fuses in an Amber amp as he suggested and in my pair of Mission 770 speakers at that time with solid copper wire(Romex with a bit of the insulation shaved from both ends,moddeled after a reg.fuse).

There was no going back.
I did this for every amp or speaker that had such protection and never blew any amps or drivers.

When the IsoCleans came out I tried them, and they were an improvemnt over stock fuses and offered the protection that my DIY fuses did not.

Now after trying the Supreme Hifi fuses, I can state that they are well worth the money they are asking.

Stereophile Mention of Supreme HiFi Fuses

I have been reading a lot about these as well. Granted, it's hard not to believe that tiny fuse elements won't affect the power your 5000 gauge power cord is delivering, but I'm still a skeptic on this one. But, if you and your wallet are in need of new territory, Music Direct has a good selection of the newer black ones.

for 50 bucks does the fuse have a lifetime guarentee like the amp does
