In Reply to: RE: So these upgraded FURUTECH fuses.... posted by Audiolover718 on May 10, 2011 at 11:57:10
Ceramic fuses do sound better than glass bodied fuses in many cases, but not close to the Furutech fuses which are the best Ive heard. Ive tried many types of generic ceramic (cryoed and not) and all of the Hifi tuning types.Only negatives of the Furutechs are they are slightly underrated amperage wise (or are they not overrated?) and can blow with initial current in rush on some equipment. They do sound great immediately but there is a metallic lower treble which evaporates with 500+ hours of burn-in.
I think the Furutech's audible character is the copper filament.
I am also interested in a lower cost substitute and will look into these AMR fuses that someone else mentioned and the PS Audio fuses which appear to have similar materials and construction as the Furutech.PSAudio Critical Link Fuses

Padis makes fuses that look identical to me to furutech fuses, it's said that the only difference is the cryo treatment, they're about half the price.
I found using avm paint on furutech/padis fuses make for a noticable upgrade.
While we are on the subject of fuses.....
I gotta say ladies and gentlemen, it would behove you to at least CLEAN your fuses. Even if they LOOK clean! I just did the fuses on the outputs of my MC 7000MKII line conditioner. It has never been done and the unit has some years on it.
I cannot believe the difference. I used some CRC electrical contact cleaner and did the inside contact of the machine, the fuse and the cap. Even though the fuses looked clean at first glance, once can easily tell the difference of a clean one when placed next to a "dirty" one. The new fuse shines with a jewel like quality that the precleaned fuse simply does not. The results are startling. Every possible attribute of the music has improved. Every descriptive applies to this tweak.
My Q-tip did not get nasty, but it did get a little discolored from the film that was on the fuses and holders. Basically, the same attributes of the polished fuse became the same attributes to the sound. The sound was "polished" I can hear the room much more easily on recordings. I have to use the veil analogy. You don't even realize you have a veil until it is lifted. Easily one of the best free tweaks. DO IT!
Everytime I have the interconnects off for some reason, I clean the innards out with a Q-tip (with most of the fluff removed) always a bit of tanish remived. Even from those gold connectors.
Cleaning your fuses will get you at least halfway to where a "superfuse" will. And don't neglect the fuse holder. I'm a big fan of HiFi Tuning fuses but it sure doesn't hurt to start with the cleaning regimen on existing fuses.
I'm with Dave on that, you have to clean the holder or why bother cleaning the fuse .........
Agree and don't stop at just cleaning. Bend the fuse holders legs in so they exert more force holding in the fuse. Also consider using a contact enhancer like quicksilver gold. Then with the 20mm x 5mm fuses use a small bit of heat shrink around the holder and fuse so it grips the holder even more forcibly against the fuse. All of his has as much of an effect as going from glass bodied to ceramic fuses.
