Audio Grade Fuses - Page 2

Fuse direction matters. The difference is usually discernable without trying to listen too hard.

When inserted the wrong way, the sound will usually be a bit flatter and softer. Imaging not as good. It can still sound OK, just not "right".

On fuses with directional arrows - you should still experiment. Unless you are a circuit designer or tech, you may not know the true direction of flow in the circuit. Some boards have been known to be marked incorrectly.

In testing marked fuses here, it's been determined that the fuse manufacturers are marking them correctly for directionality.

All right. I have an open mind. I avoid cable discussions like the plague since they always end up in flame wars.
Is there a scientific reason for this (a link would be nice since I am curious) or is this strictly for audiophile purposes? I am familiar with Isoclean and Russ Andrews.

You say you have done some testing. Measurements or listening tests? I'm not trying to dismiss your statement. I just can't even theorise why a fuse would be directional and would like to know more. I'm very familiar with the theories behind the directionality of cables and wire.

Yes, the fuses are directional. I have a couple and in the process getting another one. They also need to be broken in to bloom in sound. Currently warming up to the Hi-Fi Tuning sound. Switched the fuses again a few days ago. It doesn't help that there is an Oyaide R1 Beryllium in the wall, it makes the sound a little extra soft to me.

O.K. I have nothing against subjectivity, but this is a listening impression?
There is nothing specific about the geometry or design of the fuse (grain structure of the 1" piece of wire, different materials in each end cap, tapering wire gauge) that would indicate directionality?

As I stated in my previous post, I'm very familiar with the theories behind the directionality of cables and wire. Whether these can be measured or not, there is a geometry or composition of materials that would indicate the possibility of directionality.

I can understand that a better physical connection and better materials might make a better fuse, but I would like to know what the design theory is for a directional fuse. There's always a reason for directionality whether plausible or not. I can't rationally apply any of the ones I'm aware of to a fuse and would like to know what I'm missing.

You can take one for the team and always buy one to perform scientific research on. If you have an amp that can use a 3 amp fuse I can let borrow one to maybe satisfy your curiosity. They are directional and have their own sound signature. Can't tell you too much more info than you could find on the web. Haven't tried the Furutech or the Acme yet to see what the sound signature is. Will have another one this weekend.

Actually my amps do take 3A fuses. I'll do some web surfing, pick a couple of brands and try them (which may or may not include dissection).

Fuses

The Isoclean made a major improvement in the sound of my Zana Deux. It is certainly directional in that the sound is improved in one direction and worsened when installed the other direction. The good news is it is easy to listen to the fuse installed both ways and decide. The change in sound is not small.
I think it is worth a try.

So I got FURUTECH and this fuse rocks. put the music closer to you. Slapped it in during the Seattle meet.
Getting 3 Audio Grade fuses getting 3 different sounds.
Got the IsoClean 1st. Very musical, great sound.
The Hi-Fi tuning was next. Very laidback and soft.
Then there was the Furutech. Brought the music closer, amazing sound.
These sound so different. Can see all of them rocking different equipment. If my Rega Ear had a fuse I would slap a Hi-Fi tuning in so fast?

I just got that one too Gil. the sound has clearer and more focus.

Picked up another Furutech. 3.15 amp this time. I'm amazed how each different brand fuse has it own sound. Great stuff to add to your equipment. Have to find more fuses to try out. I know acme has some. Who else? Any Audio Grade Fuse suggestions will be appreciated.

Has your opinion stayed the same after burn-in? Are you recommending Furutech over Isoclean? Or are they just different?

I'm curious too.

Bout to order a fuse for my new Raptor but not sure if I'm going to go for the Hi Fi tuning (which I already have two of ... one in my Stello HP100 and one in my Havana DAC) ... but sort of curious about the Isocleans as well ...

perhaps a fuse rolling guide is in order ???

I can help with a fuse rolling guide. I know WittyTH has a Furutech for his Raptor. OK I have had a IsoClean for over a year. Very familiar with the sound. The Furutech is Rhodium and Cryo'd not Gold plated. IsoClean will not disappoint. Very nuetral and musical sounding.To me the Furutech sound is soft, not laid back. To me was more engaging and pronounced than the Isoclean. I am partial to the Rhodium sound. Have a power cable with Rhodium ends, Rhodium ends on my IC's and a Rhodium Fuse. Would have had a Rhodium IEC port on the Amp but that was on back order. Just have a Gold one. Also have an Oyaide R1 and that is Berylium. Got very cofortable with the soft sound.

I want the most sparkle in the highs. Which one do I want?
