Upgrading Fuses

All the manuals of my components warn against attempts at fiddling with the innards as there are no user-serviceable parts. How do I go about changing fuses?

As far as I know, not every equipment benefits highly from high quality fuses and that's what happened in my system to, however partially.

I bought one Furutech for my Cary 300B and it changed things in the good way. The sound become bit warmer/smoother and fuller, took some sharpness away. Another fuse, also from Furutech, was installed in my CD player, Unison Research Unico, but the results are doubtful, not bad or worse at all, but if I can hear even more difference than say from Cary upgrade only, not sure. I guess I have to install the original fuse back to hear that, but it never bother me, so, I just leave like it is.
Furutech fuses, as I have read, requires around 100 hours of burn in, but I found them to open up with first 5 hours already and indeed even better with longer use.

Even this is a simple wire, as some folks thinks, it still a wire and the power gets through it, just as through power cable, isn't? So, why power cables make that huge differences in some, or almost every, situation and fuse cant?

I don't see any other complain here than the high price only, but before you consider to buy expensive power cable, just try to roll the fuse first and you may save some cash for something else, who knows...

Enjoy the music

Cheers

Jtein,

Not all amps have fuses...Krell for example. I would not risk voiding a warranty for any reason. You should contact the manufacturer about this. It's critical that you replace fuses with the proper specifications required by the manufacturer to avoid damaging your equipment. If it's a large 10 amp slow blow then that is exactly what you need to use.

PS Audio has authorized the HiFi Tuning fuse upgrade for their gear and the company's CEO has blogged about the sonic benefits. It's a major reason why I tried the fuses....that and other user feedback. Hope this helps.

"Not all amps have fuses...Krell for example."

That's crazy talk. Must have a fuse, no? I've never heard of such a thing. For nothing else so that your house doesn't burn down.

Krell amps use no fuses. I believe so they don't impact the sound quality.
