Upgrading Fuses


Have a Audio Research Ref 3 and am considering upgrading the fuses but I am a little skeptical. Would like to hear from people who have try this. Hard to believe that fuses can make a substantial difference like the manufacturers claim. All advice appreciated.

They work, but it will depend on the resolution of your system to determine just how big an improvement you'll experience. Expect to be disappointed for the first few days as they, like anything, need some time to break in. I kept my system on for 4 straight days at a very low setting and from time to time would check in on it.
It went from 'what the hell is going on here' to 'that's very nice indeed'.
I think they are selling mass production fuses...

Maybe with some makes but the HiFi Tuning fuses I use are made of ceramic instead of glass, to control resonance, use silver wire, and are cryo'd. It's not snake oil.
There are enough reviews out there from 6moons, PFO, Stereophile, and Stereo Times, to name a few, that think very highly of them, not to mention enough testimonials from us average Joes (and Janes) to start a blog.
Check out the other threads on this and go with a reputable make and you won't go wrong.
Jeff_Jones,

Point taken. But there are companies that did their homework and there are those that simply jumped on the bandwagon, diluting the process.
And yes, there will be glowing testimonials from those that want to hear and then there are those that did hear a difference. Mine sounded simply horrible for the first few days. There was no getting used to the sound as it simply sucked. But it changed, dramatically, for the better. I didn't think a fuse could have that much effect. YMMV.
In the end, 'if you are inclined to try it and it is cheap then what the heck' does apply.
How can a power cord make a difference?
It does.
How can interconnects make a difference?
They do.
I don't mean to be snide but this have been discussed to death already. Some of us hear big differences that we can't put into words, but they are there. Maybe its just a matter of being better built: that justification seems to apply to all things audio. Or it could be that there is something else at play here. I've replaced fuses on circuit boards that gave bigger results than the one I replaced on the slide out on the IEC jack but there were still improvements.
I simply can't explain why I hear a difference but I do.
I remember reading this article a long time ago and it still makes me smile.
The first reason: I bought it whole hog. Every word.
The second reason: He wasn't always right.

There is another thread somewhere, here, that addressed the issue of a switch box and it was pointed out the variances it introduces making it unreliable for 'proper' A/B switching. It can't be done reliably. Whether the poster was correct or not, I can't say, but Aczel doesn't necessarily have the last word on this as I don't remember what he wrote being on a stone tablet.

I'l stick to my own, lying eyes (ears) every time.
I couldn't find info, other than reviews that state that HIFi Tuning Fuses are made in Germany. I did find this but it is way over my head:

Hope it helps some.
