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.

I bought the HiFi Tuning Fuse - the $37.95 ones (basic ones, I assume). I just got them two days ago.
After only 30 hours, I am quite astounded at the improvements they afford my ASL Hurricanes and hence, the entire system.. I'd spoken to Tosh Goka, who said he didn't hear much difference. But having been a detective, I like to try things for myself.
Welll....they DO have to break in - at least a few hours. At first (meaning as soon as I turned the amps on) the changes I thought I could detect were very subtle, such as a cleaner, less glaring sound. That was clear but subtle and this was with almost no break in. Today a "Supreme" fuse arrived from Music Direct. Apparently, the Supreme version is similar in its construction to the Mundorf Silver/Gold capacitors. I wouldn't know.
I had the less expensive ones on both amps yesterday and, as I said, I DID hear a difference, but had to strain a little. After 24 hours, no strain is needed. The changes are obvious: transients have more leading edge, which enhances the sense of separation of individual instruments, and even the imaging improved (and Hurricanes do NOT need assistance in that category).

When I put in the Supreme on one amp I held my breath: I mean, who wants to experience disapointment. I wouldn't let myself expect much, but, by golly, they're changing by the hour. I would assume the first fuse, which had been going straight for 30 hours (left the amps on playing music) is ahead of its "Supreme" brother (or sister, if you will) in making the music sound like...music.
It also seems -- and I say seems -- to have increased the upper frequencies on the Hurricanes a bit, so that, instead of feeling like you're in a room with only 75 watt bulbs, it's now a room with 85 watt bulbs (which one could do with a rheostat in degrees).
I'm surprised you guys spend so much time doubting instead of doing the empirical thing, like getting one and putting it in your equipment and then playing the equipment for 48 hours straight. You'll hear it. I'll have to write Tosh and suggest he try it again.
The easiest thing to hear is the lessening of grain. And transients have less of a "burr" on them (e.g. violins drawn against the bows sound cleaner and sweeter than before the fuse change).
I put on the Leonard Bernstein recording of The Rites of Spring, an absolutely HORRIBLE recording - which is why I used it: anything that could make it sound better was either euphonic or just plain good - but either way, it would be an improvement, sonically speaking. Pre-fuses: Just a mishmash of instruments jammed together. Only the loudest instruments or the ones in front of the stage could be distinguished (on my system). But today, even though I had the "basic gold" ones on both amps, when I got up and well into the music room, I could tell the difference in the recording. It was starting to make sense, instead of the wall-of-sound it threw up prior to the fuse change. When I put the Supreme in, and played it again, it sounded...musical (well, as musical as the Rites of Spring can sound. Which isn't very, but it became entirely more listenable, meaning I was pulled into listening to the first 10 cuts before I stopped the CD.

Pre-fuse: I'd listen to one cut, and start jumping around to see if I wanted to listen to any other cuts. Just wasn't interested. Now, I find myself highly attentive.
Equipment:
First Sound Deluxe MK II, ASL Hurricanes, Hale Revelation 3s, Arcam FMJ23, Nordost Quattro Fil interconnects, Shunyata Andromeda speaker cable, Shunyata Python CX power cords, Quantum conditioner with QX4 units, Nordost Sort Kones (Brass under preamp, Ceramic under amps), Tube Traps Galore.
With the fuses in the system, it is very easy to hear when a change in the orientation of a tube trap is killing the sound. Of course, I could hear it before (my room has ASC's Wall Damp Treatment (resilient channel and squares of wall damps between two layers of drywall), but now it's so EASY to hear it.
I would rather someone contribute when they actually KNOW what they're talking about, then to simply post to prove Ivor Tiefenbrun's statement, "If you haven't hear it, you DON'T have an opinion."
You should just try it instead of making yourself feel superior for not falling for another "snake oil" get-his-money-before-he-knows-what-hit-him "scheme."
These actually work.
Sorry, I gotta go. I've been watching tv for an hour and I'm DYING to "hear" what else has improved!
Goodness Gracious, I done got me a case of the Vapors!!

It's only about 20 minutes since my last post, but I had to come out of the room, 'cuz those Hurricanes done heated it up something fierce and I just cain't turn 'em off. It done sounded too good! (And before anyone complains I'm un-pc, I'm a 62 year-old Black man and the way I'm feelin' right now, I couldn't care less that I'm coming across as giddy as Butterly McQueen!). G**damn!
So, lets make this easy. I have two fuses left, and I doubt I'll need 'em. Anyone who needs a 10 amp fuse (A Hurricane owner, maybe) can email me : mcbrion@aol.com. I'll GIVE you the fuse for free. That way, you can hear what I (and Lacee) can hear. I'll even pay the postage.
Just as a furthur note: between the time I left the room, an hour ago, and now, the separation of instruments has improved and I noticed, in particular, when the piccolo blows in Cut 2, 2:13 into the cut (the Mercury Living Presence CD of the Rites of Spring (Mercury 434 331-2), the metallic bite is there, but there's no ringing riding the harmonics: it's just a clean, clear take-your-head-off piping hot note! Usually, when I've heard it, there's an extra "zing" to it, but not this time.
So, even though it's only 1 fuse, if you use a 10 AMP fuse, post here or email me. First one wins.
I'm really thrilled that such a stupid little change could effect such a significant improvement in sound. It's not like I was looking for it. I just happened to be perusing Stereophile's articles and went thru the Powerline Accessories section and saw Fremer commenting on them. So I read it. It piqued my interest and I read it and ordered two fuses immediately. (it was only $75.00 for both plus shipping). Here's the link: read it for yourself. And I think we can assume Fremer, big mouth that he is (I'm one, too) is not shilling for ANYone.

So, just email me or post here. Whichever I see first, that's who I'm sending it to. This is just too good to keep it to myself. I'll check the threads and my mail for the next few days (today's December 31st at 12:20 a.m.)
May the fastest typist win!
No more calls! We have a WINNER!!!!
And I'll just ask the guy who I sent them to to post on this thread after he's had the fuse in about 24 hours. It should show some significant improvements by then unless the fuse (HiFi Tuning is the manufacturer, and it cost around $37.95) is oriented wrong. I'm not sure if only the top level (the "Supreme" model, which is built like the Mundorf, is directional, but I advised him that, if it didn't sound right to his ears, to turn the fuse (it has an arrow on the body) in the other direction and see if it makes a difference.
Frankly, I'd NEVER go back to the fuse supplied with my equipment. This fuse has made it so easy to differentiate between "fuzziness" that's on a recording and what may be the equipment ahead of it (I have it in the Hurricane amps, remember). Of course, my First Sound doesn't have a fuse in it: I called the designer, Emannuel Go, to ask if there was a fuse in the power supply and he replied there wasn't. (I was disappointed: these days, I want to put fuses in EVERYthing!). So, that eliminates having to open the power supply.
You really ought to try SOMEbody's fuse, guys. Even if it's a $10 model (I don't know who makes those, but that's not the point: the fuse DOES make a difference in the purity of the sound), you should hear SOME improvement over the .50 fuse that comes with the model.
There is a difference between the two camps.

One side, called the "believers" have actually used the "product" that is being discussed in his system and has drawn his conclusions.

The other side has not.
This side, the measurements types,who put their trust in the scientific method, don't even adhere to their own priciples.
They don't experiment and try the gear in question.
They refuse to do so.

Which I think makes them more of a "believer" than the ones who have actually expeience with the product.
Their beliefs are not based on the most fundamental tenant of scientific theory, and that is the experiment.

Where would we be today if everyone with a scientific leaning never bothered to try anything new.Refused to experiment.
No new scientific breakthroughs, no furthering of knowledge if one limits themselves to just living their lives based on what's already been done and blanket acceptance that there's nothing new under the sun, that we've been there done that.

This is what sets the two camps apart and it's ironic that the "believers" seem to be more scientific than the non believers.
They do the experiemnt and reach a conclusion.

Years ago I could have scoffed at what Aczel said.
But I didn't, I was curious, I made DIY fuses or bypassed the fuse.

I enjoyed better sound and never had any mishaps with gear.

Then when the upgraded fuses came out 20 or more years later I tried them.
It wasn't a belief or faith system that led me to them it was experience and that came from experience with what fuses do to the sound.Experience of twenty years of running without fuses.
I should add that I never left any gear on during my fuseless years 24/7.

Were the new boutique fuses better than bypassing or diy?
Perhaps not, but I sleep better at nite and my sound is not degraded by a cheap stock one buck fuse.

No the two sides have nothing in common least of all science.

Gbmcleod,

I *love * a guy who puts his money where his mouth is! Plus it's fun to see what happens. Thanks for doing this.
