Hi Fi Tuning fuses

Why would we put any stock or trust in the opinions of audio equipment manufactures like Roger Modjeski, Nelson Pass, Roger Sanders, or any of the rest of them. What do they know about audio or electronics, anyway?

I’m thinking, though - If you have many thousands of $$$ in audio gear and it just doesn’t sound spectacular, instead of investing thousands more in cables and fuses, just change the direction of the cables and fuses you already have. Problem solved......Jim

Kat a mite. 😻

You can’t tell by looking at them. You have to try them both ways, one at a time. One way will sound better than the other.

Newbie about fuses. 
I'm looking at my 4 HIFI Fuses to swap out with original fuses from my Statos stereo amp. How can you tell in which direction to install them correctly?

Most likely Kimber cables have arrows for some other reason than wire directionality. Maybe shielding direction, who knows? I never perceived Kimber as being at the forefront of Cable technology, but maybe that’s just me. What I do know is than many high end cable and electronics makers are at least two paradigm shifts behind the power curve. Fuses, wire directionality and power cords are excellent examples. It certainly appears they all either never got the memo, like yourself, or completely dismissed it as too much trouble to get involved with or else it’s just too late to change their ways. Mule metaphor.  Dog metaphor, Old dog, New tricks. 🐩

What! Whoa! Another direction person?! OMG! What’s that make now, 40,001? Well, shut my mouth and call me corn pone! 😛

I did put them down as recommended
But I did not change the directions
In order to hear that the result was better than 

But I ask a simple question
If the companies we pay them so much

They can not do this for us
Because a difference of $ 200 is really negligible to the price
Which costs $ 3500, for example

I have never turned to hearing if there are differences
Only if they are different from the original and there is a difference.
There are many other changes like polarity in electricity, and it changes certain equipment in the 90's

I felt it improved the dynamics in my Cary tube amp but only if installed in the proper direction! Placed the opposite way it degraded the SQ."
@three_easy_payments, I can't tell if you're being sarcastic or not.

@2channel8  yeah, I guess it could have been taken as sarcasm.  I was being serious.  Direction made a huge difference.

Hi, the direction of writing on cables (unless specifically recommended) or the direction of the diode symbol or name on HiFi Tuning fuses are not (rpt not) the key to the correct direction.

Yes, the direction was all in the same direction as the speaker cables. The fuses were also uniform
And this is a name imprinted on the fuse

🐈💩😷

Yes, given your proclivity for directionality, I thought you played for that team.

🙉🙈🙊😻

Cat a mite. 🥴

Yup. Yours, Joy Boy.

More like an .ss bangler. 

"that’s why I included ...... among the mossbacks"  @geoffkait , I haven't heard that term in ages! Brings back great memories. You must be a bass angler.

Question: did you evaluate each fuse one at a time for directionality? With so many fuses direction of fuses is critical.

I changed all 5 fuses
For all 5 power supply providers
At Marantz SA-11 S1
Exactly the same value
I did hear differences in width
 switch and hear right from the box  HIFI Tuning fuses

PART 1
The difference was, but not very significant, to say there was a change. As new
I returned the original I heard
I immediately changed
to new ones and there is a change AS IT WAS AS FOG ON OLD FUSE

PART 2
I put it on for a few days.NON STOP
And hearing ....comes back
I switched to the original I heard then with the HD800
And the BCL Leiman amplifier to HEAR  sound really differences

I stopped after   10 MINT  the original .

the audiophiles  HIFI Tuning fuses  played for a few days
The result is no doubt heard IN  HIFI Tuning fuses
A larger stage width
The depth of the stage is impressive and deep TON
And most importantly the height was more significant for example
Flutes that were heard earlier at 10  are now at 11 o'clock
The inner detail is greater
Each fuse goes to another significant part of SA 11 S1
On other devices, I did not make the change
 PART 3  4 WEEKS ON 
Well I put everything back to my original  FUSE and immediately heard that it was all without the same effect
I had in new fusions BACK  HIFI Tuning fuses TO MY SA-11 S1

its as simple as this....

If you have a type of system that will allow for it? Fuses will make a difference in what is heard. I have switched a few things around, and I was not be able to detect and fuse differences. That is why this debate never goes anywhere. Hearing it is totally system dependent.

Besides.. Not everyone desires to tweak their system to the point where these differences will be heard. They and find those talking about the benefits as a pain, because they are content with what they are hearing as is. To each his own.

Yes. Some in their system can hear differences. Others can care less and do not want to be bothered. They resist because they are happy with what they now hear and try to find reasons not to get curious. So, they will say someone who hears fuse differences is delusional to get the thought far from themselves. They simply do not want to be bothered. They do not desire the same thing from their audio system.

Those who hear fuse differences out to change out their power cords to regular ones and they may find they can not hear fuse changes.

@lalitk then I wouldn't have enough foil left to make my hat 🤣

The incident under discussion happened long long ago in a galaxy far far away. Too long ago to matter. Let’s move on. Frankly, I wouldn’t be terribly surprised if it wasn’t even true. Somebody’s got a bee in his bonnet 🐝 No big deal. Besides, gentle readers, even stock fuses have issues from time to time, you know, like blowing prematurely. 🔥 It’s not exactly a big secret. 🤫

The assertion: HIFI Tuning fuses are a danger, to the DC circuitry of tubed amps. The issue: Thus far, NO evidence/coroboration, outside of one(purported) incident/report. All I’ve heard from the Fuse Police, are deflections and cop-outs.  IF these fuses WERE a problem, someone else, somewhere out there, would certainly have noticed by now!

But did you blind test the cat food tuna?

You’re not a good example. Yeah, like Chuck Audio Mart. 🤗 Audiophiles want tuna that tastes good, not tuna with good taste. 🐬

Yes I’m sure us audiophiles are waaaay smarter than the amplifier designers🙄🙄

If frogs had wings they wouldn’t bump their a-- so much. If Judge Judy was 6’ 2’ she could have been a big basketball star. Woulda, shoulda, coulda! Amplifier designers are generally about two paradigm shifts behind audiophiles. Fuses is a perfect example.

Were they looking in the mirror? 

Great thread with links to a relevant study. Study shows those who buy into this nonsense tend to be of lower intelligence.

Why does that concept not apply to those who report these miraculous improvements with fuses and power cables?

@bdp24 - About that, "report": The concept is really quite simple/logical: You BROUGHT it up. Now, BACK it up!

I couldn't care less if the Hi Fi Tuning fuse: 1- does or doesn't provide better sound than Buss, Little Fuse, or any other garden variety brand; 2- does or doesn't possess the potential to make possible damage to an amp. I have no ambition to make the case for either 1 or 2, prove either, influence or change anyone's mind on the subject. I had no idea that simply to bring to the attention of tube amp owners the experience with the HFTF that Roger Modjeski reported would require, even obligate, me to defend, even prove, that report. Shows what I know!

Here comes the fuse police..........Those who have convinced themselves that the change to "audiophile" fuses and experienced audio improvements have probably exhausted all other methods to improve a system's performance. While not ready to admit shame of a wasteful purchase, it's normal to convince oneself that something good has happened. According to a common term.....psycoacoustics.
What really matters is that every human's perspective is different. Nobody can convince anyone else that what they hear is real or not. The purpose of fuses.....protection. Look further down the circuit chain to find possibilities of REAL results.

Great. Another dime store shrink.

All the best,

@bdp24 - As I’ve stated before, numerous times, IF that article is correct, WHERE’S THE EVIDENCE? That ONE incident can’t be the only one, CAN IT? You can take his word for it, but- I’ve personally been using HIFI Tuning fuses in my tubed amp, DC circuits, for better than 12 years now, without a problem, EXCEPT when the occasional tube went South, and the fuse DID IT’S JOB.  Far as I'm concerned, without corroboration, that article is, "rhetorical".

@1988eldorado,

Add some wads of almuinum foil in your ears too, your MC275 is going to sound as good as MC2301 😉

As much as I love the sound of my Kinki EX-M1, I went and experimented with a PADIS fuse since accessing it is so darn easy.
The fullness now that accompanies the extraordinary sound of the Kinki is most welcomed. 

All of that for $25. And they're PSE, UL and SEMKO rated and approved (meaning worldwide). I even went back to the standard fuse (a low cost ceramic type) and tried a Brimar fuse but the PADIS was the clear winner by a large margin.

I personally don't see what all the hubbub is about when it comes to fuses: they work.

All the best,
Nonoise

Every since I replaced the fuses in my McIntosh 275 with wads of aluminum foil the sound is much more betterer.

SR Black in my Perreaux R200i amp.
SR Red in my two Dacs.

Bargain prices for the improvements they provide.

One has to wonder when that strange incident with the HiFi Tuning fuse happened that RM constantly brings up on every audio website he can find. Was it 6 years ago? 8 years ago? 10 years ago? Is he obsessed. Are fancy fuses his White Whale? 🐋 Thar she blows! Shiver me timbers! Is RM the real fuse troll? OMG! Be that as it may Audio Circle is the perfect audience for his uh, point of view, as it were. Here, not so much. 😬

@rodman99999, the answer to your "why would a correctly valued fuse (in voltage, amperage, and time), as required by amps’ owner’s manual, be a danger to it’s DC circuitry?" question---a reasonable one, is exactly what Roger Modjeski (my "hero", according to Geoff ;-) provides in his writings on the subject of the Hi-Fi Tuning Fuse (brand name, not generic category). The Audiogon thread in which Modjeski discussed the fuse has been removed, but all one has to do to read what he has to say about it is go to the AudioCircle Music Reference Forum. Reading the related thread will provide the answer to your question; you will then never again need to ask it! If you aren’t willing to do that, I can only conclude the question was a rhetorical one.

Geoff the fuse troll is in rare form today folks. Are you listening to him yet?  That won't stop him.

Again(from the other fuse thread):  It seems, quite a few that frequent this site, value the opinions of the Stereophile Magazine writers. Personally, I would think, they’d be somewhat conscientious, as much as they value testing things, before recommending a product/tweak, in their reviews and follow-ups. ie: https://www.stereophile.com/content/hifi-tuning-fuses and https://www.stereophile.com/content/hifi-tuning-fuse-follow-may-2012 It appears, no one(as of 2012) told them, about all(ONE of) those amps(purportedly) being destroyed. I’d further have to think, that highly experienced sellers(ie: Music Direct, VH Audio, Parts Connexion, The Cable Company, etc), would have been made aware(by now), were there an issue, and avoided selling anyone's, "high-end" fuses(and any possible, attendant liabilities). There again: Just my own observations/opinions.
