McIntosh fuse changeout to make better sound


Have anyone change out the fuse in the back of a McIntosh integrate amp to make it sound better? Does this work or is this a myth? And if it does what kind of fuse? Thx

@jhills, I never claimed a startling difference and I’ve never advocated spending $147 on a fuse. What I have heard are more akin to tonal shifts, attenuated highs, an out of phase characteristic to the sound, etc. They were, however, significant enough that I kept on researching (something most audiophiles do) until I found the best fuse for my needs, never having to spend more than about $50 bucks per fuse.

And, again, if a fuse’s job is just to protect and has no effect on the sound, then some small speck or mote on the contacts wouldn’t have an effect on the sound. Either the fuse works or it fails, by design, and stops any current.

If that speck or mote has an effect on the sound, then a fuse with much better conductivity would, as well. Both ways argue better conductivity.

All I can and will say, from now on, is: until you try it for yourself, you’re arguing in bad faith.

Sorry guys, but who here honestly thinks that people are swapping out fuses as often as ICs or SCs. And, based on what you say, do you regularly go about opening up your gear and cleaning your fuse holders as often as you do your cable connections?

I tried that years ago when first told it was just the contacts and guess what? Cleaning them revealed nothing. No dirt. No residue. Nothing like what one would find on RCA and speaker connections.

I take a good look at those fuse holders when swapping fuses and they look brand new and nothing like RCA jacks and speaker connectors after 6 months, let alone 6+ years. I have to give you guys credit for imagination.

This is all nothing but going in circles with the same old tired arguments. What you great minds of audio should do is stop wasting time haunting audio forum boards and figure out just how and why a fuse can contribute to the sound, because it does.

Maybe with something made at the turn of last century would moving a fuse around inside its holder make a difference.  It would have to be poorly made, bordering on primitive. Never seen a fuse do what Georgie says with his summer vacation slide shows. 

All that supposed corrosion would be evident throughout the chassis and not just at one tiny point of contact where the fuse resides. Listen to yourselves. You're delusional and grasping at straws. 

Going one step further, how is it that a different fuse can't possibly contribute to the sound of an amp but just moving an existing fuse can, when all it's supposed to be is safety feature and not at all capable of affecting the sound? You can't have it both ways.

Someone should have bookmarked the passages where manufacturers use aftermarket fuses as it's been done. Holo May DAC is one.

Naysayers should read some of the European reviews of aftermarket fuses where some countries mandate fuses in the housing of the mains lines plugs. Of every one I've read that was for a TV, they all reported improved TV performance, which can actually be seen. It's along the same lines as what I've seen with better AC cords and power conditioning. 

That, and all the qualifying statements from those who've yet to try it makes one wonder, why bother debating, for they'll never know and will always complain, using the same, tired points.

And, it would be nice to see them stop using the medical analogy of placebo, since a placebo has no medicinal effect whatsoever when measured against a real drug and with any piece of audio gear, there actually is something of relative value and performance going up against what you're supposedly testing. In other words, they both work along the same lines for the intended purpose. One just happens to be better than the other. Leave the price of it out of the equation and they'll find themselves balancing on one leg.

All this reminds me of how my grandfather told me the way people get freckles. They spit chewing tobacco out the window of a moving car.

That, and I think I'm too old to be browbeaten any more. Too set in my ways, nowadays.

I did read your first comment and, sorry to hear that you couldn't hear an immediate difference. I did. Granted, with some changes I've had to wait for certain moments in music to verify what I believed all along, but it was always apparent on first listen that something was amiss, either for the worse, or the better.

The only time I couldn't, was when swapping out fuses on my Kinki EX-M1 integrated. Everything was more of a sideways move and in the end, I stuck with the stock fuse (which was anything but stock: it was a well made, high rupturing fuse that cost about $2.00, but much better made than the usual dreck out there).

Yes, confirmation bias is a thing and it’s proven every time someone says fuses can’t, and won’t, make a difference. They believe it so deeply that when they listen, they don’t hear any differences or write off any as of no consequence.

Oh, as for the Qanon reference, it applies to those who choose to live in an alternative world and not in the real world where one can hear the differences for themselves. Followers of Qanon refuse to think for themselves and choose, instead, to be led.

To be gullible is to think that everything that happens after the fuse's role is done is completely isolated and unaffected afterwards.
Is fuse directionality audibly discernible as well ?
It most certainly is.

I knew that swapping out bog standard fuses for better made ones made a difference but it wasn't until a year and a half after changing fuses and out of boredom, that I tried changing directions only to discover that it does make a difference. 

In my short fuse journey It tried it with various, mid level priced fuses and the results were all the same: it made a difference.

hotroady1,
Most certainly, since to be unknowledgeable is to not experience, first hand, something and then claim otherwise from an imagined higher ground, deluding oneself.

Sad to see that a self appointed liar who says Admin is watching those who use and advocates aftermarket fuses brags, again, about getting threads moved around as if that is what he thinks is winning, something.

This site is devoted to audiophiles and the sales of audio equipment and associated gear, with fuses, being a large part of that. Those fuses are made by the same makers of cables, power conditioners, etc. and again, account for a large share of sales here, which Admin is totally behind. 

I wonder if Admin is aware of what he's doing, discrediting one of the geese that lays a lot of golden eggs here, which is part of their revenue stream. Or, have they already figured him out and after doing the math, found out he is really of no consequence and just let him blather on?

These guys are dying on stage.
Deservedly.

Reminds me of the time I challenged others, like them, to go and start their own thread about fuses. It was quite some time ago. They did, and it lasted about a page and a half before it died of neglect. There was only so much back slapping, yukking it up, and reach arounds to go around before they grew tired of each other, having no one to argue with. Turns out it was a very small group and not at all representative of those who post here.

Trust the people who have tried an aftermarket fuse.
They work.
