An update after yellow fuse in Lampi Pacific for 30 hours.  Definitely can hear a difference.  The tonality is more pronounced and I am hearing more detail even at lower volume levels.  Tomorrow I add the yellow to my Pre-amp followed by my mono's on Friday.

Go to a forum where the heavy hitters of this audio industry are, like Nelson Pass John Curl etc etc etc at diyaudio.com and see what happens to fusers over there.
Yup, I've seen that and been there.  These types of forums are primarily engineers which mostly have the mentality "if you can't measure it, it doesn't exist".  Such an old argument, both in that forum and this forum where people just fail to realize that this is a limited way of thinking.



Really, you know more than those guys

Like Nelson Pass John Curl etc etc etc at diyaudio.com
See what happens to you over there with your fuser spiel, you got it soft here with the like of me and others.
History is littered with “experts” who said “That’s impossible, can't be done!”…until someone did.
One of the dominant personality traits of engineers is their fear of criticism. As long as we continue telling Georgie that he's wrong, he will continue coming back in an effort to prove that he's right. 

Georgie ... You're right. These fuses are no better than stock fuses. In spite of what our lying ears have been telling us, there is no benefit to them at all. They are nothing but a ruse. Now go away and play with the Emus and the Roos.

I guess there is no difference in capacitors or resistors either as long as they measure the same no difference. John curl might have something to say about that.
Hiding behind names because one has no argument is a tell, if there ever was one.
This just in: http://v2.stereotimes.com/post/quantum-science-audio-series-purple-fuses/
It's a follow up to the original review of the Quantum Science Audio fuse review by other members, one who admits he didn't believe in it until he was sent the fuses to hear them for himself.

All the best,

Thank You for posting the follow up link. I enjoy reading Clement Perry 's writings. 

Happy Listening!


You guys can't leave it alone, 24hrs and still trying to jag a bites?? Keep it up, in the meantime catch this for your time and effort!

A fuse:
1: two end caps
2: short piece of fuse wire connecting the two end caps through a glass tube (that’s all she wrote).

To those "non technical" members that are interested, do not listen to fusers, listen to the techs of this industry that design the audio products you have.
AND YOU WON"T SEE THEM ON THREADS LIKE THIS AGREEING WITH FUSERS ABOUT THE SOUND IMPROVMENT DETAILS AND AC FUSE PLACEMENT DIRECTION, EVER!!!
Just clean and tighten your fuse holder and re-new your fuse (if old) with a good quality 50cent Bussman, Littlefuse or similar.
As with "many switch-on surges" they do deteriorate, bend, stretch and get crusty with electrolysis formations on their fusible wire elements before they give out, as these pics show of a fuse wire element ageing over time show. https://ibb.co/9NbTwqK
(even the $$$ boutique ones will age just as much also)
Cheers to those "non fusers" George


The only place a fuse has an audible effect is if it is placed in series on one of the + or - conductors of speaker wire. It will increase resistance and decrease damping factor. A bad way to protect a speaker from excessive voltage!


+1
Also goes in a smaller way for DC rail fuses in some not so hiend amps.

Cheers George
Please do not make this thread about George. He clearly has a personal vendetta against products and posters he disagrees with. His purpose in posting is to stir up controversy, draw people into fights and get threads shut down. His clear mission is to suppress open discussion of topics that offend him. I do not understand why he is allowed to continue with this kind of behavior, but it is what it is. Engaging with him, however outrageous, provocative and hate-filled his posts are, Will only help him in his twisted crusade.
Are audio fuses directional?

A: Yes, fuses are directional. Electricity should flow from the left to the right when you view the fuse. If you do not know the direction of flow you should listen to the fuse inserted in both directions. One direction will sound more detailed.

Does fuse affect sound quality?
What I mean is lower energy signals will be impeded more by this higher impedance state of the fuse on those bass notes that "pulsate" the fuse. So, yes, anything in line with the signal can affect the signal or sound. This pulsation is also not linear, so that also can affect the sound. I repeat Fuses do make a difference and "are directional"

If you have not listened to fuses you do NOT have an opinion..

Be nice and go away!
Bye Bye ;-)
The Yellow fuse is phenomenal. The improved bass extension on its own is worth the price of the fuse.


@oregonpapa what did you think of the midrange now, as compared to the SR Orange?
"The theory, wraps all these errors and fallacies and clothes them in magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king. Its exponents are very brilliant men, but they are metaphysicists rather than scientists. Not a single one of the relativity propositions has been proved. " 


"I hold that space cannot be curved, for the simple reason that it can have no properties. It might as well be said that God has properties. He has not, but only attributes and these are of our own making. Of properties we can only speak when dealing with matter filling the space. To say that in the presence of large bodies space becomes curved is equivalent to stating that something can act upon nothing. I, for one, refuse to subscribe to such a view."

This is, of course, Tesla refuting Einstein's theories.  He couldn't "get his head around" Einstein's work and made a number of strong statements regarding it.  Possible to be very intelligent and very wrong sometimes!

Guys, after extensive break-in...and yes, it was really "wonky" along the way and it took way longer than I thought it would for a "simple" fuse...but I have gone ahead and kept the "red" fuse for my Sorcer x4. I would say the break in was ~30 days? Not exact on this one, sorry. I did hold off on my assessment because the break in was again, wonky - bright, dark, etc...and kind of fluctuated...took a while to really settle in. 

Basically, I hear more air, bigger soundstage, more depth for sure, more detail, but also more relaxed at the same time - more musical. Interestingly, some of my recordings are "more" listenable, more musical. They were good before, but now are more enjoyable. 

I did not use any paste as I wanted to "hear" the fuse and the fuse alone...I may experiment with paste later on, but I like what I am hearing now. 

Based on this I would recommend a demo and let your ears and wallet decide.

  • what did you think of the midrange now, as compared to the SR Orange?
I'm having a hard time wrapping my head around just how good this fuse is. As it has continued breaking in, the midrange is coming into its own very nicely. There is a concrete realism that was not there before. The human voice is amazing. 

While the SR Orange fuse was the benchmark in all of the fuses I've tried over the years, the QSA Yellow fuse has it beat hands down. No contest. How one little fuse can make such a significant improvement is way beyond me.

When paying $213 for a fuse, which to most, seems like a ridiculous sum, one has to measure the cost by the results. I've used ICs and PCs costing ten times as much that haven't given the results this little yellow bugger is giving. 

At this point, I'm thinking that other fuse manufacturers will have to go back to the drawing board in order to stay competitive.

That's honest to God's truth. In fact, I'm ordering another one that will go into the ARC-REF 75se. 

Frank
Pleased the QSA thread is open up again.
Sure wish people with experience with the fuses and stones would contribute more. Being so incredibly impressed with the light blue fuses, I ordered yellow fuses and red stones.
Curious about the stones? Going to try placing them on the power supply of my preamp.
Curious about Total Contact or 1260 Enhancer?
Curious about the Bybee V2?

jasonbourne52,  This is exactly where I found out about fuses and their effect on speaker SQ. I am still a BIG fan of the old Infinity RS and IRS series speaker..

I'm going to add dampening through a passive XO is NO dampening AT ALL.  ADD a fuse or four (4) and they takes the brunt of that type of fuse arrangement.

None the less if you don't bypass the fuses circuit or keep it in VERY good condition along with all the LPads.. SQ is the first to suffer. The first time was QLS1s the second was RSIIbs in the 80s.

NOW add a 1 ohm load in the mix like the Kappa 9.0 or 8.0 series and you have a disaster because of a FUSE and ZERO dampening to boot because the drivers are NOT direct coupled to the bass amp.

George understands how an amp works VERY well and so do you, it seems. My question is why not try a fuse in the sound path and see if it makes a difference. 

IF you read some of the CRAP I post, you'll see I had much better luck using "The Fuse" in the path and  less of an effect in the PS AC path especially with amps LIKE, First Watt, Pass, Mcintosh, etc. BUT in a NP design with fuses on the other side of the AC PS, fancy fuses not only made a difference, in some cases it lead me to BYPASS the fuse circuit all together..

Carys V12R is an exception to the rule. I use a great AC power cable and a blue SR fuse (from an ACME gold) with great success. BUT I really didn't notice the BIG change until I change the fuses on the other side of the power supply. The V12 has THREE. The same way with the NP design had 2-4 depends on the design..

I'm not saying spend the big money, I'm saying that in quit a few situations IF the fuse is put in the path between good parts (Power supply to amp rail), WHY would you want to feed the amp module with the cheapest piece of lead/tin/aluminum/whatever you could find. Much like a  standard Busman fuse.

On either side of that fuse holder is GREAT copper, silver or silver clad wire. It's not a bottleneck at all, it's straight up a fuse with TONE control.. :-)

Mechanically I can explain my position, technically, I may lack the understanding of WHY, but I do know where to look for the greatest improvement in spite of the COST of a product..

Regards
I’m still loving what 6 stones (2 red, 2 blue, 2 clear) are doing on top of my power conditioner. Clear improvements across the board; transparency, detail, naturalness, dynamics, PRAT, you name it.

Has anyone tried any of the QSA outlets?
oregonpapa-

That is quite the statement, knowing as I do your standard for "good". But even knowing that as I do, I would have to agree. And I haven't even heard Yellow yet, but only the light blue one. Just spectacular, head-shaking good stuff. I'm even thinking of trading my blue in towards a yellow, and also maybe a violet. You only live once, right? (That we remember, anyway.)
Monk’s Dream by The Thelonious Monk Quartet is sounding really good this morning. The improvements in PRAT with the QSA stones are especially noticeable on this album.
I'm a little late to this party, but I can attest that adding 2 SR Orange fuses (1 to my preamp, and 1 to my amp) literally left my jaw hanging open.

So, I don't really care HOW or WHY it works, but I know for SURE that it indeed works.

I have questioned which way to point the fuse.  I have 4 yellows in my system.  I questioned Mike from TG's and this is his response...

"It depends on the orientation of the iec input on the back of the component. if the iec input is oriented so that the center contact is below the contacts on the left and right, then the hot is on the right side, and the arrow should point to the left.  If the center contact is above the left and right contacts, then the fuse should point to the right".

I hope this helps others as it provided clarity to me and now I don't need to mess around.  In conjunction with the Townshend Podiums and the yellow fuses the music is sounding pretty damn good.  Next for me is I just ordered 16 Western Electric 300B tubes for my amps.  

Hope all have a good weekend.

Blind Will
Great info. I've ordered the yellow for my preamp. This will be my first ever fuse upgrade and the directional rules had me a little confused. Thanks willgolf.
@middlemass,

Sometimes it takes a little courage asking the questions you want cause no one wants to look 'stupid' to others. And asking that question, couldn't be more farther from the truth. So if you don't ask...You won't know.

@georgehifi, doing research on fuses about 3 years ago I stumbled upon this 2017 you tube video by Paul McGowan the chief electrical engineer of PS Audio about 'Audiophile fuses'. He didn't believe that something as small as a fuse could effect sound quality either.

https://www.youtube.com/watch?v=kFlnQ1chBno

Well, he does now, in fact he has completely changed the design of his products to make them more fuse swapping friendly.

Don't believe me, go to his PS Audio blog and you will see years of PS Audio customers sharing their stories on fuse swapping.

I got 2 light blue on the way and within ninety days - a hell of a long grace period, I'll probably get a yellow, and then...

  


If you have an amp that needed 2 or even 3 fuses and you decided to use 2 or 3 light blue fuses, a full complement, would you get better or worse sound from the amp using only 1 yellow at the proper direction at the proper location closet to the IEC inlet on the amp?

Ask Paul McGowan to come on here to back what you lot say about the sound quality improvements and especially the ac fuse directionality you fuser claim, then there will be some substance in what you lot say, if he does I’ll be the 1st to give it away.
He also backed MQA at first and bought into it!!!!, and now put’s **** on it because he looked silly for backing it at first, now that the odds are against MQA for being what they say it can do.
Same will happen with the fuses, he’s goes where the $$$$$ are, and you can take that to the bank..

Cheers to those "non fusers" or the gullible thinking about it George



Let me get this straight. I specifically give you 1 video of Paul McGowan videos about fuses, coming directly from his mouth.

Paul McGowan the chief electrical engineer and CEO of PS Audio completely revamps his fabrication process to make his ENTIRE line fuse friendly and you still don't believe?  

Ok, no problem. So why do you even take time out of your life to even post here? Is it that your only interest is to get 10,0000 posts?

Just saying.
Hey! he did go overboard with MQA too, and then backed out when it was proved a hoax. It’s all about the $$$$.

And you’re the one who bought me back into this fuse BS
+1 @jetter....are people uping the ratings, or using the stock recommendations?
Hey there Q Anonaudiophiles. What about the effect of 5G on your system? I wonder which SR fuse tackles that problem…

Tim Mrock was ahead of his time. His stuff was and is awesome. But nobody keeps great stuff like that secret for long. Lots of people are on to it now. NPS1260, what do you think that is? SR fuses and outlets, the glob of gray goop they tell you not to remove, what do you think that is? I'll give you a hint, the top end QSA Red and Black fuse uses so much they had to stick a piece on the side.

Millercarbon are you saying the key to these fuses is amount of 'special secret sauce' contact enhancer applied?

I always thought SR and new guys like this Quantum were using some kind of voltage conditioning process on the fuses, and the fuse price/level was just the amount of time that fuse spent on the conditioning device.

But if the key is contact enhancer, then it becomes easier for DIY to replicate.
tyray & others,

Please don’t argue with, or try to convince, George on this thread. He is completely close minded, and it will only aid him in his avowed purpose, which is shutting down threads like this.

"voltage conditioning process" ??????


Wouldn't surprise me if Synergistic Research and  Quantum Science Audio, are one in the same, now that SR has fallen from favor and Quantum is the new cheaper snake oil fuser on the block.

All that the members need to know that are thinking of buying into this fuse snake oil is

A fuse:
1: two end caps
2: short piece of fuse wire connecting the two end caps through a glass tube (that’s all she wrote). 

I ask what can be done to that 10mm of fuse wire, by these companies that have no technical credibility at all

George, have you actually tried any "audiophile" fuses?

Any at all?

Guess your ears can’t hear what mine do.

Really "jaw hanging open", you must be the latest fueser shill recruit




It is always the same.... again and again. You let one person be center of the discussion...
Just boring
And it‘s always the same person. Stoically cyberstalking all wayward fusers into eventual submission, salvation and redemption.
