Quantum Science Audio light blue fuse; $71, what a bargain!


I wanted to start a new thread about the more affordable versions of these fuses. I don’t doubt that the higher end versions are amazing, but most of us aren’t very likely to be able to hear them for ourselves. Fortunately, pretty much anyone who is serious about building a musically enjoyable and engaging system can get a good taste of what they’re all about.


I’ve had the light blue QSA fuses ($71) in my CD transport and DAC for over two weeks, now. They replaced SR blue fuses, at around twice the price, and easily bettered them. I am expecting one more light blue tomorrow, to replace an SR orange in my amp. I’ll give an update on that, once I get it installed and listen.


Meanwhile, here are a couple quotes from my posts on the other thread:


“What I am hearing is; voices & instruments are more solid and lifelike, with increased natural detail and sense of space, better dynamics, and a more relaxed overall sound.”


“Just got in a second light blue fuse for my DAC. So far, more of the same improvements I got in my CD transport. Very nice!😃 One thing I appreciate is the break in seems to be pretty quick, without any of the nasties you get with some other stuff. Pop it in, and you’ll hear improvements in short order, at least that’s been my experience.”


I am continuing to greatly enjoy what these fuses bring to my system, and am really looking forward to getting the last one in my amp.

Like I said in capitals below, get him come on here to back the outrageous claims you fusers make about what these fuses can do and the fallacy that they are directional in the AC mains line.



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 THESE FUSERS, 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)






And now captain "fuser" has made an appearance

1. Isn’t using the term "shill" to describe a fellow member akin to a personal attack?
No, I’m not using a members names, as allnoise does, I just use term shillers for all the mainline fusers here, that con the gullible.


Every manufacturer in the hobby marks up their products.
>1500% markup!!!!!! (10cent fuse to sell for >$150)


What gives, Georgie??
Biggest con job in audio history, that’s what, that needs to be stamped out!!!!!!!!




Not sure why when someone like georgefoofi who is on a self appointed crusade to harm a certain section of the industry is allowed to post his insults and vitriol.

Only to the snake oil AC fuse voodooist’s sunshine, that deserve it all, who have not one iota of electronic knowledge, just their own vitriol on AC fuses and what they can do for the sound.
Why would anyone who favors fuses have vitriol for it?

The word vitriol comes from the Latin word vitriolus, meaning "small glass". (perfect description of a fuse)
And then can also mean vitriolic, and so "causes a lot of distress and pain", to those gullible enough who have just spent $$$$$$ on a 10cent fuse.

Cheers George
Oh dear, another know-it-all
Yes and one look at your last page of posting history shows you are a "voodooist" that can only comment on "snake oil" products, without 1 iota of electronic knowledge to present to backup your comments.

Imagination is a wonderful thing!

So will "electronic knowledge" gullibility and stupidity, make them susceptible to this AC fuse snake oil **** ****

Nah! these last few riveting post are starting to resemble members of the magic circle club.   https://i.ytimg.com/vi/f16WrEdr9qM/hqdefault.jpg
As for personal attacks (going at someone personally), that’s what you do

Sorry, I attack the BS being preached about these $$$$ fuses. Not personally the ones saying it, BIG DIFFERENCE


But by all means, keep reposting the same old, boring, advice that no one here follows.
So long as it stops even just one member from getting ripped off by these "snake oil" companies it’s worth the effort.

Does georgie think if you turn your gear upside down, the fuses will fall out?

Every time you decide to have a go at me personally, you'll get this. That may make a non technical gullible potential $$$$$ fuse purchaser, think twice about purchasing after reading it I hope.

I took your advice and changed out all of my SR Orange fuses for fifty-cent Bussman fuses. The clarity went away.

yeah sure ya did🤦‍♂️
Quantum Science Audio and George working together to bring aftermarket fuses to the masses for a tweaked out good time.

Sorry sunshine no backsies for you, and no promoting of "snake oil" fuses from me.
You would have got the same result with a new 50c Bussman fuse, with as you said a clean and tighten of the fuse holder.
8:11am
Just clean and tighten your fuse holder and re-new your fuse

I just heeded that advice and now the QSA light blue fuse is out of this world! I thought they were good before but thanks to George these QSA fuses are absolutely incredible.

And there it is!!! (clean and tighten), if this non technical member did the same but with a new 50cent Bussman fuse the end result would have been the same. "absolutely incredible"

Like I said if your going to attack, do it against the proof posted on the topic, not personally yet again, as it seems that's all your good for.


Fuses measure differently in either direction

really!! You believe what the "snake oil company itself is telling you!!! And it’s milliohms!!!! (thousands!!! of an ohm!!!) are you serious!!!!!! That can be the difference in ambient temp reading from hour to hour. GET REAL!!!!!!!

If you really want to impress the doubters, show independent measured
technical reports on this, not what some fuse shiller is drip feeding you that you don’t understand
: every fuse discussion become a Georges one.
No every fuse discussion is ** and there no technical engineers that will backup that **. So I post the other side of the fence which shows what happens to fuses.

it just distracts from threads.
Na, it gives the other side of the fence view of this "snake oil" with some technical, answers not just voodoo sayings "trust me it sounds magnificent" .

Once again another great thread quickly ruined by the "fuse hater"!

Na sorry ya got that wrong, it’s one that’s exposing the "snake oilers" trying to make a huge profits on the gullible, selling them 10cent fuses for $150+


I don’t know what improvement they bring, but the name is a real turn off

It’s all a money making grab from the gullible that have no technical knowledge, by those that feed on their gullibility like leaches. Like a few other audio "snake oil" products

Like: These $20 little black dots you stick on the end of a fuse.

Come on guys, let’s give Georgie a break.
Don’t patronize me mate, you’re the ring leader for this AC fuse "snake oil" stuff.

This thread is about "snake oil" fuses, can't you guys support it with some/any! technical info to back up what you claim they can do??
Instead of trying to shift the topic to my product which has nothing whatsoever to do with fuses. ARE YOU THAT ******?


Thought you’d see it, you can’t argue with Electronic Engineering Laws and the measurements they give, with only voodoo and snake oil hearsay.


Little thing called measurements and EE laws answers all if you know any of them.

But continuing to carry on about it negatively without even trying one is disingenuous
No quite the opposite, it gives the non technical the technical views from the non voodoo side of the fence also, so they can make an informed choice.

Cheers George 

 
I decided to go and hear by myself. Bought a yellow for my preamp.


Should of just tried below first to save a bucket load of money

The fuse still heats.
bends and deteriorates with age.

Wrong, it’s the opposite, and shows lack of technical knowledge.
As fuses get their worst punishment at "switch on" that’s why they blow sometimes for no other reason than age.
It also shows the power supply is very large with good amount of "storage capacitance" to charge up, and that the amp could be very in class-A/B bias.
And last the amp could be tube which needs even more current at startup, because of the added heater factor surge at start up of tubes,
So proves that above statement totally wrong.

Never tried boutique fuses, or different directions on any cable or fuse

Don’t even entertain the thought, it’s a snake oil con, aimed at the electronically gullible

They have to be akin to a diode to be directional, but it’s a piece of wire.
Same goes for cable, and if they do act like a diode then that’s bad news.

Before I swap out all of my SR orange Fuses and Duplex boxes

Absolutely https://youtu.be/YTY26k0CA0I?t=4


I do see that the fuses show which direction they should go so that is good.
Like I said before, you can’t, the mains is AC (Alternating Current), it changes direction 60 x a second) so it’s impossible to put the fuse in the wrong way!🤦‍♂️🤦‍♂️🤦‍♂️
You just did, you called him allnoise, when you know his user name is nonoise.
Dam autocorrect, but if the shoe fits  

Mods!!!

This is starting to sound more and more like yet another "snake oil" fuse ad!
Selling 10cent fuses for a fortune, and ripping off the uneducated electronically gullible, that believe these shilling fusers **** ****.


You’ll get it closed like history shows you have others, by attacking personally instead of the subject on hand.

Like I said same old crew, with the odd new recruit with minimal posting history thrown in. (makes one wonder about them) 
Only the same old fuser shillers, trying to recruit more of gullible. 

You never see the great amps use DC rail fuses, it's just not the thing to do, you may as well have spring loaded speaker contacts for your speaker wire on the amp and the speakers.
Cheers George

Pity you lot don’t have the knowledge to know the difference when that circuit of mine is used as a series /shunt vs just a series as it was with the MkI Lightspeed back in 1980.

Here educate yourselves, if at all possible.

Wow, ouch just ouch!

Do your homework sunshine see if you can finally get it.
pauly
He makes a fantastic preamp and he’s not an irritating know-it-all


Advert.
There are no capacitors or resistors (other than the photocell) in the signal path.

Please with all that electronic knowledge of yours, what do you think that preamp is, and what it’s copied from??

I can’t help but wonder how many other potential customers have been deterred by it?
Sorry but I don’t care, especially if I found they are "fusers"🤦‍♂️, they would never get one no matter what, if I knew.🙄

I ask you why are there no! "noted electronic audio technicians", posting and confirming in these pages for what you "fusers" say these ac fuses can do to the sound???🤷‍♂️
Done too often you risk being seen as a crank at best or worse, a stubborn fool.

We wouldn’t want that now would we?

No no! one would never want to look like you, heaven forbid🙏
@georglofi you have been around awhile, do you not get tired of instantly pouncing on every fuse thread??? Very tiresome.

Only if "snake oilers" are promoting them for "snake oil" companies that secretly sponsor them with their products.
As a 10cent fuse given away to them is reaped in rewards if/when only one sale has to come in for $71 each.

And because even if you had one iota of electronic knowledge you’d know this ** needs to be stamped out of the industry
