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

I should get my 4 yellow fuses tomorrow ( Mono Amps, Pre-Amp and Lampi Pacific).  They will replace SR orange.  I have SR Orange Duplex boxes.  Question....for comparison purposes, would you put them in all of the components at the same time?  Or, start with one component?  If so, which component would you insert first.  

Lampi would be my first choice, that is one heck of a good DAC

willgolf >>>

I would go with one at a time just for the fun of it. 

Generally, I like to change one at a time, front end components first, but you could start with whichever fuse is the most convenient to change. Obviously, you would want to do both amps at the same time. It’s always possible that you could like the effect in one component, but not another.

Does anyone know if this company makes their own fuses or just modify an existing manufacturers fuse?

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 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)

Cheers George

What's that noise in the background?

tommylion


et al., still waiting for you guys to cite musical passages and songs, where these Fuses make an audible difference.

Happy Listening!

Oh didn't you hear, that's right you can't, here it is again just for you.

@grannyring,

Do all three if you can! If you can’t, start with the mains AC fuse as MC said.

Instead of buying 3 light blue fuses for my Clayton amp, I’ve been contemplating on buying just one yellow fuse at a time. As like so many of us I probably would want to upgrade to yellow anyway.

On the Clayton S40 which one of the 3 fuse slots on the back of the of the amp is the fuse for the AC mains? Looking from the back, of course.

Do you think you may try putting 1 of the stones on your Puritan Conditioner? Thanks

I took out my stock fuses and painted them light blue.

AMAAAZING sound quality improvement.
I'm over the moon.
The light blue paint cost $3.95.  It is a bright light blue, about Gulf tone.
If you send me $20, I will mail you the rest of the can.

Haha, great find!

Tyray, the fuse closest to the IEC is the AC fuse.  It should also be marked 5A AC fuse. 

I had a dream last night that all of the A'gon naysayers came over for a listening session. It was quite a crowd. Instead of listening to music, they all sat around discussing equations and slew rates. I  had to leave the room for a moment and when I came back they were all gone ... and they stole all of my records. My very first thought was ... what in the hell are they going to do with the records??

@oregonpapa sounds more like a nightmare!

I’ve had the purple fuse in my dac for almost 48 hrs now and the improvement over the yellow is quite noticeable and welcomed. With each step from the blue to yellow and now the purple (light violet) the amount of musicality keeps increasing and I sit for quite a while being sucked in and engaged to the beautiful presentation these fuses seem to allow to take place.
Songs that I’m familiar with are taking on a new personality so to speak. I don’t know if it’s more information that’s being allowed to come through or just the lack of noise and grunge that is somehow getting purged by whatever treatment QSA is putting on these fuses. Whatever it is it’s producing the most enjoyable sound I can ever remember hearing and I’m already wanting to see how can I get a Red fuse.                                                          
One particular song starts out with an acoustic guitar getting plucked and after installing each color the sound not only gets more detailed and vivid but after the purple I could almost see the instrument and it’s size. These fuses are very different from the SR’s and AM’s I’ve had before. They impart such a natural and enticing sound that it really does feel like a huge amp or speaker upgrade. After hearing the yellow it’s hard to go back to the blue and now after hearing the purple it’s hard to switch back to the yellow. If all I ever heard was yellow across my components I’d be very happy but the purple is making me wonder what’s possible with the red fuse and more of the stones that tommylion has accumulated. Mike at Tweek Geek told me he thinks the jump from purple to red is more stunning than from yellow to purple, I’d like to find that out for myself...

This thread reminds us of just how little we know about audio gear and their potential! It also reminds us of how much more there is to learn. I can just image how great systems will sound in another 10-20 years.  
These fuses offer important SQ improvements helping us get so much more out of our systems.  SR has some work to do to match or surpass these new QSA fuses. I bet they manage to improve their product line as they fight to stay competitive.  I am sure they are still selling many fuses, but over time QSA will expand in audiophile awareness and sales. 

The SQ effect of the light blue fuses in my mono blocks is stunning!
It is different and unique from other upgrades. The overall presentation of the performance has jumped up to just be more palpable. That is, you can reach out and touch it.
But I will limit my fuse upgrade to the $211 each yellow.
#1-the light blue are already spectacular. #2-it should be “mellow yellow”.
Mike says that he expects more stones and fuses next week.
I am waiting on yellow fuses and red stones.
Since the fuses are so excellent, there must also be something to the stones. It has been said that the stones bring the Bybee V2s to the next level. Anyone have experience with the V2s and stones?

Do you think the video I attached to his quote will pacify him?

It did answer all his statements about manufacturers engineers and actual use in production units..
the silence will be welcome to this thread, and lets talk about the topic originally started.

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.

Sorry, but no, not in the least. I posted that very same video link over a year ago in another thread on fuses and he dismissed it outright without a valid reason.

He then went on about how Ted Denny should show up on A'gon and back up his claims. Well, Ted did and george ran away. Ted even went to the threads where george was posting and george just ignored him. I pointed it out to george and his explanation never made sense, and he kept knocking fuses.

Trolling fuse threads is george's hobby horse. You'd think Admin would do something about it. Maybe more people should complain about him.

All the best,

See what I mean? He’s just taken to copying and pasting the same thing over and over. It doesn’t take much to envision him sitting at his computer, waiting to pounce and post more annoying inanities, thinking it will wear people down and discourage them from enjoying a thread on what they know works.

He’s to the point now where he simply won’t deal with his actions of the recent past and his irrational behavior.
If you think he's unbearable here, check out his tantrums over on the Amps section dealing with Class D amps. He's insulting and abusive there as well.

Perhaps more to topic, at least as a preventative measure>>> whatever you decide to use for a fuse may be your business. If and when I do such a thing, I don't skip the step to lightly coat the fuse endcaps with De0x. I believe that some of the improvements that others claim to hear could just as well be a matter of making a new clean connection. It is not as much of a concern as say other connections in a system such as the very low voltage connections made by interconnects or phono cables, but if you decide to do something like this at least give it the chance of the best connection that it can make.

Like I said get anyone that’s a known audio technical guru to come on here to back the outrageous claims you few fusers make about what these fuses can do, and especially the fallacy that they sound different in direction in the AC mains line.

Further evaluations on the Yellow Fuse vs the SR Orange fuse:

A friend, a very experienced listener, record collector, and audiophile came over this morning. We spent the time doing A/B comparisons. It is very easy and quick to do on the ARC REF-3 line stage. Here’s what we came up with:

New Yellow Fuse: Much deeper and more articulate bass. Purer highs, more overall clarity, and faster. There is a more well-defined front-to-back and side-to-side soundstage. Quite remarkable, indeed.

The SR Orange fuse: So far it loses out on all of the above areas, BUT .. it has a more liquid midrange. It is more tube-like in a very good way. From a musically involving standpoint, the SR Orange fuse still wins the day.

At this point, both fuses have their strengths. Ultimately, I’m hoping that things will improve with the Yellow fuse’s midrange as it breaks in more, as I’m only about ten hours in on it. If it can eventually match the beautiful midrange of the SR Orange fuses, then indeed, we have a true Allstar.

I recall, the SR Orange fuses needed about 50 hours of break-in to sound their best.

All of this is system-dependent of course. In the meantime, I’ll be holding off on my second Yellow fuse purchase until the current one is fully broken in.

Stay tuned ...

Frank

PS: The Orange fuse has been treated with PPT Total Contact, and the Yellow fuse has not.

I believe that some of the improvements that others claim to hear could just as well be a matter of making a new clean connection.

So correct

The Blue in my Blackhawk is awesome. The very best components improve detail and dynamics while also somehow managing to be more liquid smooth. The Blue does this better than any component or tweak I have ever heard. It was good right out of the box, and now is so good it is like its not even there. By which I mean zero artifacts or evidence it is doing anything. Everything just sounds so much more real and "there". Thinking of using their 90 day option to upgrade to Violet, and maybe Yellow in the Herron.

I wish I could easily change the fuses in my Rowland Monoblocks but the chassis's are 1 solid, milled aluminum billet. Only authorized dealers/Jeff Rowland can get into the chassis's...
