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.
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 and get crusty as these pics show of a fuse ageing over time. https://ibb.co/9NbTwqK (even the $$$ boutique ones will age also) Cheers George |
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. As I said to those that are interested.

Love the way you just make things up. Shows a lack of maturity. Any decently designed piece of gear will account for current in rush during "switch on". There has been progress since the ’50s. Meanwhile, I’m continuing to enjoy listening to my gear with their HiFi Tuning Silver Star fuses, which have done journeyman service for the last 7 years. You've proved nothing wrong with my statements. That, and no one on this thread cares what you think. All the best, Nonoise |
As said no electronic engineering technical knowledge. As I said to those that are interested.

Nothing wrong with using good reasonable priced contact cleaner. Magnets are something else though, (voodoo comes to mind) As I said to those that are interested.

The fuse still heats.bends and deteriorates with age. As I said to those that are interested.

I've never understood closed minding thinking (those that only reflect on the past - flat earthers?) - after all, exploration and discovery is what makes technology better and our lives...I have found tweaks to significantly enhance my listening pleasure...without understanding 100% why they actually work... Any speculation on what QSA is doing with their fuses? Not that it really matters - as long as they sound great...but Graphene - perhaps? I mean SR, PPT and myriads of others are using it...there is certainly something going on here - I can hear the improvement when applied properly. From a Science article...substance perhaps? One of the biggest finds is that, using Weyl fermions, the researchers will be able to create fast-moving electrons with no risk of backscattering, or loss of electrons in a collision. Backscattering makes electronics less efficient and creates heat. Weyl electrons are able to avoid collisions and eliminate backscattering. Essentially, what this means is that the Weyl fermions could provide a better flow of electricity and assist in the creation of more powerful and efficient electronics, especially in computers. It's interesting as others have found purity of copper sounds better - and they have suggested that the improved lattice structure helps with flow...and sounds better...perhaps graphene. I am auditioning some new "gear" / "Tweaks" right now. But when this trial has passed, I will move on to these fuses and outlets... |
'life is too short to argue endlessly with strangers you couldn't care less about on internet' -- luke skywalkerI'm sorry jjss49, but that is historically inaccurate. Although commonly attributed to Luke Skywalker, in-depth archival research at Washington's Air & Space Museum shows that it was in fact first uttered by Orville Wright, the night before he forever changed history by inventing his brother Wilbur. |
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 As I said to those that are interested. Cheers George |
And you were showing such promise.....
+1 George, If you need to hate something in this life, I guess "boutique" fuses are an okay choice. But continuing to carry on about it negatively without even trying one is disingenuous at best. Do you think it would be right for someone to do that with one of your products? |
@thecarpathian no it was luke skywalker’s great great great grandma - amelia earhardt!!! side note -- one thing that i learned in this thread, is if you have to... like you HAVE TO... JUST HAVE TO have the last word... each time, every time, all the time that is how you get to 10,000 posts in a hurry on this goofy forum |

@ Glory - Tell me more about the what the fuse did for the Sorcer as I have the x4 and really like it. I demo'd it for my teenage nephew and he heard the difference immediately and said, "plug it back in, please" - I am also considering a fuse for my SR SE active ground block which has a orange fuse in it... |
Little thing called measurements and EE laws answers all if you know any of them. As I said to those that are interested. Cheers George |
The way he capitalizes Electronic Engineering Laws as if some audio Moses came down the mountain with those laws etched on CD is the strangest thing he’s posted since the last time he posted. There’s nothing in those Electronic Engineering Laws about fuses and how they can affect the sound of an amp or he’d cite it instead of bleating those three words, over and over and over and over. All the best, Nonoise |
Come on guys, let's give Georgie a break. Everyone knows that measurements will tell you exactly what you are hearing and that you cannot solely rely on your lyin' ears. @glory >>> How's that Red/Black fuse working out? Frank |
Just got my Light Blue QSA fuses. For sure, hard to imagine noticeable improvements with something as small and innocuous as a fuse. But Tweek Geek and users do not exaggerate! In a word: clarity. Voices and instruments jump off the record and demand attention. The performance of this little thing inspires me to return the Blue and order the Yellow. I have them in my mono blocks. I love this forum and look forward to it every day. It led me to my destination AGD amps, my Silversmith Fidelium speaker cables and now QSA fuses. |
Don’t patronize me mate, you’re the ring leader for this AC fuse "snake oil" stuff. And once again, just to give the "non technical" here a more technical view point from other side of the fence, instead of from the "snake oil" side. To those "non technical" members that are interested. Just clean and tighten your fuse holder and re-new your fuse (if old) with a good quality 50cent Bussman, Littlefuse or similar. Cheers George |
Hey, I thought I was the ring leader! Ever notice no matter how many times one asks george to cite just what and where it is in that Electrical Engineering Law book of his that a fuse doesn’t have an effect on the sound and all he does is recite what he, personally wrote, over and over and over again. No one is buying what you’re selling, george. All the best, Nonoise |
