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.

: 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.

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.
AND YOU WON"T SEE THEM ON THREADS LIKE THIS AGREEING WITH WHAT THESE FUSERS ARE SHILLING
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


Georgie,
Please read and try try real hard to comprehend with an open mind...
Fuses measure differently in either direction that is why they sound different in orientation, 60hz can see resistance.

Also Paul has been around and building equipment for decades Listen to his comments....

And
This quote says it all, to bad these close minded people continue to pollute the community and ad Nothing positive.. this is why the world is like it is now days.
“Less harmless are those audio enthusiasts who are least secure: those whose toxic rage at a world that does not accept the authority of their opinions—a world that persists in enjoying recorded music in ways of which they do not approve—accomplishes nothing other than making our hobby seem repellent.”

--Art Dudley

Also if you have not tried or listened to any of the other fuses out there You do not have an OPINION, if your so smart you should understand this?
Or maybe not .

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
