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.

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.


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 use.
AND YOU DEFINATELY WON"T SEE THEM ON THREADS LIKE THIS AGREEING WITH THESE FUSERS ON WHAT THEY DO
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

Anything that can make Sarah sound like Bruce must involve Quantum tunneling….

georgie, just because your posts were deleted for insulting and attacking other members here doesn't mean you never did it or we don't remember. It's only been a day for crying out loud.

Are you trying to rewrite history?

All the best,
Nonoise

Be careful...if you tighten your fuse holder to tight, it may not work like you want it to...

Wig,

Guys,

It's no competition, QSA light blue fuse easily beats my SR orange, blue, black and my Audio Horizon fuses in clarity and all dimensions; you hear it immediately and with no burn-in.

The difference is quite startling!

It’s only a matter of time before audiophiles here learn and find out that this yellow fuse is a bargain for the sound quality it brings forth.

Wig is right on with his post.
