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.

Instead of being yet just another fuser that can only personally attack, attack this instead with some technical opposition instead

. 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 THESE FUSERS
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

I just heeded Eeyore’s 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.

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.
What's with all the projection, georgie? You've had posts removed for your personal attacks, trying to be clever. It's all you seem to be good for, aside from posting the same irrelevant rants.

All the best,
Nonoise

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"
