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.

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.
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 just as fast also)

And you were showing such promise.....

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?

No quite the opposite, it gives the non technical the technical views from the non voodoo side of the fence also, so they can make an informed choice.

Cheers George
