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.

Sorry, I attack the BS being preached about these $$$$ fuses. Not personally the ones saying it, BIG DIFFERENCE.
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,

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.
I am using SR oranges in my MSB V DAC and transport at the moment. What a tremendous upgrade in sound quality from the standard fuses I am trying to get some QSAs but not so easy in Europe... Really looking forward for them. Want to start with the yellows
I love it when competition drives innovation and we all benefit. Seems SR has some work to do to regain their top quality position in the growing high end fuse category.

I suspect the fuse category will continue to see innovation and that is exciting!
