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.

Thanks for the reply. It looks like a yellow fuse is in my near future. I’ll start with the line stage and work up from there. All I can say is, if they can beat the SR Orange fuses, that is saying a LOT. 

Competition, allowed by the free market is a fantastic thing. Let's see who goes back to the drawing board. :-)

You just did, you called him allnoise, when you know his user name is nonoise.

I do see that the fuses show which direction they should go so that is good.
Like I said before, you can’t, the mains is AC (Alternating Current), it changes direction 60 x a second) so it’s impossible to put the fuse in the wrong way!🤦‍♂️🤦‍♂️🤦‍♂️

Keep writing on the subject of aftermarket Fuse(s). I am enjoying reading your thread. Does QSA cite the life-span of their products?

Happy Listening!

Absolutely!
A win/win every time.
