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 am also happy to have an alternative to SR. The fact that it is quite a bit less expensive is a bonus. I would love to hear what the upper end QSA fuses can do in my system, but it’s not very likely, any time soon…unless some generous benefactor lets me borrow one😉

Meanwhile, I am loving what the the last light blue in my amp brings. The increase in realism on vocals is especially noticeable.
Ordered a yellow for my EAR 868 preamp. 
My first "designer" fuse.
I've used other tweaks discussed here with great success. 
Will report back with results

"It is all the same story, just nobody wants to believe it. Study all my posts, figure it out. Bonus, if you do study them all you will instantly become the second most well-informed person here. Even so, I cannot guarantee you will be able to figure it out. But take my word for it, the info is all there."



Word.
From Tweek Geek's site regarding the fuses:

  • "We want you to try these fuses, and keep trying them. We are convinced that you will hear the value that these devices offer. So it is with this in mind that we are offering our 90-Day Trade-Up Program: If you try a QSA fuse, and within 90-days wish to upgrade, we will give you full credit for the fuse you purchased towards the fuse upgrade as long as you have the original fuses' box, and the fuse itself is in excellent condition."


  • "Accidents: If you cause the fuse to accidentally blow during the warranty period, we will replace it one time."

  • "If you try one of these fuses and don't think it is worth the investment, simply return it in its original packaging and condition, and we will refund you the purchase price. You have our word."

Not too shabby, eh?

Imagination is a wonderful thing!

So will "electronic knowledge" gullibility and stupidity, make them susceptible to this AC fuse snake oil **** ****
