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.

My Blue is delivered. I will try tonight. Compare with Synergistic Orange in there now. 
One of the three will be incoming AC for the whole amp. Try that one first. 
When you little scamps get together you're worse than a sewing circle. 
Props to whoever can find the clip.

Chuck please do tell where the fuse installs on the Blackhawk. 
? Coulda sworn you had one?!
May have jumped the gun but it sure looks to me like it is one of those where the fuse is incorporated into and directly below the IEC connector. There is no mention of a fuse at all in the Owner's Manual (pdf on-line) but the pictures look so exactly like that I didn't even bother to call and ask.
My Raven Blackhawk just shipped. New amp calls for a new fuse, right? Michael at Tweekgeeks.com said they have the one I need, so a small Blue will go out tomorrow. This will give me the chance to directly compare with the Synergistic Orange. May the best fuse win! lol!

As an "old dog" myself, who has learned a ton of "new tricks" over the past few years, it would be a pleasure for any of the naysayers to hear my system, and then with a straight face tell me that these so-called "snake oil" items don't work.

Indeed. I have a feeling the reaction upon hearing either of our systems would be https://youtu.be/JM9HmdnbqwE?t=47 followed immediately by

Okay. Goofy reasoning but okay. But you did not say vitriolum, you said vitriol, the plain meaning of which is cruel and bitter criticism. Alternate meaning, acid.  

As painful as it is the truth is so powerful that to try and stand against it, as you so often do, winds up destroying your credibility. Done too often you risk being seen as a crank at best or worse, a stubborn fool.  

We wouldn't want that now would we?
Vitriol is cruel and bitter criticism. Why would anyone who favors fuses have vitriol for it?
The Blue in my Blackhawk is awesome. The very best components improve detail and dynamics while also somehow managing to be more liquid smooth. The Blue does this better than any component or tweak I have ever heard. It was good right out of the box, and now is so good it is like its not even there. By which I mean zero artifacts or evidence it is doing anything. Everything just sounds so much more real and "there". Thinking of using their 90 day option to upgrade to Violet, and maybe Yellow in the Herron. 
Immediate impression, at least as good as Orange. Slightly smoother, more liquid, yet also more dynamic and lots of subtle details coming through with a more natural sense of ease. Part of this undoubtedly is the Raven getting more hours. Whatever, and however you want to parse it out, there is just no doubt this is a damn good fuse and a bargain for under $80 with shipping. I will probably be getting at least one more, and maybe even try the next one up the line for the Herron.
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.
