Has anyone experienced a little harshness in the highs? I just put 2 blue QSA fuses in both my Innuos Zenith server/streamer and PrimaLuna EVO 400 integrated. I did notice more openness and greater separation and some dynamics. I listen to a lot of female vocals like Sarah Jarosz and Norah Jones and seem to get a little bit of shrill on the upper most notes. I have had them in about a week so they have maybe 15 hours on them.
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 still in the auditioning phase. But, I am experiencing break in for sure and for me at least a rather lengthy one. What I don't know is whether the various color fuses all break in the same way? i.e. longer time frame, shorter time frame, different type of break in etc. Also, different equipment may respond differently...I am auditioning a RED fuse, so cannot comment on the blue fuse. But I think it may be a bit early in the break in phase. |
So I just pulled the trigger on a used SR Orange Duplex (220$) and a used SR Orange Fuse (100$). I have another orange fuse already installed in my converter and I loved what it did. They're about to be delivered today and I was all excited... until I came across this post. Seems like a whole lot of y'all are in agreeance that these QSA fuses are better. Does the SR Orange beat it in any aspect? ( detail , bass, soundstage ) Also has anyone tried their duplexes? |
It’s possible the higher up you go the longer the break in. Mike at Tweek Geek said his Red receptacle took quite a while to get to where it finally settled so maybe the idea is that the higher up colors have more of the "treatment" and need more time. Just speculating. Anybody order the new magic stones? I’m going to try the red, figured what the hell it should be fun. https://www.tweekgeek.com/qsa-stones-set-of-two/ |
