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.

Looks as if there will be numerous used SR fuses for sale in the near future.
Question:
If I am not mistaken, SR suggests buying their fuses with a slightly higher rating than the stock replacement. Does this also apply to the qsa fuse?
Competition, allowed by the free market is a fantastic thing. Let's see who goes back to the drawing board. :-)
Absolutely!
A win/win every time.

I'm sorry jjss49, but that is historically inaccurate. Although commonly attributed to Luke Skywalker, in-depth archival research at Washington's Air & Space Museum shows that it was in fact first uttered by Orville Wright, the night before he forever changed history by inventing his brother Wilbur.
Then how does the guy at tweekgeeks know which one you need, and how do you know your SR orange fuse is compatible?
