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.

The yellow I ordered for my Audio Note el84 amp came when the light blue did. I didn’t install it initially so I could get a handle on the light blue and what it was doing with my dac. I have a AM beeswax premium fuse in the el84 amp and the yellow didn’t have as big of a jump as the light blue did on the SR Orange but still thought it was a nice improvement. Both the SR Orange and AM beeswax had Total Contact enhancer on them and after applying it to both the light blue and yellow they’re definitely an upgrade over the previous fuses. I have another yellow coming for a class d amp so the tube amp can rest during this heat wave in the southwest, or as we call it in AZ....summer.
Hey folks, it's only a $71 dollar item. Where did all the nannies come from? Instead of lining up like good little trolls, all you have to do is peruse the forums. It's all there, including all the lame comments.

You're contributing nothing new and skipping the first thing about science: direct observation. If you have any doubts, it means you have to see/hear for yourself. Stop being intellectually lazy and relying on all the heavy lifting being done by someone else, so you can point to some generic manual like it's the bible. It makes you look silly.

All the best,
