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 fuse still heats.bends and deteriorates with age. As I said to those that are interested. Just clean and tighten your fuse holder and re-new your fuse (if old) with a good quality 50cent Bussman, Littlefuse or similar, as with "many switch-on surges" they do deteriorate and get crusty as these pics show of a fuse ageing over time. https://ibb.co/9NbTwqK (even the $$$ boutique ones will age also) Cheers George |
I've never understood closed minding thinking (those that only reflect on the past - flat earthers?) - after all, exploration and discovery is what makes technology better and our lives...I have found tweaks to significantly enhance my listening pleasure...without understanding 100% why they actually work... Any speculation on what QSA is doing with their fuses? Not that it really matters - as long as they sound great...but Graphene - perhaps? I mean SR, PPT and myriads of others are using it...there is certainly something going on here - I can hear the improvement when applied properly. From a Science article...substance perhaps? One of the biggest finds is that, using Weyl fermions, the researchers will be able to create fast-moving electrons with no risk of backscattering, or loss of electrons in a collision. Backscattering makes electronics less efficient and creates heat. Weyl electrons are able to avoid collisions and eliminate backscattering. Essentially, what this means is that the Weyl fermions could provide a better flow of electricity and assist in the creation of more powerful and efficient electronics, especially in computers. It's interesting as others have found purity of copper sounds better - and they have suggested that the improved lattice structure helps with flow...and sounds better...perhaps graphene. I am auditioning some new "gear" / "Tweaks" right now. But when this trial has passed, I will move on to these fuses and outlets... |
