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.

there are some reliable, known members here that seem think fancy fuses make a difference sonically - but many more that don’t

in all my years pursuing high end audio, i personally have never paid attention, nor tried...

that said, i do notice, and am very much on guard (coming from a business background) about potential guerrilla marketing tactics being employed when the product itself has gross margins to the order of several hundreds of percentage points -- same for megabuck audio cables, magic damping dots... and so on...
Regarding the profit margins on these fuses, we can speculate all day long, but we really don’t know.


we don’t know exactly, but we know - we know the profit margin is exorbitantly high... much more so (as in several mutiples, at least), than that makers of active components, loudspeakers, in this industry...

not taking anyone’s side in this -- just using common sense, and some basic business acumen

no it was luke skywalker’s great great great grandma - amelia earhardt!!!

side note -- one thing that i learned in this thread, is if you have to... like you HAVE TO... JUST HAVE TO have the last word... each time, every time, all the time

that is how you get to 10,000 posts in a hurry on this goofy forum
Here is what I posted on the other thread.

So I received my first yellow fuse for my Dac.
First minutes of listening, its just ok. Actually, I don’t think it is any better than my SR orange. But that fuse was treated with the High Fidelity 1260 contact enhancer. And perhaps I was expecting more based on all the chatter.
I have 2 more yellows to receive for my amps, so we shall see.

UPDATE: Now, a day later still no great revelation in sound quality.

dammit man, you need to get with the program ozzy

what you are saying is NOT OK... how recently have you gotten your hearing checked? or maybe you are just NOT trying hard enough to hear the difference these AWESOME fuses make...

did you compare to a home depot bussman fuse?????

🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
