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.

Do you think the video I attached to his quote will pacify him?

It did answer all his statements about manufacturers engineers and actual use in production units..
the silence will be welcome to this thread, and lets talk about the topic originally started.

Like I said in capitals below, get him come on here to back the outrageous claims you fusers make about what these fuses can do and the fallacy that they are directional in the AC mains line.



To those "non technical" members that are interested, do not listen to fusers, listen to the techs of this industry that design the audio products you have.
AND YOU WON"T SEE THEM ON THREADS LIKE THIS AGREEING WITH THESE FUSERS, EVER!!!
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, bend, stretch and get crusty with electrolysis formations on their fusible wire elements before they give out, as these pics show of a fuse wire element ageing over time show. https://ibb.co/9NbTwqK
(even the $$$ boutique ones will age just as much also)

Sorry, but no, not in the least. I posted that very same video link over a year ago in another thread on fuses and he dismissed it outright without a valid reason.

He then went on about how Ted Denny should show up on A'gon and back up his claims. Well, Ted did and george ran away. Ted even went to the threads where george was posting and george just ignored him. I pointed it out to george and his explanation never made sense, and he kept knocking fuses.

Trolling fuse threads is george's hobby horse. 
You'd think Admin would do something about it. Maybe more people should complain about him.

All the best,

See what I mean? He’s just taken to copying and pasting the same thing over and over. It doesn’t take much to envision him sitting at his computer, waiting to pounce and post more annoying inanities, thinking it will wear people down and discourage them from enjoying a thread on what they know works.

He’s to the point now where he simply won’t deal with his actions of the recent past and his irrational behavior.
If you think he's unbearable here, check out his tantrums over on the Amps section dealing with Class D amps. He's insulting and abusive there as well.

All the best,
