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.

Wisper,

yellow fuse took the  X2 20% better, like on steroids.

Red black you don’t want to know. Don’t demo it. It’s a very strong drug like experience. Mike @TG is a pusher of this drug like item.” Here, demo this”, now I am ruined. Doesn’t matter what the little Eeyore’s write or think. Let them dial up for internet connection, watch a 12” B&W TV and have a rotary telephone with a wire.  🙈🙉🙊

Ok, will give it a go with a demo and let the ears decide. Thanks for everyone's input! This is what I like about these forums. Also, thanks to those that respond to private messages about this hobby - it has enhanced my listening pleasure and also my enjoyment of this hobby. 

I wish the moderators would put a stop to Georgie, it just distracts from threads. Maybe the moderators think it gets more eyeballs? Anyway, those that feel the need to be right all the time have fragile ego's - many are obsessed with trying to be right and winning every argument, in the end, they’re going to be viewed as less credible and not worthy of following. No one knows 100% of everything. Humility is a key leadership trait. Set aside the ego, embrace vulnerability and the fact that you can be wrong and don't have to be right all the time. If you are not prepared to be wrong, you will never come up with anything original. Ask Edison.

oregonpapa-
As an "old dog" myself, who has learned a ton of "new tricks" over the past few years, it would be a pleasure for any of the naysayers to hear my system, and then with a straight face tell me that these so-called "snake oil" items don't work.

Indeed. I have a feeling the reaction upon hearing either of our systems would be https://youtu.be/JM9HmdnbqwE?t=47 followed immediately by
