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.

tsushima1,

You assume I am trying to convince others of what I am hearing. I am sharing my experience. Others can try what I’m saying for themselves, ignore it, or ridicule it. That’s their choice, I have no control over them.

My red stones arrived Monday and I'm still experimenting with placement. They certainly have an effect on power cables but I'm not sure if I like it yet. So far sitting on power supplies seems to sound best. I'm tempted to order the blue and clear but I have a purple and yellow fuse coming so I will wait and see how things change.

I don’t mind dialoging with tsushima1, because he is able to do it in a courteous manner, without descending into mockery, personal attacks and accusations.

t_ramey,

It does seem like the red stones take at least a few days to settle in. I like what I’m hearing, but I’m trying to determine if, while certainly improving the frequencies they are targeted at, they are having any adverse effects on others? I’m thinking that, if your system is pretty neutral, or balanced, across the audible range, then all three types of stones might be the way to go. The next question is, do they play well together?

I have the reds on top of my power conditioner (CPT Equi=Core 300), figuring that way all my components will benefit, rather than just one.
