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.

Isn't it interesting that you started a new thread about your experiences with a new tweak, hoping to turn others on to what you've discovered, only to have the Negative Nellies, and Debbie Downers come out of the woodwork to mount their ignorant attacks?

My take is ... they have no idea what you have done to your system to gain the resolution you, and others have achieved. Those of us who have gained that level of resolution fully understand.

It is their loss, not ours.

Thanks for trying the new fuse and for bringing the information to the rest of us. 

Take care ...

From Tweek Geek's site regarding the fuses:

  • "We want you to try these fuses, and keep trying them. We are convinced that you will hear the value that these devices offer. So it is with this in mind that we are offering our 90-Day Trade-Up Program: If you try a QSA fuse, and within 90-days wish to upgrade, we will give you full credit for the fuse you purchased towards the fuse upgrade as long as you have the original fuses' box, and the fuse itself is in excellent condition."


  • "Accidents: If you cause the fuse to accidentally blow during the warranty period, we will replace it one time."

  • "If you try one of these fuses and don't think it is worth the investment, simply return it in its original packaging and condition, and we will refund you the purchase price. You have our word."

Not too shabby, eh?

I wonder how many folks who post here on A'gon also post negative reviews on restaurants they have never eaten at?

1. Isn’t using the term "shill" to describe a fellow member akin to a personal attack?

2. Every manufacturer in the hobby marks up their products. Most manufacturers of electronics mark up their products 100% to the dealers, and the dealers mark them up another 100%. In other words, a product that costs $2500 to produce, is sold to the dealer at the wholesale price of $5000. The dealer then marks it up again to the retail price of $10,000.

Why no complaints about that Georgie?

How about cartridges, Georgie? To date, I haven’t seen you complain about Koetsu Coralstone cartridges or other cartridge makers like Lyra, etc. How much more could it cost to produce a $10,000 - $15,000 cartridge than a $1500 cartridge ...  or a $200. cartridge? 

What gives, Georgie??

Thanks for the reply. It looks like a yellow fuse is in my near future. I’ll start with the line stage and work up from there. All I can say is, if they can beat the SR Orange fuses, that is saying a LOT. 

Competition, allowed by the free market is a fantastic thing. Let's see who goes back to the drawing board. :-)

I just ordered a yellow fuse. It will take a while to get here as Tweak Geek is out of inventory at the moment, so they are accumulating orders and will send them off to the mfg on the 15th.

Frank.

PS: Nonoise ... Please count me in on one that is not interested in what Georgie-pie has to say.
Come on guys, let's give Georgie a break. Everyone knows that measurements will tell you exactly what you are hearing and that you cannot solely rely on your lyin' ears.

I went to a family picnic today. There was a relative there who knows everything about everything (you know the type, I'm sure). He argued up one side and down the other that Tesla was promoting DC power and Edison was promoting AC power. He was very adamant about his position and wouldn't move off of the subject. I told him to take the DC batteries out of his flashlight and plug it into the wall. You remind me of that guy, Georgie. These aftermarket fuses improve SQ as claimed. Seriously, you should try one. Your position is as ludicrous as that guy at the picnic.

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.

Frank
Georgie ...

I took your advice and changed out all of my SR Orange fuses for fifty-cent Bussman fuses. The clarity went away. The three-dimensional sound stage flattened. The natural tonal quality of all instruments became plastic. And to top it all off, The Bussman fuses made Sarah Vaughn sound like Bruce Springstein.

Question: Am I experiencing a break-in problem with these Bussman fuses, or do I just not have them inserted in the proper direction?

Frank
I believe Tweek Geek is accumulating orders and then sending them to the supplier all at the same time. They said that an order was sent out on the 15th ... two days ago,

Tommylion ...

Where did you place the stones? Do you have any of the other stones offered by Tweek Geek? If so, did you hear the differences between the stones? Thanks ...

Frank
The Yellow fuse arrived today and I placed it into the ARC REF-3 line stage. In my opinion, it is one of the best tweaks on the market and well worth the money by far. Everything improved over a three-hour listening session from top to bottom. The three-dimensional presentation placing the performers on the stage is really quite remarkable. The human voice is much improved. Mel Torme’ was in the room. I don’t know how much more noise is left to be removed from the system, but evidently, there’s plenty more.

I went straight from the SR Orange to the Yellow. The system was already at such a high-resolution level that I thought there wasn’t much more noise left to be removed. I couldn't have been more wrong.

Let’s hear it for the free market. Competition helps to drive it. With the improvements afforded by the Yellow fuse, I can’t imagine anyone beating it anytime soon. But, there are those in the business who won’t be sitting still. We shall l see.

My God ... what does the top of the line sound like?

Just as an experiment >>>

The Orange fuse that I just took out was treated with Total Contact. I put the new Yellow fuse in without any contact enhancer just to see what it sounded like untreated. I'll get it completely broken in, then apply TC to it.

I had a dream last night that all of the A'gon naysayers came over for a listening session. It was quite a crowd. Instead of listening to music, they all sat around discussing equations and slew rates. I  had to leave the room for a moment and when I came back they were all gone ... and they stole all of my records. My very first thought was ... what in the hell are they going to do with the records??

Further evaluations on the Yellow Fuse vs the SR Orange fuse:

A friend, a very experienced listener, record collector, and audiophile came over this morning. We spent the time doing A/B comparisons. It is very easy and quick to do on the ARC REF-3 line stage. Here’s what we came up with:

New Yellow Fuse: Much deeper and more articulate bass. Purer highs, more overall clarity, and faster. There is a more well-defined front-to-back and side-to-side soundstage. Quite remarkable, indeed.

The SR Orange fuse: So far it loses out on all of the above areas, BUT .. it has a more liquid midrange. It is more tube-like in a very good way. From a musically involving standpoint, the SR Orange fuse still wins the day.

At this point, both fuses have their strengths. Ultimately, I’m hoping that things will improve with the Yellow fuse’s midrange as it breaks in more, as I’m only about ten hours in on it. If it can eventually match the beautiful midrange of the SR Orange fuses, then indeed, we have a true Allstar.

I recall, the SR Orange fuses needed about 50 hours of break-in to sound their best.

All of this is system-dependent of course. In the meantime, I’ll be holding off on my second Yellow fuse purchase until the current one is fully broken in.

Stay tuned ...

Frank

PS: The Orange fuse has been treated with PPT Total Contact, and the Yellow fuse has not.
