Let us know how the QSA fuses sound. That's a LOT of money for a fuse. A couple of hundred bucks I can rationalize. I don't think I have the equipment to support a thousand dollar fuse upgrade..... Synergistic Research puts out some good stuff. About the limit of my wallet, too.....but if you have the money, by all means report back with your experiences on the QSA stuff. |
"voltage conditioning process" ??????Really! fuse can do this🤦♂️ I'm a little late to this party, but I can attest that adding 2 SR Orange fusesReally! a fuse will do this🤦♂️ Wouldn't surprise me if Synergistic Research and Quantum Science Audio, are one in the same, now that SR has fallen from favor and Quantum is the new cheaper snake oil fuser on the block. All that the members need to know that are thinking of buying into this fuse snake oil is A fuse: 1: two end caps 2: short piece of fuse wire connecting the two end caps through a glass tube (that’s all she wrote). I ask what can be done to that 10mm of fuse wire, by these companies that have no technical credibility at all 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 FUSERS ABOUT THE SOUND IMPROVMENT DETAILS AND AC FUSE PLACEMENT DIRECTION, EVER!!! Just clean and tighten your fuse holder and re-new your fuse (if old) with a good quality 50cent Bussman, Littlefuse or similar.Cheers to those "non fusers" George |
I discussed the fuse issue with a friend who is a manufacturer and audiophile and super knowledgeable. He simply says that you hear a difference with the QSA fuses because they increase the voltage flow. Seems logical that a stock fuse creates a kind of bottleneck. The colored fuses open it up. However, he also says to run away fast if someone tries to sell you a $2400 fuse. |
I had to go up from 4 to 6 with SR blues Slow Blows on the AC side. The other side of the power supply, I kept the same values in SR Orange At about 25-30 hours I was playing CDs over and over and over.. That just doesn't happen.. I was leaving that tube amp on 20-30 hours at a time.. I would bypass every fuse in that V12r IF I didn't love the thing.. I'd hate to hurt that amp.. Great amp... A lot of expensive transformers in that puppy.. I think the reason why it sounds better. There is ZERO Nano arcing after it settles. There is a reason WHY they work.. And why they sound different one way than the other. The draw of the filament through the dyes, the taper and number of progressive wraps on a SB fuse.. It makes sense to me. You measure the resistance in the fuse one direction and it is less in the other direction. Same with cable. I have 2 71.00 usd models on the way.. I need a geiger counter, just to make sure there is no funny business. Could be a plot to sterilize my rabbit.. :-) Regards |
thecarpathian <<< I used the manufacturer's suggested value ratings on both the SR Orange and the QSA fuse. Frank |

Frank, My system was sounding pretty glorious, too. The SR Orange fuses really, really make a difference. Not cheap, but in my system very, very worth it. Everything makes a difference. Power cables, interconnects, fuses, room tweaks, all of it. Add up all the little things, and you get a BIG difference! I've not tried all brands, but I will say this......I used to choose not to believe in this kind of stuff, it didn't make sense. Then I tried a few......and while it still doesn't make sense to the logical side of my brain, the other side of my brain (the one that listens to the music) simply can't be ignored. I have no idea how or why some of this stuff works. But it most certainly DOES work! |
Just the same responses from the same gang of shillers for fuses that have 1000% profit margin, no overheads no technical degrees, just click and collect the cash. No wonder they are hard at it, no legit business model makes that kind of profit margin legally. It's a scam of the highest order in audio. Audiogon needs to look closely at this like over at diyaudio, and purge it from these pages. All potential purchasers need to do is read and do this: A fuse: 1: two end caps 2: short piece of fuse wire connecting the two end caps through a glass tube (that’s all it is). Ask what can be done to that 10mm piece of fuse wire, by these companies that have no technical credibility at all, and can't give any. 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.

Guess your ears can’t hear what mine do.5 post and with attitude?? Ya gotta earn that privilege here sunshine I'm a little late to this party, but I can attest that adding 2 SR Orange fusesReally "jaw hanging open", you must be the latest fueser shill recruit |
Please don’t argue with, or try to convince, George on this thread. I always thought SR and new guys like this Quantum were using some kind of voltage conditioning process on the fuses, and the fuse price/level was just the amount of time that fuse spent on the conditioning device.

Tim Mrock was ahead of his time. His stuff was and is awesome. But nobody keeps great stuff like that secret for long. Lots of people are on to it now. NPS1260, what do you think that is? SR fuses and outlets, the glob of gray goop they tell you not to remove, what do you think that is? I'll give you a hint, the top end QSA Red and Black fuse uses so much they had to stick a piece on the side. Millercarbon are you saying the key to these fuses is amount of 'special secret sauce' contact enhancer applied? I always thought SR and new guys like this Quantum were using some kind of voltage conditioning process on the fuses, and the fuse price/level was just the amount of time that fuse spent on the conditioning device. But if the key is contact enhancer, then it becomes easier for DIY to replicate. |

Let me get this straight. I specifically give you 1 video of Paul McGowan
videos about fuses, coming directly from his mouth. Paul McGowan the chief electrical engineer and CEO of PS Audio completely revamps his fabrication process to make his ENTIRE line fuse friendly and you still don't believe? Ok, no problem. So why do you even take time out of your life to even post here? Is it that your only interest is to get 10,0000 posts? Just saying. |
You guys can’t leave it alone, still trying to jag a bites?? Keep it up, in the meantime catch this for your time and effort! Ask Paul McGowan to come on here to back what you lot say about the sound quality improvements and especially the ac fuse directionality you fuser claim, then there will be some substance in what you lot say, if he does I’ll be the 1st to give it away. He also backed MQA at first and bought into it!!!!, and now put’s **** on it because he looked silly for backing it at first, now that the odds are against MQA for being what they say it can do. Same will happen with the fuses, he’s goes where the $$$$$ are, and you can take that to the bank.. A fuse: 1: two end caps 2: short piece of fuse wire connecting the two end caps through a glass tube (that’s all she wrote). 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.

@middlemass, Great info. I've ordered the yellow for my preamp. This will be my first ever fuse upgrade and the directional rules had me a little confused. Sometimes it takes a little courage asking the questions you want cause no one wants to look 'stupid' to others. And asking that question, couldn't be more farther from the truth. So if you don't ask...You won't know. @georgehifi, doing research on fuses about 3 years ago I stumbled upon this 2017 you tube video by Paul McGowan the chief electrical engineer of PS Audio about 'Audiophile fuses'. He didn't believe that something as small as a fuse could effect sound quality either. https://www.youtube.com/watch?v=kFlnQ1chBno Well, he does now, in fact he has completely changed the design of his products to make them more fuse swapping friendly. Don't believe me, go to his PS Audio blog and you will see years of PS Audio customers sharing their stories on fuse swapping. I got 2 light blue on the way and within ninety days - a hell of a long grace period, I'll probably get a yellow, and then... |
I have questioned which way to point the fuse. I have 4 yellows in my system. I questioned Mike from TG's and this is his response... "It depends on the orientation of the iec input on the back of the component. if the iec input is oriented so that the center contact is below the contacts on the left and right, then the hot is on the right side, and the arrow should point to the left. If the center contact is above the left and right contacts, then the fuse should point to the right". I hope this helps others as it provided clarity to me and now I don't need to mess around. In conjunction with the Townshend Podiums and the yellow fuses the music is sounding pretty damn good. Next for me is I just ordered 16 Western Electric 300B tubes for my amps. Hope all have a good weekend. Blind Will |

oregonpapa-
I'm having a hard time wrapping my head around just how good this fuse is. As it has continued breaking in, the midrange is coming into its own very nicely. There is a concrete realism that was not there before. The human voice is amazing.That is quite the statement, knowing as I do your standard for "good". But even knowing that as I do, I would have to agree. And I haven't even heard Yellow yet, but only the light blue one. Just spectacular, head-shaking good stuff. I'm even thinking of trading my blue in towards a yellow, and also maybe a violet. You only live once, right? (That we remember, anyway.) |
The only place a fuse has an audible effect is if it is placed in series on one of the + or - conductors of speaker wire. It will increase resistance and decrease damping factor. A bad way to protect a speaker from excessive voltage!
<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>> jasonbourne52, This is exactly where I found out about fuses and their effect on speaker SQ. I am still a BIG fan of the old Infinity RS and IRS series speaker.. I'm going to add dampening through a passive XO is NO dampening AT ALL. ADD a fuse or four (4) and they takes the brunt of that type of fuse arrangement. None the less if you don't bypass the fuses circuit or keep it in VERY good condition along with all the LPads.. SQ is the first to suffer. The first time was QLS1s the second was RSIIbs in the 80s. NOW add a 1 ohm load in the mix like the Kappa 9.0 or 8.0 series and you have a disaster because of a FUSE and ZERO dampening to boot because the drivers are NOT direct coupled to the bass amp. George understands how an amp works VERY well and so do you, it seems. My question is why not try a fuse in the sound path and see if it makes a difference. IF you read some of the CRAP I post, you'll see I had much better luck using "The Fuse" in the path and less of an effect in the PS AC path especially with amps LIKE, First Watt, Pass, Mcintosh, etc. BUT in a NP design with fuses on the other side of the AC PS, fancy fuses not only made a difference, in some cases it lead me to BYPASS the fuse circuit all together.. Carys V12R is an exception to the rule. I use a great AC power cable and a blue SR fuse (from an ACME gold) with great success. BUT I really didn't notice the BIG change until I change the fuses on the other side of the power supply. The V12 has THREE. The same way with the NP design had 2-4 depends on the design.. I'm not saying spend the big money, I'm saying that in quit a few situations IF the fuse is put in the path between good parts (Power supply to amp rail), WHY would you want to feed the amp module with the cheapest piece of lead/tin/aluminum/whatever you could find. Much like a standard Busman fuse. On either side of that fuse holder is GREAT copper, silver or silver clad wire. It's not a bottleneck at all, it's straight up a fuse with TONE control.. :-) Mechanically I can explain my position, technically, I may lack the understanding of WHY, but I do know where to look for the greatest improvement in spite of the COST of a product.. Regards |
Pleased the QSA thread is open up again. Sure wish people with experience with the fuses and stones would contribute more. Being so incredibly impressed with the light blue fuses, I ordered yellow fuses and red stones. Curious about the stones? Going to try placing them on the power supply of my preamp. Curious about Total Contact or 1260 Enhancer? Curious about the Bybee V2? |
docknow >>> I'm having a hard time wrapping my head around just how good this fuse is. As it has continued breaking in, the midrange is coming into its own very nicely. There is a concrete realism that was not there before. The human voice is amazing. While the SR Orange fuse was the benchmark in all of the fuses I've tried over the years, the QSA Yellow fuse has it beat hands down. No contest. How one little fuse can make such a significant improvement is way beyond me. When paying $213 for a fuse, which to most, seems like a ridiculous sum, one has to measure the cost by the results. I've used ICs and PCs costing ten times as much that haven't given the results this little yellow bugger is giving. At this point, I'm thinking that other fuse manufacturers will have to go back to the drawing board in order to stay competitive. That's honest to God's truth. In fact, I'm ordering another one that will go into the ARC-REF 75se. Frank |
Guys, after extensive break-in...and yes, it was really "wonky" along the way and it took way longer than I thought it would for a "simple" fuse...but I have gone ahead and kept the "red" fuse for my Sorcer x4. I would say the break in was ~30 days? Not exact on this one, sorry. I did hold off on my assessment because the break in was again, wonky - bright, dark, etc...and kind of fluctuated...took a while to really settle in. Basically, I hear more air, bigger soundstage, more depth for sure, more detail, but also more relaxed at the same time - more musical. Interestingly, some of my recordings are "more" listenable, more musical. They were good before, but now are more enjoyable. I did not use any paste as I wanted to "hear" the fuse and the fuse alone...I may experiment with paste later on, but I like what I am hearing now. Based on this I would recommend a demo and let your ears and wallet decide. |
"The theory, wraps all these errors and fallacies and clothes them in
magnificent mathematical garb which fascinates, dazzles and makes
people blind to the underlying errors. The theory is like a beggar
clothed in purple whom ignorant people take for a king. Its exponents
are very brilliant men, but they are metaphysicists rather than
scientists. Not a single one of the relativity propositions has been
proved. " "I hold that space cannot be curved, for the simple reason that it can have no properties. It might as well be said that God has properties. He has not, but only attributes and these are of our own making. Of properties we can only speak when dealing with matter filling the space. To say that in the presence of large bodies space becomes curved is equivalent to stating that something can act upon nothing. I, for one, refuse to subscribe to such a view." This is, of course, Tesla refuting Einstein's theories. He couldn't "get his head around" Einstein's work and made a number of strong statements regarding it. Possible to be very intelligent and very wrong sometimes! |
Are audio fuses directional? A: Yes, fuses are directional. Electricity should flow from the left to the right when you view the fuse. If you do not know the direction of flow you should listen to the fuse inserted in both directions. One direction will sound more detailed. Does fuse affect sound quality? What I mean is lower energy signals will be impeded more by this higher impedance state of the fuse on those bass notes that "pulsate" the fuse. So, yes, anything in line with the signal can affect the signal or sound. This pulsation is also not linear, so that also can affect the sound. I repeat Fuses do make a difference and "are directional" If you have not listened to fuses you do NOT have an opinion.. Be nice and go away! Bye Bye ;-) |
Please do not make this thread about George. He clearly has a personal vendetta against products and posters he disagrees with. His purpose in posting is to stir up controversy, draw people into fights and get threads shut down. His clear mission is to suppress open discussion of topics that offend him. I do not understand why he is allowed to continue with this kind of behavior, but it is what it is. Engaging with him, however outrageous, provocative and hate-filled his posts are, Will only help him in his twisted crusade. |
