Without an ignore button, this forum is almost.........intolerable.

Distasteful. 

I wish it would be different. I really do.
I was actually interested in this thread.


I miss the times when trolls were forest creatures that turned to stone when sunlight hit them. Folks like georgehifi are the direct result of ‘Deforestation’ 🤣


                          "THE TRUTH ABOUT $$$$ FUSES HURTS DOESN’T IT"
                            Especially to the fuse shillers boss’s 2000% profit margins.


cerberus79A few months ago I purchased a used pair of speakers from another Agon member. To my surprise all the fuses were Orange fuses. I listened to them and then to satisfy my curiosity I replaced them with ordinary buss fuses and could not hear a difference. I did this test with a bunch of friends and neither I or them could hear a difference. Im not picking a side here as I don’t give a care what people spend their money on, just relating my experience.







Hey everybody, there’s a "report this" icon that appears in the lower right of any post when you move your pointer over it. Clicking on it will send you to Admin to click on why you’re flagging the post and space to detail your thoughts.

georgie is doing his level best to annoy everyone he can. It’s like sitting in a diner and having some fool a couple of booths over yelling at you every chance he gets. Just like asking the waitress, let Admin know how annoying and disruptive georgie is being and they will do something about it. He’s had similar posts removed for the same reasons.

Stop complaining about it and let Admin know. If enough of you do alert Admin, believe me when I tell you they will remove his posts and if it georgie keeps doing it, he will get a time out.

All the best,
Nonoise
This has gone on long enough. Being a devout believer in free speech, I’ve never reported another poster to the moderators no matter how offensive the personal attacks. Georgehifi has become a true pain in the butt by hijacking every thread he enters into with his inane insults. From now on, I will report every one of his offensive, stupid threads to management until he either stops or is banned from the site. I hope others will do the same.

Frank
It is as simple as click Report this, click "Other" and type the words, "off topic". Done. Gone.  

Usually he is insulting other members, calling them "fusers" "shills" and sometimes in combination, "fuse shillers" like above. When he does this click Abusive.   

Then in comments ask why he is allowed to post when all he does is insult others for nothing more than trying to make their systems better?

I rarely post anything here. I did so this time because I had direct experience on the topic and reported it in a factual and non judgmental fashion. My reward was to be called a lier by one member and told I was in the wrong hobby by another ( I have been in this hobby for 49 years ). I am and always have been in this hobby for the enjoyment of music. I once got into a discussion with Geof Kait on the directionality of fuses and realized "why should I care or judge how others choose to enjoy this hobby ?" I think you guys have really strayed and are missing the point.
oregonpapa and millercarbon:

I agree that it's time. Like Frank, I have a natural aversion to reporting anyone who is exercising free speech. But this individual has crossed way over the line again and again. Took me all of 15 minutes to report every single post on this thread. For those of you complaining, I suggest you take the time to do the same. That is, if you are really serious about fixing the problem.
cerberus79 ...

I think I was the one who said you may be in the wrong hobby. I meant it as a joke. In retrospect, I see how it could have been taken as insulting. I apologize for that. My intent here has always been to find ways to improve my system through the experiences of others and to help others to improve their systems through my experiences as well. 

Take care ...

Frank
Keep it up, in the meantime catch this proof for your time and effort!

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.
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.
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)

BTW this is not free speech here, it is an organized scam of the highest order I have seen in audio, with profits margins that are outrageous. 1000%-3000%

There it is, can’t ask for a better test between a 10cent fuse vs a $150 fuse than that. SAVE YOUR MONEY

Kind of just says it all doesn't it?
To those non technical thinking of purchasing this fuse "snake oil" don't. Just save your $150+ and do this instead.

You/we are lucky GK has disappeared (or been banned) he was a real comic piece of work but fitted in well in these types of threads, and his website is really out there https://www.machinadynamica.com/machina5.htm best one is the pebbles.

As for your Maggies I had quite a bit to do with them owning the big Tympanies also, before going on to big ESL’s.

As you stated no difference in sound whether 10cent Bussman fuses were in or $150 SR Orange were in, to yourself or when the guys were around to do the A/B with.

cerberus79
Has the purpose of a fuse been lost ? How it is designed to work ? By design there is no directionality in a fuse. it is simply designed to open in an overcurrent situation. If it was directional in relation to the current passing through it would be a diode
Same thing I say to them, if it directional then it’s trying to be a diode, and that NOT good in either direction!


But I can tell your Maggies will sound a touch better with just a piece of copper wire soldered lightly outside of the fuse clamps and no fuses. This makes them vulnerable to an amp blowing and going dc, as you know having electronic knowledge background, but no more so than any other speaker would have no dc protection either.

You could also try one of these 5A circuit breakers if your worried about no fuse protection, on your MG 3.7i’s instead of the fuse, with a bit of luck the lug spacing could also be soldered to the outside of the 3AG fuse clamp.

I'm wondering if anyone here has tried the QSA outlets.

Wondering if anyone has any experience in this area.
I know t_ramey has a pair of red stones, has anyone else tried them? I would say that a pair of each color stone (6 total), on top of my power conditioner, has made a more dramatic improvement than putting light blue fuses in my transport, DAC and amp.

Gordon Lightfoot has never sounded better, so relaxed, real and natural!
I have a pair of clear stones taking the scenic route (thanks post office) to me this week and will get the blue or open stones next week. So that will give me the complete set, but the red stones on their own are pretty good.Would love to try one of the receptacles but it might be a while.

If you can’t hear the difference between a stock fuse and an SR Orange fuse, I’d suggest seeking out a different hobby.

Frank

If you can, I suggest you seek medical help (just giving back what’s dished out)

As I upgrade my system I’ve yet to purchase a preamp for my newly purchased SS amp and dropped a couple of light blues in a NOS Panasonic SA-HE200 reviver and was very jolted to hear a massive, scary even, upgrade of the sound quality of said receiver.

Just as everyone else said. More quiet, dynamic, larger soundstage, black background etc., and it’s only been a few evenings I’ve had the time to play my little rig!

The fuses are not even burned in yet and the difference in PRAT and is non fatiguing and draws you in to listen is only going to get better. My best least expensive upgrade ever.

I emailed Mike and told him: ’send me two black. I’m gonna take the two light blue and trade up within the 90 day grace period for a yellow’ for my new amp. He got back to me in a timely matter at that. Buy these.
Amazing, isn't it?

Something as simple as a fuse can really leave you gobsmacked to the difference in sound.
Have ordered some 1260. Think I will apply it one connection at a time starting with my yellow fuses coming.
Anyone have experience applying it to a system??
"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".

Thanks again to willgolf (and Mike) for this valuable info. In addition to the yellow for the Quicksilver preamp, I have now ordered the violet for the Rogue Atlas Magnum. Turns out the center contact for the Quicksilver is above while the center contact for the Rogue is below. Without this info, I would probably have oriented both fuses in the same direction.
 @middlemass   
If the center contact is above the left and right contacts, then the fuse should point to the right"

When you write “point to the right” what orientation?  Looking at the component from the front or rear?
 Thanks for the tip!
I'm interpreting it as looking from the rear. So, in my case, the arrow on the Quicksilver should go left to right (center contact above), while the arrow on the Rogue should go right to left (center contact below).
Any of you guys using these Fuses in a CD/SACD player?
Which level/model did you start?  Results in comparison to the competition?

Happy Listening!
I’m starting to notice an unnerving artificial recess in the midrange on closely miked instruments and voices using the new QSA Yellow fuse, compared to the SR Orange fuse. Anyone else noticing the same?

Frank
Haven't tried Yellow. Only compared Orange to QSA blue. It is not recessed, but way smoother through the midrange than Orange. Planning on getting Yellow and Violet. Tweekgeeks.com gives three months to trade up. Two months to go on that, which I plan on using to allow all the other new stuff to settle in. So we will see.
millercarbon ...

I had a friend over this morning for a listening session. We did an a/b/a/b comparison between the two fuses. There are richer midrange tones with the SR fuse compared with the Yellow fuse. I like the expanded sound stage, improved bass, and extended highs with the Yellow fuse, but it is definitely lacking in midrange tonality compared with the SR fuse. It may be a break-in issue, and I will continue working with it. I have another Yellow fuse coming at the end of the month that will go into the amp. Stay tuned. 

Frank

@oregonpapa That lush, richer midrange in the Orange fuse was the largest difference from Blue fuse for me.
oregonpapa

Thank you for the initial report. Does extended highs mean longer decay, more air,  in the upper registers?

Happy Listening!
Post removed 
Yes, I found that the midrange is a "little" laid back - my soundstage moved further back -  - and on some pieces the leading edge seems further in the soundstage - so, I suspect some tradeoff...that's why my audition took so long. Overall, I liked what the fuse did, but I don't think you are wrong on what you are hearing. On most music, I preferred what it did musically, more air space, bigger soundstage, while smoother and better dynamics. There was also a little more meat on the bones for instruments and vocals with the QSA fuse. But these could be perceived as reduction in the leading edge, perhaps? It is a system balancing act. I also got more "clarity" - 
^^^ As of last night, I'm preferring the SA Orange fuse in the line stage. I'm going to move the Yellow QSA fuse over to the phono stage where it will replace the existing SR Orange fuse. We'll see what happens there. I'll report back on the results.
