Which SR Blue or black Fuse

I'd recommend a good fashion designer to decide which color.   

I thought that’s what you are, mapman. You’re not a fashion designer? 🕺🏻

kosst, so you learn nothing ? Why are you here ? BTW, would your home made amp, as it is now, pass UL approval ? I have amplifiers in my collection I have completely bypassed the fuses and the holders ( crapola ), that SIGNIFICANTLY improved SQ in absolutely EVERY area. This tells me that fuses are crap to begin with. Once again, you cannot accept the fact that many of us hear it. Well, we do, and, that will not change. Start your own thread....pick a topic. We'll go from there. Enjoy ! MrD.

Again, admin has seen the light, on yet another thread going toxic because of fuses. And moved this thread to where it belongs.

Cheers George 

George, at least they didn't axe the thread. Enjoy ! MrD.

And yet you recommend a DAC on another thread that has as one of it's highly touted and defining features, an aftermarket fuse.

Get the Synergistic blue fuses. I have owned the black ones and bought 1 blue fuse after reading the hooplaw on the new blue fuses. Right out of the box the blue fuse bested the black fuse by a huge margin.

 Ordered blue fuses for everything. There you have it!!

kosst,
"I've had plenty of fuses blow because my amp has a massive power supply and the most basic in-rush current limiting. I've gone through about half a dozen this year."

Really can't blame you for not buying a premium fuse. I doubt they would ever break in.

You sound like a really smart guy. Question: Considering that Synergistic Research offers a 30 day, money back guarantee on their Blue fuses, wouldn't it be prudent for you to order a fuse/fuses for your amp and/or other pieces of gear to evaluate them for yourself?  There's really nothing to lose other than the shipping costs which are minimal.  I think that makes a lot more sense as opposed to becoming frustrated to the point of denigrating other members here. You may even find out, God forbid, that you are wrong.

"it sounds better to me" is a perfect example of what is empirical

Of course. As a hobbyist’s forum, users here should be comfortable reporting what they hear, and be free from demands that they provide "data," and free from insults such as that they are deluded, or engaged in a "snake oil" ruse, or other such nonsense.

This thread is: " Which SR Blue or black Fuse." It would be nice if we could keep it on-topic.

There must be an "arguing forum" somewhere on the web.  Clearly some people here derive much more enjoyment from arguing and taking shots at others than they do from music.

@sleepwalker,
What part of "direct observation" and "experience" confuses you enough to think it's not "empirical"? Go back and reread the definition.

Data is just the accumulation of those facts and observations to be used in whatever calculation or testing format you wish to continue with. That, and I don't see how hearing something can be "tangible" as that refers to something you can touch.

All the best,
Nonoise

Pass Lab amplifiers respond wonderfully to having a Synergistic Research Blue fuse installed. This has been my experience with my First Watt F-7 amp, Pass Lab INT-60 amp, and his wonderful headphone amp the HP-1.

As a bonus the fuses are easy to get to so it takes about 3 minutes to swap out a fuse. I can not think of an easier experiment to improve the sound of one's system.

@davidpritchard  You can add the Pass XP20 Preamp to that list. Blue Fuse over stock fuse.

David Pritchard is always the reasonable gentleman on these tweak threads. Thank you, David. :-)

 "I don't see anyone here trying to "sell people on fuses."

No just the same old handful shilling for the $$$$$ snake oil fuse makers. Isn't it great this crud isn't taking up valuable space now on the Amps Preamp forum, but put in it's right spot of "whatever"  

AH, yes-  Pontificating from the, 'Throne of  Inexperience'.

But ignorance is all they have, which is why they now resort to a false sense of bravado ("put in it's right spot of...") and boast as if they've accomplished something. 

It's like getting a child to eat their veggies. They refuse until they try it and then all the drama subsides. But the children have it all over these folks.

All the best,
Nonoise

Thus, my constant suggestion to the naysayers that they try the tweaks being discussed on these pages before making nonsensical comments based upon nothing but ignorance.

Coming from a "impartial poster" who’s highest percentage of post are to do with Synergistic Research products more, higher than any other product he’s posted about.
How are the SR share going Frank???

I’ve tried them and they are snake oil. 

How unlucky can one person be? Oh, well...

greg22lz....TY, I never saw that one. Enjoy ! MrD.

Ha, a glutton for punishment, I see. 

All is absolutely great, Georgie, and thanks so much for asking. I've received my massive amounts of commission checks and I just booked a round-trip flight to Tahiti. Upon return, I'll be staying for a month in my lakeside chateau just resting up from the Tahiti trip. From there, its a three-month luxury tour of Europe. I can hardly wait to see the land of my ancestors. My investment broker will be overseeing my money market account while I'm gone. Its just amazing how quickly cash builds up when you work on a 100% commission basis ... and you're really good at it. 

I post positive things about the things that are positive. SR fuses are very positive things. That's it .... Nite.,

Thanks. That was hilarious. :-)

An accurate portrayal on how we used to do it before the advent of social media.

I'm not happy about the results I reported about the Magic Fuses I tested as I know it saddens many who shelled out their tweak bucks for the things, and causes them to try harder to "believe" their fuses do things fuses don't, can't, and never will actually do...I get that...I simply say soldier on people...your gonna be OK! Now if I could just arrange that tour of the Littelfuse factory...yeah man...maybe meet Mister Littelfuse in person! I can be an "insider"...

It is important to note, that when replacing a fuse, you should not handle it with your fingers, as the skin has oils, and if these oils get on the end caps of the fuse, it can hinder the contact being made. The glass body of the fuse should have this avoided as well, as heat from the fuse will dissipate more efficiently ( this is true will all " bulbs, as a matter of fact ). This is another reason why connectors and plugs need to be cleaned now and then, from us handling them. ime…..Enjoy ! MrD.

I thought my natural body oil WAS a contact enhancer, which has kept me from showering during Contact Cleaning Week. 

So my SR Blue just arrived and I popped it into my amp's main IEC connector.  Straight out of the box it sounds a bit dark to me and the lows aren't quite as tight.  I will search the forum to see if others noticed this during the burn in period.  I know this fuse is directional so it's also possible I need to flip it around.  For the life of me I couldn't determine which way current flows through my connector (Note: I know current is supposed to flow from the S to the R printed on the fuse).  Any useful comments are welcome.

If you find the highs rolled off or recessed compared to how it used to sound, along with the lows being loose or phasey, just flip it and all should be good.

All the best,
Nonoise

You don’t have to know which way current or signal flows in the circuit since almost no aftermarket fuses are marked for directionality anyway. Thus, you should try both ways in any situation.

Flip it. One direction will clearly be superior.

Ok, I honestly can't believe what a difference flipping the fuse made.  Geez, seriously...that took me by surprise.  Thanks for the very quick and sage advice from @nonoise @geoffkait  and @david_ten .  You guys were all spot on!  The highs are back and detailed, the bass no longer loose, and the overall resolution of sound is so much more pure than using the stock fuse already.  My best descriptor would be a more realistic sound.  Grant Green's guitar sounds like it's being played out of my Mesa Boogie tube guitar amp and I could feel Ben Tucker's bass strings reverberate cleanly.  Was streaming Grant Green's "Green Street" MQA version as my reference for this fuse.  Impressed so far and appreciate your quick rescue guys.

Congrats! You just became Exhibit A.

@three_easy_payements,
Great to hear! (pun intended).

On an aside, now that you’ve heard it for yourself, and you know you’re not under the effect of a placebo, or are out of your mind delusional, or a victim of confirmation bias, or that the stars are out of alignment, do you find it odd that there are some who are so over the top furious that anyone would benefit from these fuses?

You don’t have to answer that. 😄

All the best,
Nonoise

@nonoise 

Humans have a long history of being furious about concepts, ideas, and experiences they haven't shared or can't wrap their heads around. This is nothing new.  I do believe them that either their ears, perception, or equipment (possibly collectively) can't resolve the differences a fuse can make.  I certainly went into this with high expectations and immediately felt I got ripped off as the sonics were clearly worse right out of the gate with the fuse flipped apparently the wrong way.  I clearly didn't have confirmation bias and was already preparing myself mentally for sending this thing back.

Even if I had sent the fuse back after concluding it didn't work for me or in my system I would never disparage others for perceiving a sonic improvement.  As things turned out I am one of the believers in this fuse for my equipment and as resolved through my ears (which I believe are pretty good as a lifelong amateur musician).

As for people behaving badly?...that's not a fuse issue, it's a human tragic flaw ;-)

I implore you, is it too much of leap from fuse directionality to make the proclamation that all wire is directional? Or is that premature? Talk amongst yourselves. Smoke if ya got em.

Yay ! Another believer and convert. Awesome. And, by using his ears and listening. Enjoy ! MrD.
