synergistic research orange blue fuse direction.

I trust you, if anyone can, will find a way to. : )

It’s understandable why you are reacting to ’orange’ the way you have been

It’s got nothing to do with it, but I’m sure if I had fuser voodoo skills, I could blame a Orange fuse being in the wrong way that started these insane fires, it’s about as believable as the other things they say an Orange fuses can do.

It's understandable why you are reacting to 'orange' the way you have been. Very, very sad state of affairs for the environment, nature and the extensive personal and national loss in your country. 

George, shouldn’t you be out saving Koalas

Yes and they probably have twice the brain power than what these fusers here have, and they’re stoned 24/7 on Eucalyptus leaves they eat. Hardcore they don’t roll them up. But with our fires we’ve had a few pics of toasted ones, which you Yanks poured out feelings and donations for. We give thanks to those kind Yanks.

And again starting in a couple of days more  >100 degree days in a row, with big wind, and we still have many fires burning just in NSW alone from 2 weeks ago. And also big thanks to the US fire fighters who are out here to help put these fires out

George, shouldn't you be out saving Koalas? : )

So correct me if I am wrong it is not the vertical rotation of the fuse outside the fuse receptacle and reinsertion of the fuse, but the rotation of the fuse on the horizontal plane while the fuse is in the holder. Please advise.

Thank you

Short of sticking your finger in there to see which side kills you, you will never find out which side is live, unless you are a technician with an ac voltage multimeter and have the knowledge on how to use it. And BTW!!! AC mains is non directional anyway!!!
So return them and get your $600 back, and put back the $1 worth of fuses you took out, before the return time runs out!!!.

Cheers George

Thanks to you all for your input.  The S and R on the fuse is located on one end of the fuse. So correct me if I am wrong it is not the vertical rotation of the fuse outside the fuse  receptacle and reinsertion of the fuse,  but the  rotation of the fuse on the horizontal plane while the fuse is in the holder.  Please advise.

Thank you

@guyt The easiest way is to simply test the sound quality in each direction. As others have stated, this doesn’t take long at all, the fuse doesn’t need to be fully broken in, and the preference will be clear to you.

+1 to @davidpritchard for his very helpful post, copied below:

I have tested the basic ceramic fuse that comes stock in the Pass Labs amplifiers that use a fuse. The fuse does exhibit directionally, but it is not a striking difference. The audiophile fuses I have tried have a greater change in sound depending in the direction they are installed.

The Synergistic Research Blue and Orange fuses should be installed with the "S" closest to the hot side of the fuse holder and the "R" closest to the Neutral side of the fuse holder. There are at least two ways to decide which side is the hot side. One is to buy an inexpensive circuit tester screwdriver. When touching a hot connection the screwdriver will exhibit a bright light. The less reliable method is to look at the equipment and trace the direction the current flows. This is straight forward when the fuse is located as part of the inlet for the power cord. Easy to see which side is Hot and which side is neutral. At other fuse locations current direction may not be obvious.The "S" of the Synergistic Research label should be closest to the Hot side.

Of course the other approach is to just listen to music (thirty seconds is plenty) , and keep the fuse in place where the sound is better. This can be done on first installation. You do not need to break in a fuse for 10 days and then test for optimum direction. I have done that rather tedious experiment. No need to repeat that approach.

This sort of info, is extremely dangerous to ask a gullible or non qualified technician to do, and it should be deleted, some one, one day will get hurt or worse.

I am just curious....if you buy a basic fuse direction does not matter. Why is it that the SR fuses or other high end fuses require proper directionality?

They don’t it’s BS posted up here by the fuser voodooist and shillers.

As AC mains is just that, "alternating current" that changes’s it’s direction 60 x a second, so how can a ac fuse be directional.
  
Even the snake oil fuse manufacturers won’t come on here to back some of the ridiculous claims posted that tells you something.

Just saw this from Cableco

A month after I bought three...

All fuses are directional. Final answer. And what kind of circuit are they in? On the count of three, everybody. One....two....

The difference is not subtle, not at all. In my amp, because of where it goes its impossible to tell which way current goes anyway. So 50/50, stuck it in. Right away noticed big improvement, yet it just did not sound right. Deeper, wider, more dynamic, but somehow messed up. Hard to describe. It got better but within a few minutes I knew it was wrong. Switched direction, night and day.

To think there are people unable to hear such obvious differences, well it just boggles my mind. Especially to then brag to the world: Hey world! I’m deaf! Deaf as a doorknob! And yet, there they go. We should set up a foundation, raise some money, see if we can find a cure.

Meantime listen, flip, listen. You will hear it. Assuming of course you’re not the doorknob.

SR has directions that specify the direction of current left right and the fuses are marked left right.  I find it all very confusing.  Thanks for your input.

I am sure another MAC user with SR fuses will chime in. Unfortunately, none of the fuses I know of comes with instructions. IME, one direction will sound more detailed. 

Ok thanks.   I was hoping that someone has used the fuses with Mac amps and could give instructions on orientation of the fuse in the amp respective to the markings on the fuse.  You would think that SR would give instructions that were more suited for ignorant people like myself. Thank you for your input.

@guyt,

Please excuse georgehifi post. For whatever reason, the fuse threads interferes with George’s ability to make any intelligent dialogue. Boutique fuses are poor Georgie’s kryptonite 😎

Back to your question, insert one fuse at a time. Then start listening to the music. Swap direction of the fuse and listen again, keep the direction that sounds best to your ears.

Go to the "Misc Forum" and search, you'll find all snake oil answers there.

Cheers George
