Great! Thank you for the golf fuse pic! It seems you’ll be curious to add another SR-M to the MK II soon…

The Master fuse, by tomorrow, I expect to sound even better. SQ defination is tighten up. But, it has not reached the smoothness yet, I enjoy it but can not listen to it for too long.
It is like a young wine that tasts a bit spicy, it needs more time to develope.

As I understand things, Current flows from the internal holder to the “cap.”
It was designed this way, you can never have current on the fuse hanging out of its holder, if that makes sense.
Thus, if you want current to flow from S to R, you want the R end pointed into the removeable cap…

In the early stage of trying out, I will switch the fuse direction again later. If I hear better SQ that will be great since my wife still likes the sound with the stock fuse so far. 
Oh dear, all this confusion over the correct orientation of the Master fuse.
Waymanchan and others seem to prefer the R closest to the cap and he and Andynotadam seem to confirm current flows from the P20 to the cap.
I’m actually waiting on the postman delivering my two Master fuses, one for my UK mains plug and the other the internal fuse for my P20. (Changing from a AM-M1).
I’m going to start of dchang05 way with the S towards the cap but I expect to settle on the majority of owners with the R towards the cap.
If the consensus is that the current in the fuse flows in the direction of the S → R and current flows from the P20 to the cap then the S on the fuse should be farthest from the cap, so holding the cap holder you would read SR left to right.
Once I’ve decided on my preferred orientation I’ll change out the UK mains plug from the Purple to the Master.
Here is my new strategy. Based on SR past experinece, both of Orange and Purple need 200+ plus hours of break in. I believe the Master will need similar time in my system.
I will listen to the current setup (s inside holder), then switch the direction. I will let it stay there for one more week. By then the fuse should be close to finishing break-in. Then I will switch direction again for a few days.
Hopefully by then I can judge which setup I like better without worrying about the break-in effect.
Or, Al could be rigth that fuses do not really make much differece, let alone fuse direction.

Can’t remember where I read it but the poster thought that doing burn in one one direction and then reversing the direction might not get the best out of the fuse as it’s got ‘set in it’s ways’.
Much better to determine which direction sounds best before you burn the fuse in.
I’m still waiting on mine arriving and it’s starting to not look good for delivery today.

Maybe it matters less then. Both of my Purples in other gear are with S inside the holder. I love the sound. Maybe that’s why I like the same direction of Master too.

Hey sheridd2
Long time “fuser” user “hear”…go back to the start of the thread and spend some time
reading through…will be very helpful.
So because I had forgotten which way sounds best I shut down everything flipped the power switch to off
on my P15 removed the fuse…in my case the S of S/R goes into the fuse cap…is what I have found.
In my case the with the fuse oriented this way the air, the presence, quickness soundstaging
in all three axis…as someone here stated: “Like technicolor” to which I added include with that
cinemascope, cinerama as well as imax …in other words music comes to life far more than
any fuse I have ever used: HiFi Tuning Supreme3, SR Blue, Orange, Purple, AM M1 in the
P15 position…
With the M1 in my Parasound JC5 the life of the music’s body, the swell of the music increases
as well as bloom over the Purple while maintaining all that the SR Master has brought to the table.
SR Master has permanent home in my P15!!
Yes the SR Master has more body than the Purple while doing everything else I have described
without any of thr Purple’s tendencies for thinness or harshness experienced during the Purple’s
burn in time.
In essence then my .0002 is that 1st fuse goes to your P20 by hearing and listening find
the best dynamic orientation…
Then and only then add the 2nd fuse to the UK mains plug…if you don’t follow this order
you will incur a much harder time figuring out what is going on…with a lot of frustration to
boot.
My hope is that this will be of good help for you and others that may read this thread…
Again read the whole thread as I have given a pretty good run down on what the new SR
Master fuse has done for my system
Best wishes in your journey

Hey Donald hope your new SR Master is “cooking in” well…
Like you as well, regardless of what Audio Magic says about the non directionality
of the M1 fuse…I find it to be directional as well…orientation makes a huge difference
for me…
What I find odd though is that your SR Master fuse wasn’t “dynamic open quick” as it was
for waymanchen and myself…
Should your new SR Master not come about and perform get back intouch with John
at the Cable Company ask for an exchange or refund while you are in the 30 day return
window.
Somehow I don’t think your new SR Master would make a decent Tee…for golf 
Wishing you the best

Haha, last night was the first time I felt the tee Master’s power. I finally could feel what you felt. I think I got a slower one here but it should be fine from now on.
I am going to switch fuse direction a couple times today. The goal is to totally confuse me, or to find they matter or don’t!

You must have a lot of time on your hands 
Have fun choose the most well known disk select a track with strings, piano
horns…and use the same section…the correct position will be obvious very
swiftly…

Okay, received my Master fuses today after all and I’ve already formed an impression.
First on orientation.
I’ve used Paul Simon, the Ultimate Collection CD as it’s very well recorded.
I played the first six tracks with the fuse in each direction.
I tried with the S in the fuse cap holder first, findings as follows :0
- very polite and clean.
- very tuneful, inflection in the vocals drew in me as the best I’ve heard.
- multi tracking vocals very easy to distinguish, backing singers had their own space.
50 ways to leave your lover track - kick drum, deep and well defined, again best I’ve heard.
- bass guitar, very tuneful and I wasn’t even aware of that before.
I can see why people would like this sound.
With the R in the fuse cap holder.
- dynamics greatly improved, sounded like I’d turned the volume up slightly, although I hadn’t.
- toe tapping came back, I don’t remember doing that above.
- all the attributes as above but bass not just so well defined.
Going on the principle that ‘loudest’ is the correct orientation I’m leaving it in the latter position.
So current flowing from P20 to fuse cap and SR on the fuse the current direction flowing in direction of P20 current.
Granted, I’ve made this decision on the basis of 5-6 tracks over a very short time interval.
Also, I’m in the UK so I don’t know if there are any differences between the US and UK P20 models.
I have changed over my UK mains plug to the Master fuse but haven’t tried it yet, giving the P20 electronics a little time to cool down. I try to avoid switching it on and off in rapid succession.
I’ll update tomorrow as to how the two fuses are working together.
First test, of course, will be the same 5-6 Paul Simon tracks.
As my P20 powers my home theatre system, including my projector, I’m looking forward to trying it out tonight.
Even without burn in I can say the internal P20 fuse will be staying.
One other observation, the AM-M1 fuse added a lot of ‘meat and bone’ or body, to the sound.
Now hearing the Master fuse I feel there was just too much body to all aspects of the sound.
The Master adds the appropriate amount of body to each part of the audio spectrum, bass, mid and treble so the sound overall is a lot more balanced.

Sounds as if you are on you way to a whole new level of experience…
The AM M1 does require some “cooking” time.
When I had my AM M1 in my P15 somehow I got in backwards. the mids and
bass became thicker, the highs just ok…then after some time…my lightning fast mind
a lightg bulb came on and flippe the Am M1’s orientation with the base of the M into
the fuse cap holder…
That cleared things up a lot. so much better…as good as the AM M1 is the SR Master
is way ahead of it…
Yes the AM M1 does adds meat to the bones and body …but in combination with the SR Master
vibrancy, speed all the good things remain even increase in quality…
As time goes by it gets even better…
Congratulations
Best wishes
A quick update on the Master fuse in my P20 power cord.
It brings the best of both worlds in that it gives the ‘cleaness’ of the Master fuse in the P20 the ‘wrong way’ but the dynamics with the internal fuse the ‘correct’ way.
I’m happy I have the correct orientation of the fuses for my system, now for the burn in period. It can only get better.

Yep you are in for a good treat!!

Haha, it reminds me of the two M-1 fuses. I had one in the “right” direction, and the other in the “wrong” direction.
Now I think it does not matter. Once it is all broken in it is ALL good!
Ja Ja ja…famous ast words uh huh…
Best wishes
I just had a disturbing discovery. The Purple in PST has the R insides the holder while BHK pre has the S insides the holder. I remember I heard them to determine which direction I liked better first.
I am not sure about this directional business anymore
