Vmax, an interesting thought. Would be good if someone contacts Audio Magic and asks them this.
I got my M-1 at the start of last week and have around 125 hours on it, what AM recommend.
I think I’ll give it a few days more to consider it fully ‘burned in’.
I configured my as you recommended earlier in the thread, with the V in the M pointing from the end of the fuse holder to the start of it.
… unless AM don’t make their fuses in a consistent manner, which is unlikely.
So, Vmax, you started off as with the above orientation, have you flipped it the other way now and found it better?
I’ve been giving the AM M-1 a spin in my Coda 07x since early Friday…I now have around 20 hours of actual playing time on it to date. When I first listened I was not very impressed with what I was hearing…that was within the first 30 minutes…but…after the initial 30 minutes…to my disbelief, it started to open up and strut its stuff some… Nice!
After another 3 to 4 hours (and still counting)…the change was quite inviting.First off the bass and midbass took on a new level of articulation and power. Not over the top but quite noticeable. Next up was a slight increase in width and depth of the soundstage… with notes being more discernible from within but without any edge or bite to them. I also felt a more relaxed overall presentation to the music which seemed more natural to my ears. Also a bit more air around the instruments giving a better illusion of the recording performance within my room…an opening up of the instrumental layering if you will. In the front to back and side to side plane… there was a very noticeable improvement of image placement. I noticed no increase in the illusion of height within that soundscape.
I will see how the next week or two pans out. If things continue to mesh… I may try 2 more in my #8…Overall, I like what the fuse adds to the overall synergy of my system! A keeper!
Oh…I did change direction once and there’s definitely a difference in its presentation.One way being more full and natural and the other way a little bit threadbare…but not overly so. I will check again for directionally in the future!
PS… I forgot to mention that there is also a big increase in clarity of sound throughout…I believe this helps in the imaging department…Very nice indeed!

More time should bring more goodness. I have about 200 hours now on mine in the P15 and there is just a bit more of what I like about playback happening. Sweeter treble, a bit warmer lower midrange, instrumental separation and a bit more depth to the soundstage.
I may well hang tight with just one M-1 and the rest Purples. We’ll see.

I find that is my case also. One way is a little fuller and richer sounding, but not by much. It’s so close, it may just be in my head.
Either way was good for me. Anyway I ended with the fuse facing this way. I’ll give it some more time and change it again and see what happens.

Thanks for the photograph.
Generally speaking, our attempts to describe the fuse directionality have been a bit lacking/confusing.
In the present instance, a picture really is worth a thousand (or so) words.
Cheers.

This link indicates Audio Magic fuses are not directional.

In two samples the sound is consistent with the direction stated. The second fuse the solder was rougher on both ends not ground as smoothly as first one. Perhaps that is what I am hearing difference since contact of conductive areas differ on surface with end contact.
My ears tell me different…And I know for certain it ain’t in my head…
I wasn’t saying that there wasn’t a difference. Just linking what they say.

I have mine installed just the opposite of yours…Your way is the threadbare position for me…Me thinks AM does not take notice of wire directionality. Oh no…say it isn’t so…

Then it must be random. One way did sound a little different from the other. It will be up to each person to try both ways and chose the one that works best for their particular system.

Ok, I think when they put the label on the fuse, they put in on without a direction, so it’s probably random. I just for kicks reverse the direction on my M-1 and I’m getting the same results. The sound got more tighter and leaner, so the direction does change the sound. I suggest people that get this fuse should try it both ways and see which they like more. Here’s a picture of the direction that sounds leaner in my system.

If I was a betting man I would bet you are right on the money. I agree…it’s best to judge for yourself.

I posted a P-20 regenerator tweak you got to try. This takes M-1 fuse to another level. Check out my P-20 tweak thread in power components.
Such solid images involves preload of your power cord in the P-20 IEC.

I’m going to give some love to the Purple. It is sound great in my P20! I am waiting for an M1 to arrive but till then I have not found any faults with the Purple. My system has never sounded better.

I liked that Purple you have now too; until M-1 king kicked it out of door.
I understand and I hope to pay it forward if and when I move on from it. Just letting everyone know the Purples are good! Lol

I guess I’m going to be that guy. 204 hours in with the M1 fuse which (I enjoy and like) I put the SR Purple in and I think I enjoy it more in my P20 on my system. I agree the M1 excels with vocals and soundstage but the purple again ON MY SYSTEM sounds better to me. I’m hearing more separation in the instrument’s the background seems blacker. The vocals are close to but I think the M1 has a slight edge there. I will continue to listen. I think the M1 may be too warm for my set up. With the Electrostats and the BHK 300’s my system may lean towards the warms side before the M1 installed.

Your evaluation differs from most, but I understand why. Two M-1 in the system plus the 3M absorbent sheet in P15 changed the sound towards warm side and emphasized the mid/low frequencies too much in my system.
I reduced the absorbent sheet size, and the sound is more balanced. But I still miss some characters such as darker background and clean/detailed sound. I will try to adjust the tuning rings to see if they will help more.
I wonder now if I should get another Purple instead of ordering one more M-1.
As a Purple fuse user in all my PSA products (having worked my way up the SR product line over the years) have to say I got curious about the M-1?
Interesting reading in this and the M-1 fuse thread,
It doesn’t seem top be a cut and dry fact that the M-1 is better?
Different equipment, different rooms, different ears of course.
Some repeatable differences keep coming up, some prefer the M-1 some Purple.
For me,
the fact some still prefer the Purple (and the much higher cost of the M-1) has settled me in happily staying where I am with the Purple.
Need another one now, for my DS Dac external power supply…good job its not overly expensive.
