Hi Vmax, thanks for the very comprehensive answer.
I understand your desire to move forward gradually in the tweaks… Regarding the Furutech Boosters, they dampen and generate negative jobs… which may be too much for low intensity electrical signals.
Regarding the Elite cable, it will be with Furutech NCF connectors and as I am going on vacation and staying in the region for work, it will be connected at the beginning of September.

Now that the M1 has full broken in (200+ hours) in my Marantz Model 30 integrated amp, I gave my system a serious listen. I’m definitely hearing more transparency and detail. Not a paradigm shift, but a welcome incremental improvement. I’m not hearing any changes in frequency emphasis.
I installed the fuse with the top of the M pointing toward the interior of the amp. I just tried flipping it around. It sounded a bit less detailed, so I flipped it back. As some have suggested, the label might be put on randomly since the fuse does not have a stated direction to it.

Which fuse did you replace before?
I have a Purple in my PP 3. I’ll say more about that in the other thread. 
I attempted to get to the fuse in my Marantz SACD 30n. When I removed the top panel, I found it obscured by a circuit board. So I removed the left side panel. Still no luck getting to it. 
PSA is a lot easier for sure. Good luck.

m-1 Fuse observations. Having been running the Multiple M-1’s With RF absorber tuning rings on the power cords that also have sorbothane isolator/ damping under them. i had an observation. Nearly every recording even old Analog there is a live sounding noise floor ee sweet spot. The older ones the illusion falls awys when one pushes he volume. Still good but back to recorded artifacts. The best stuff seems to have the widest volume range sweet spot of live music illusion. As if there is no limit to listening space acoustic issues kicking in. One can just keep pushing volume and dynamics have what seems to be no limit.
So far best tweak ever to stop limiting your music by recording quality since perfect volume is never illusive and there are fewer reasons not to explore depths of your library. It is the most liberating tweak to reconnect and not limit.

I have not listened to my system in loud volume for a while until today. With the third M-1 the music is more live-like than ever. It was in the system for 6 days and it needs less time to break in than my first two, but more likely it blended in with other two in a very coherent way, so I heard a more balanced sound without noticing any issue.
I have not adjusted any tuning ring position yet because I like the sound better than before already.

Please remind me where you put the M1’s.
Thanks
Ha! That could have a profound influence on how happy it makes him…

The first M-1 was in the generator, and this is where you should start. The second went into PST and my third was installed a week ago in DS. I left the lone Purple in BHK pre.
I will post a review of the 3rd shortly.

Thanks, I put one in our P20 3 weeks ago. I was thinking I’d do the Pre next. I like to make changes to the gear that has the most effect on my entire system before I start to do the “endpoints” like the DS, Rendu, etc… I figure everything in the 2-chan and the HT chain can benefit from the P20 and the Pre.
Thanks!

I’d LOVE to install M-1’s in my Ps SACD Transport, May KTE Dac & May Serene Pre, but $900 AND the 3 S.R. Purple fuses cost $600 and now get trashed for the M-1’s.
Oh well.
You cannot go wrong with any combo of M-1s. I tried the PST, DS and BHK pre from the 2nd M-1, but with the AM Ultimate Premier in the mix I ended up putting it in PST.

You will get a little discount from The Cable Company. If you have Purples in the system, even one M-1 would be beneficial from my experience.
Yes, I deal with Jason there and he discounts a little, but being a Senior on a fixed income I hate to waste money unless it’s gong to be 100% guaranteed sonic improvement.

Completely understandable! There’s no end of upgrading and one day a new fuse king will show up, and M-1 will flood the used market. Hope it’s not too soon for my own sake.

Has anyone discussed the sound (effect) differences between the M-1 and the Ultimate Premier (or is there a post or two already)? I’ve found the Ultimate Premier to be like some tubes: it takes over the sound, almost no matter where it’s put in the system. And its sound is somewhere between “alive” and “live,” depending on location inserted, but my sense is also that it is a little what I call pitch-elevated, i.e., not quite right. That’s very different than the UP’s predecessor, the Ultimate. It’s in a system that includes some SR Purple and Orange (both on the warm side), and QSA Reds (super, slightly warm).
I think it was discussed in the Purple Fuse thread when we jumped on the M-1 Bandwagon and Hijacked it.
I noticed the M-1 not only has more details but also sounds more neutral than U.P. I will post my review of the third M-1 tomorrow. I did not hear much difference tonight from yesterday, but I will give it one more day of break in.

I have had my third M-1 in the system for one week and there is no need to wait for more break in because there has been minimum change in sound for the last couple of days.
M-1 and Purple are clearly in a class by themselves. Both provide a ton of details and clarity. However, M-1 sounds warmer than Purple, and M-1 has a clear superiority in tonal density and musicality that surpassed any other fuse in my system. At first, I was worried about three M-1 may give too much mid/bass warmness, but it turns out the culprit was the AM Ultimate Premier. After I replaced it with the M-1, the sound turned to more neutral on the day and kept improving. Now I hear more details, fuller, and better tonal color in SQ than ever.
In my system, 3 M-1s plus a Purple worked exceptionally well. The cooler Purple plus warmer M-1 gives a beautiful timbre balance and weight. I therefore imagine any combination of these two fuses in the system is better than with just one. With two or more M-1s, some systems would get more benefits than others. My third M-1 is contributing better SQ to my liking, but its sonic characteristics were enhanced to a lesser degree from the 2nd M-1 (the second was less than the first also).
Once I become more familiar with the sound, I will experience different tuning ring locations to see if any tuning is even needed. As of now my system has never sounded better.
