I think I have given the M1 plenty of burn in time and I’m not sure how much more they will change over time. So I went back to the SR Purple in my P20 and was pleasantly surprised that I preferred it over the M1. I wanted the M1 to sound superior on my system but it doesn’t. Have other M1 users noted a difference beyond 200 hours? Maybe I haven’t given it enough time? Not sure if it matters because the purple just sounds right to me.
Put a tuning ring on that P20 AQ power cord.
Play this song on both fuses. At 38 second do you hear a sax or a whoopee cushion?. A purple gives me a whoopee cushion.
Your beautiful FR30 speakers are very resolving for sure, and I do not know how they sound compared to the traditional speakers. They are on my list for future upgrades, but I need the stock market to go up a couple thousand points before the CFO in the house will even put them in her list, which has higher priority than mine.
One thing I found interesting is the latest Octave SACD mastering were recorded using this pair of speakers. The disc sounds remarkably different in my system from their previous releases. It sounded a lot more analog to me, and with extra richness. I mean the disc sounded like it has an absorbent sheet and M fuse built-in! So, I wonder if your system needs the absorbent sheet even. Of course, this is purely guessing on my part.
Hey Paul172…
I’m in the same boat…my first impression with the M1 was it’s warmer sound…yet detailed.
fuller bodied…
My preamp has been running a Purple all along…
Interestingly…after a good couple of weeks with 2 M1s in my system, power amp and P15.
So just for the fun of it…with the Purple back in my JC5 I experienced the same thing…increased
detail and immediacy…then I replaced the M1 in my P15 with the Purple…same results…
I was pretty giddy about the M1s initially…So it seems more tinkering here is called for…
What a merry go-round…I’ll keep you posted…
Best wishes
I’ll give it a try.
The elephant in the room with all these fuse comparisons and for all the component demos is the source itself. Each recording has its own sound. I have found this even with the Octave pressings which are on balance very good but are different In subtle ways.
Hey Vmax…
So purchased an mp3 …It is a remastered copy…
Listening with the Purples my impression…at the 38 sec mark are more an artifact of how
the sax was being played …a bit of a blatt on the sax; don’t think it was a whoopie cushion
poking fun. 
On Wynton Marsalis’ album Standard Time …the 1st track Caravan at about 1:37 or so in the
track Wynton cuts loose with a blatt on his trumpet…similar artifact as on the Sonny Rollins
track…Wynton’s blatt occurs regardless of fuse types.
Well…when the gumption comes back around will give it a go with the M1s…
Meanwhile I’ll just enjoy some tunes…
So enjoy the blatt from the sax… 
Best wishes
I gave this a try in both DSD and 192/24 PCM. I can’t say the purple sounded like a whoopee cushion but it does sound smoother and more realistic on the M1! Here is my latest M1 update and I’ll backtrack in case I left out part of this.
I reinstalled the M1 tonight the way I first installed it with the point of the M going inward on the P20. Saturday I flipped it so it was upside down and I did not like what I heard. I removed it and put the SR Purple in ahhh I like it! After this message I reinstalled the M1 as I discussed and put the point facing inward and I have to say the M1 is back in the competition!! I don’t know what I did differently but there’s a big improvement going on here. I will update again soon.
Was a dram or two of whiskey involved?
No alcohol involved. Maybe the fuse wasn’t sitting right but it sounds different
Could be whether the fuse holder was touching the silver solder where AM installs the filament wire. I always try to place mine so it will conduct through the solder.
I use this track for power cable evaluation’s. I say the purple is distorting those saxophone notes. It is really pronounced through my line array speakers. Those notes sound like raspberries like Sonny’s tongue was flapping on the reed. I am glad you could tell a fuse difference. @waymanchen11 mentioned distortions he heard in those frequencies also with the purple.
The Purple can be wonderfully clear, rich and powerful sounding, but with some recording with strong upper midrange energy, it can also be a little overbearing. Sounds like distortion to me. M-1 is more relaxed in those frequencies and sounds much better balanced overall.
No further explanation required.
There’s definitely a better sound now. First install of M1 to 204 hours sounded compressed. Reinstalled completely different. Shocking how much a little fuse can affect the sound.
I must installed the fuse correctly the first time then!
You found the one and only way to place the fuse in out of phase.
Fazers on fabulous!
Geez - is there no end in sight, the spurious doctrine and the enabling of others.
When I play my system I get lost in the music, I’ve no desire to alter anything, why shatter the engagement level. The amount of time you spend fettling with your system it’s in a constant state of flux. You’re taking this nonsense to subatomic levels. ‘Quarks for Quacks’
What about the endcaps on the fuses, the orientation of same, they’re both pointing inwards? Surely this must have a bearing on performance, sonically pernicious, taking it to the extremes that you do every 5 mins! Then there’s the depth of the lettering etched in the endcaps - could this change the integrity of the fuse and fuse holder? And one must consider the purity of the solder and density per fuse? …I’m just thinking out loud so please don’t try to offer me an explanation!!
That said, if all the flimflam makes you and others happy, then who am I to say!
The wrapping of copper conductors around a mains cable(s) outer insulation, including the IEC plug, still tops my list of your “deadliest” ill-founded contrivances.
