Hey Stier2704…
With the SR Master in P15 and AM M1 fuse music is very good…just
that with the Purple I get better extensions…
In my case there is no incompatibility between AM M1 and SR Master.
Of course there is the “ymmv”…

Thanks Luca. That explains one 
of just a dozen exuberant exultations out of the box. There have been so many others only a few contrarians.
It seems most that hear any difference with a purchase get confirmation bias from crowd sourced reviews that is has to be the same level of goodness. Others are convinced it must be my system even when sound measurements show severe attenuation, and not look in the mirror at their setup.
I suppose if you have huge acoustic issues in your room not addressed, such as too much bass. Then a three dB or more removal will get you excited of a fuses performance. Oooh I can now hear such awesome defined bass. Most listeners can’t hear a half dB frequency difference so many OEMs spec there. Some of the best use 0.25 dB. During speaker set up a 0.5 dB difference can and does cause images to jump sides or out of the middle on certain frequencies or instruments .
This is why I use room DSP. The audio purists who say equalizations, they do this and that to the pristine analog signal. They are so used to playback that is hiding details and not hearing what is really in the source. They think they others have to be missing some sort of magic when DSP is done right. If you’re system is set up well, and you have spent the time snd money fixing acoustics with treatments and DSP and you make a change like a brand new Master Fuse attenuator that shaves of 2.5 to 3 dB. Everything gets wonky to the ear and quite literally, is totally unlistenable.
So for all of them, yeah it must be my system and look here I made just one change. A Master Fuse that when measured shaved off 3 dB. No I am not a card caring ASR member, just affirmed with measuring what changes did and what I heard first. But still some could think, I must be out of mind and not know what I am doing or what I am listening too, or what good sounds like.
In the end though we are all right. None of us hear the same, nor is our systems or rooms going to be the same. That’s what is great about being an audiophile. We all have personal choices we make out of our individual paradigms (our systems and rooms ) and how we spend dollars in this hobby. I don’t flip equipment on grand scale but have discovered small things a fuse or piece of RF EMI absorber or piece of Sorbothane can have huge impacts on a system. Yes it can be heard and measured at the room and system level more so than taking measurements at the components and arguing it must be bad at components level. Since it was just a fuse with a rating and a wire.

Hey Vmax…
Without having read any “pro reviewers” review on the SR Master…
Bought one to check it out…You have read my thoughts on how good
it has turned out to be for me in my system.
The same for my new Furutech FPX Cu wall outlet…no reviews on it…
Just Furutech’s description…For me so far a product well worth the
price of admission.
Just a positive expectation of good…it works!!

Don’t worry Vmax, I bet we will see soon a new fuse (and I bet I’ll be one of the.buyers as usual). My journey in audiophile world has just started, I need to learn a lot more before reaching a few veterans like you Al, Vince and many many others.
Different opinions, different tastes, different experiences… can elevate my knowledge, and most of all I’m enjoying so much this hobby and music!
Have fun and thanks!

You should always be open to new things. That’s why such a forum is there to learn from experience and failure of others.

Hey guys, need some help over here. Finally pulled the trigger on a SR Master fuse (arriving next week) to throw into my Weiss DAC501 when I noticed that there is not one but TWO fuses in the fuse holder.
Firstly, does this mean I have to buy two Master fuses to get the full effect? I’m hoping this is not the case. I could maybe swing a purple since the two are supposed to have a nice synergistic effect together. But would I be okay with one?
Secondly, which way would you recommend I install the fuse and which side? I attached a pic in which I numbered the fuses with an up and down arrow.
I feel like two fuses add a whole new layer of complexity to this. Any help would be appreciated!

Has anything changed in the meantime with the SR Master in your system? Not that it’s defective. It’s weird that it sounds quieter. I also bought my Masters in the Netherlands. Perhaps it will already be brought in by Dutch wholesalers. It took 14 days to deliver even though it was in stock. It immediately sounded better than my run-in purple. The price has now been increased to €649. You would almost have to presuppose such a service for that. Only 2 people had previously reported that the Master sounded bad for 50 hours or the first week. Perhaps the fuses are partially retracted. Or are returns 
Hey roachbot…
Welcome to PS Audio forum…
Unless the fuse holder has only 1 active fuse with the other being a spare,
check that out first. If indeed it is 2 active fuses…you will need two Master
fuses Ouch!!

You need two. I was sad to find the same thing when I swapped an M1 into my Gryphon Ethos. Double the fun!

It looks like it is 2 active fuses… I’m going to curl up in a ball and cry.
If I used a Purple would that be so bad?

You may be the first one to try that, I believe.
If the DAC is both 110 and 220volt capable. Some manufacturers would use two fuses and switch to flip. Thuse with double rating in amps is for 11 to 220volt the smaller fuse is 220 to 240 volt
So check amperage and if one is double. Buy Master fuse to what power voltage you utility provided.

If they are same fuse amperage rating get out check book.

I would take a look and see what the 2 fuses are for. If there is a fuse for the left and right channel, the same fuses must be installed. If there is a fuse for the analogue and one for the digital section, different types can also be used. It is important to find out what two are there for.

I did gym last night. Listening to TV an hour there was no bass and image was poor. Will listen and measure frequency response to see if master is changing attenuation. The put in stock fuse listen and measure. Then go back to Master fuse burn in

The PS audio DS I DAC has two fuses one says analogue one says digital. But only digital fuse is used. Though they oulste a fuse both sides. Buying teo there is a waste of money. Do call to manufacture r or email to support. Where they may tell you warranty is voided if you switch.
