Hi Fellow Magnepan owners, I know this is going to be a firestorm thread filled with claims of snake oil. But I am always about trying to get every ounce of performance out of my rig and took the plunge on Synergistic Research Purple fuses. I'll get to the point and say they are amazing and worth every dime. My 20.7's are more open and even more detailed. I get the skeptics that don't believe a fuse can make this type of difference but to my ears it's undeniable. To me for under $600 its the best tweak you can make to your Maggie's, and that includes stands. I found the leaps my system has gone from since changing out the fuses provided the greatest difference by far. I heard nuances in songs that I never experienced before. Accuracy, spaciousness, focus and clarity were what stood out to me. The SR Purple fuse made my great speaker even better.

If you don't believe it, you won't hear it.
Life is hard. It's harder when you're stupid.
Again I purchased the VeraStarr mod which consist of four silver cylinders that act as the fuse replacement. The sound was glorious on my current and previous pair of 20.7's. However a month ago I had a voltage irregularity that caused my tweeter on the speaker to shut-off. I thought it was blown but later discovered I just needed to replace the cylinder with the standard tube. Once that was done the tweeter became operational. I then made the decision to ensure the protection of the tweeters and purchase the SR purple fuses. I honestly feel like they sound even better. Highs are more extended and clear. The reason I wont do a full mod replacement of the fuse panel altogether is that I have a 1 year upgrade path which could lead me to a pair 30.7's.

I've heard components without any anticipation of results and have been surprised on more than one occasion with what I've heard.
As for fuse topic, the best in terms of audibility is none . Many years ago, I bypassed the signal fuses in Acoustat 2+2s for a subtle improvement in transparency.
Yup
You can't even say that, because "best" is a subjective term. A different fuse might have some LCR characteristic that contributes to a better audible result for some people in some instances.
As I've said many times, subjective evaluation is beyond discussion.
You can't have it both ways. :)
Dave.

Who said anything about a "different fuse"?
The OP did. He's fuse rolling dude.
Fuse rolling means using different fuses.
I know it's difficult, but try to stay focused.
Dave.
Better to me Dave and since they are my speakers in my listening room connected to my gear I feel like I can say that they sound better to me. Doesn't mean it will yield the same results or opinion for you or anyone else.
Absolutely.
As I mentioned, if you note some beneficial aspects to the change, you gotta go with that.
I approach all of these experiments from an objective standpoint, but am smart enough to stop when subjective evaluation becomes involved. There's no more basis for discussion at that point.
Dave.
No I get where you're coming from and totally understand. I don't ever want to mislead anyone. When I say better I mean to me in my setup. I would never say a product is better because as you mentioned that is very subjective. I use these forums to pass along my experiences and what I find musically satisfying to me. Having these debates and sharing our experiences is what add to this hobby.

when positions are fabricated and have no basis in fact.
Let's debate what inmates actually post. You never posted what fuse was best. I never compared fuses, yet facts like that don't get in his way.
Instead of acknowledging reality, he doubles down and acts like a child. Go figure. ;)
Because you're ascribing a position to me that I never took. You see, this is one of the reasons I don't take you seriously anymore. Because you're completely incapable of focusing on a topic without drifting onto some silly straw man tangent.
You would make an excellent politician.
The reason I talk to you like you're a juvenile is because you are.
Dave.
makes no sense whatsoever.Perhaps you should quote actual posted content in your replies so that you do not become confused.
No *one* has posted what you allege. Only in your imagination. ;)

Got some results from double-blind listening tests? Would be worth doing.
============================
Science doesn't care what you believe.
just installed the copper tube by-pass mod
so far so good and it saved me about a thousand dollars a fuse
I had a very similar experience with their Orange fuses in a PrimLuna CD machine. Like very obvious change for the better.
Zero change noticed when I put one in my CAT preamp, and small, but perceptible change when I put one in my daughter's Jolida FX 10.
So, varying degrees of impact depending on the device for me.
I'm not here to argue the validity of improvement, cost or diminishing returns. What may be a waste to one may be a splash in the bucket to another. For my ears after 2 weeks of burning them in the purple fuse has made a noticeable improvement in SQ.
Based on my own experience, I completely understand and concur.
The improvement in the sound of that PrimaLuna CD player was undeniable.
And this was not my first rodeo with fuses. Been using them by different makers in different devices for probably close to 20 years.
I suggest to get some 0.25" copper tubing from Home Depot. (Refrigeration coil.)
Cut that into some 1.25" pieces and A/B test with your fuses.
Do that test blind with the assistance of a helper.
Check back after you done that. :)
Dave.
What about the simple expedient of removing the fuse and holder from the circuit altogether?
I make jumpers for my 1.6s.....which come with Chrome Plated Steel....(they ARE magnetic!) I replaced with lengths of #6 wire sanded to match the diamter of the original jumpers......
#6 is 0.162" and I think the jumpers are about 0.15Plus......
Too much is never enough
Yeah, that's an option.
But the OP, I think, is primarily interested in the audibility of fuses, or "fuses." It's important to establish an audible reference if going down that rabbit hole. Just replacing them with a shorting bar establishes that audible reference, without altering anything else in the circuit.
But, you must perform the evaluation blind, or it's meaningless.
Dave.
That's literally the VeraStarr mod with the exception of it being pure silver.
Yeah, I understand.
The second part of my suggestion is the most important part.
Dave.
that, for $600, you will hear differences. I'll bet that if you open up
your electronics and replace the internal fuses they have that you will
hear even more improvement. And if you replace the point to point wiring
in your electronics with different wire you will also hear some differences. If you listen to the same music at different times of day
you will hear differences. There's lots of changes you can make that will
make a (seeming) difference, particularly if you spend lots of money doing
so.
Life is hard. It's harder when you're stupid.
I agree with the time of day reference. I have a dedicated room with dedicated power and I've been using the VeraStarr fuse bypass tweak until it nearly cost me my tweeter. I immediately looked for something different. I've been doing this crazy hobby for a longtime and to be quite honest I've been sitting on this post for sometime now. The Purple fuses are the real deal and I don't know how the folks over at SR do it but it works and makes a audible difference. Some may call it snake oil or buyers allegiance which may be true. If so I'll take another bottle.
I put some ceramic fuses in the LRS for about thirty bucks - big improvement
the stock ones are shitte
a few on the tweaks asylum were talking about it and since it's a low power fuse on the order of usually less than 1 amp, it must be some kind of inductance wound on an iron former with a certain type of wire that will open at the current level needed. It will also filter higher order inaudible trash harmonics from the AC power line or speaker fuse.
I requested that an inspection inside would be nice if any of them had blown but never heard since.
Damn. I blew one of their cheaper fuses (a Blue, I think) in the little integrated I run on the AV system several weeks back. It never occurred to me dissect it. If I burn another one I'll see what I can do about an autopsy and report back.
The one that blew, really blew. As in kind of exploded. I mean, there was no drama or anything, but when I got it out of the holder it was blown out.
ok, give it a try next time. It might be at least interesting
