Synergistic Red Fuse ...

Ptss: I'm a photographer.  And, work in sales, but cameras, not audio gear.  The nickname came from people telling me I had a way that I blurred into the background, and captured great candids of people.  I call my my speakers my "mistresses", because I spend as much time with them, as I do my wife to be, who is also an audiophile, her name is Jocelyn.  She's a teacher, a brilliant artist, and loves music maybe more than I do.

So, on top of being blurry, I'm also very (wait for it...) transparent.

Have fun with that.

Wolf, I have no idea what they do.  If I did, I'd manufacturer my own, and save myself money.  The skepticism is healthy.  Well before to fuse craze started, back when I was younger and much poorer, I noticed that ceramic and glass fuses sounded different.  Stranger, still, different manufactures of glass fuses sounded different.  I don't know why that is, but it was audible, and repeatable.

Generally, I've stayed away from aftermarket fuses, even prior Synergistic fuses, because for what good they did, they also introduced some bad.  Outside of one lone Furutech fuse in my amp, everything's been stock, with whatever fuses came in the gear.  It seemed like a waste of money to gamble on change, when there was no guarantee that the change would be good.

This Black Fuse has no downsides.  Assuming you like your gear, and the music it creates, it'll just make what you hear sound more open, increase space and size while filling space better, with no change in tonality, and no spotlighting of any frequencies.

I understand the skeptic camp, and as much as I'd love to do an a/b test for any of you, I get the sense that you're more interested in being right than sharing the experience with me, and posting your own results here.  Knowledge is all fine and good, but what I've experienced with this fuse in place is running head first into what I know.  In that fight, experience wins.

But, if anyone would like to hear it for yourself, and live in the Los Angeles area, send me a private message, and I'd be happy to give you a listen, have you meet Jocelyn, hand you a beer, and whether or not you hear a difference, we can talk about other things like good music, what started us in being audiophiles, and they debt were hiding from our significant others pursuing it :)

Regards,
Jason

You make me wish I lived in LA Jason! Beer while listening to good music with music lovers? Nice. Like you I have no idea how these fuses do what they do.......nor do I care. I don't know exactly how most of my equipment works and thankfully that doesn't diminish my joy of listening to it one iota. Hiding the actual cost of our audio obsession from our significant others? Ignorance is bliss, right? :)

Wolf, I found this on another thread and it may (or may not) answer your question:

The idea that fuses and power supply components are not part of the signal chain is not entirely correct. Anything coming in from the A/C, power cables, fuses, rectifiers, regulators, or power supplies can all become part of the output signal.

An operational amplifier circuit (whether discrete or monolithic op amp) will only pass through the actual signal if the signal is coming in on the inverting input of the op amp AND the negative feedback gain is unity gain (0 gain) or less than unity gain (i.e. it’s forcing op amp to de-amplify the signal). In this case, the waveform signal will actually route itself around the op amp using the negative feedback line as a pathway. That being said, even with unity gain, the type of op amp or power supply elements will still influence the character or sonic signature of the audio.

If the negative feedback circuit is set to create a "gain" (or amplify), it increases the voltage of the waveform by using voltage from the positive/negative rails from the power supply (i.e. +/-15V). This additional voltage is sent through the output pin of the op amp. It this case, the fuse, power cord, A/C elements will contribute to the character of the waveform (in the sense of affecting how the op amp slews in relating to the input waveform, how far/fast it slews, character of the DC noise, etc.).

In a power amp circuit, the output transistors have to create massive gain (turning a 1V input into something like 15-100 watts or more). It has to use the A/C power coming in to create this voltage, so your signal is actually something like 98% A/C voltage.

I’ve posted that link before, but it’s an excellent lecture on how op amps actually work.

It may explain why some hear improvements and some do not. It's all over my head but it shows causality of sorts.

All the best,

An interesting comment:
"Oregonpapa, continuing to promote these things with silly nonsense is like continuing to try to ride a dead horse"
Or,should one say "a dead parrot"???  

Jason,
Wolf did try the Black fuses in his system and said it offered no improvement compared to his stock fuses. Very different experience from mine but I certainly accept his result. Different ears, room, components etc. We can only report what we hear.
