I think an SDFB is intended for components with only one fuse. An SDFB could also be an option for devices with a larger primary fuse that is replaced with a Sluggo. The smaller fuse values would still have to be protected with fuses. Those who have components with only one fuse can be lucky. My mono amplifiers have a dual symmetrical design and have different fuses for the positive and negative paths. Including a fuse for the control and display. A total of 7 fuses for a mono amplifier. The company EFuse in Germany has an electronic fuse solution that can be installed internally.

After 5 days of break in of silver sluggo with3M AB7050HF l ainpulled the absorber grom sliver.
Everything mushy and the highs lost without 3m absorber. It was nice but weak. So time for smaller piece.
Another OMG tweaking moment

That’s enough silliness for me. This topic has gone Full-On absurd.

No 3M material for me, it goes really weird with the silver. Have you tried both directions on the Sluggos? I find them very easy to discern a preference one direction or the other.
My third (and last) SDFB arrives tomorrow–going to be used with my DSD DAC Mk II.

Thanks @scotte1
It wasn’t Paul M that I was corresponding with, however the avoidance of sluggos is clearly the safer position for the company to take.
I suspect I’ll end up directing my interest in the SDFB to my P20 and perhaps DSD Mk2 & preamp. It may be a toss up between SDFB and Fidelium XLRs! My left BHK300 is no longer running off the P20, as I opted for longer XLR and shorter speaker cables (Fidelium).
I have not flipped silver yet but will try that next. But less 3M material really lit up everything. I guess i should rerun the B4Mac optimal room correction, then see if it still sounds livelier. I am really liking the small piece of absorber in the center of the hollow silver suggo.
That material just introduces too much treble or futzes with the tonal balance that way for my room and system. Without it is better for me. (I don’t have a treated room, and my taste has always been to a ‘darker’ sound than many others).
And there’s the ribbon tweeters in my directional/omni-directional speakers—they are very revealing and I listen to predominantly non-audiophile recordings.

I have to agree with aangen. This is getting so far out in left field. First off the power passing through the fuse is AC. Secondly the sluggo’s are solid pieces of material thus another reason to believe that there is absolutely no sense in thinking that they have directionality and also break in.

John, I wholeheartedly agree. Beyond ludicrous!

Believe all is ludicrous if you wish. My ears tell me otherwise.
Placebo effect is amazing. Only valid if testing does not allow you to know the conditions until after your judgement.

I’d invite you to try one before being so dismissive and snarky. I’ve gone back and forth and am confident in what I am hearing.

My wife is my secondary. She has no idea what the equipment does, let alone what I might be doing when changing from one thing to another. I just do something and ask her what she thinks after we listen to some music. I never tell her beforehand what I’ve done or comment on what I may have heard. If her opinion is a reasonable reflection of what mine was (without her knowing in advance), then I can feel more confident I haven’t fooled myself. It always helps to have another set of ears willing to participate. Some changes are more obvious than others.

especially if the ears are either side of a pretty head.
Oh, all this brouhaha over a sliver of metal. Oh please.

I was very skeptical myself. It has proven to be the most effective change I’ve made to my system in some time. In my case it’s not just a piece of metal but the fuse box as well, which is very confidence inspiring.

I am with Lonson. To me SDFB made a bigger positive impression than any of the fuses that I have tried (I have tried many). It reveals what my system (or any) could potentially do without the restriction on current flow.
I will be very surprised that an audiophile with a decent system cannot hear the difference. Regarding sluggo material, does one believe cables with different material sound different? Look at Iconoclasts cables then the answer is clear. Therefore different sluggo will sound different too.

As with many things audio a new product is introduced and a few try it. They are impressed.
Others reject it outright.
Over time, we learn the new product is beneficial ; e., g., interconnects, power cords, etc.

My comments are not meant to be snarky nor do I feel that the SDFB that does not make a difference but when it comes to solid pieces of metal have directionality in an AC circuit and that they require break in just pushes the claims beyond reality.

I feel the same about fuses. I can’t remember ever hearing a directional difference. But so many folks do that I’m open to believe that my expectation bias (it’s current that alternates) gets in my way.
