Synergistic Red Fuse ...


I installed a SR RED Quantum fuse in my ARC REF-3 preamp a few days ago, replacing an older high end fuse. Uhh ... for a hundred bucks, this little baby is well worth the cost. There was an immediate improvement upon installation, but now that its broken in (yes, no kidding), its quite remarkable. A tightening of the focus, a more solid image, and most important of all for my tastes, a deeper appreciation for the organic sound of the instruments. Damn! ... cellos sound great! Much improved attack on pianos. More humanistic on vocals. Bowed bass goes down forever. Next move? .... I'm doing the entire system with these fuses. One at a time though just to gauge the improvement in each piece of equipment. The REF-75se comes next. I'll report the results as the progression takes place. Stay tuned ...

Any comments from anyone else who has tried these fuses?

I thought I'd never post this but after almost two years after installing HiFi Silver Tuning fuses in my amp and SACD player, I thought I'd try out reversing the fuses in my SACD player. I was never in the camp of "correct orientation" of fuses but knew that simply using a better made fuse could improve the sound. Replacing them gave me a leg up on what was possible but I never could get the results I wanted. The highs were a bit subdued.

Still I resisted changing the direction of the fuses. 

Fast forward to the present: I've been on the lookout for a new pair of speakers that could satisfy my yearnings for what I'd heard with my ribbon super tweeter on my old Tonian Labs speakers. Eagerly I waited for the chance to hear the Elac Adante monitors and they almost had me. Reading up on the Tekton line of speakers got me interested in their monitors which used the patented design of the Double Impacts. 

It was after consulting Elliot Midwood of Acoustic Image and picking his brain that I came to the conclusion that it had to be my amp or SACD player since he felt that the Marantz had to be complicit in all of this as he's heard the very same drivers sound better, so it had to be in the application. He's been at my place and heard them and likes them very much but the highs were always a tad recessed.

Thinking it through, I drew down on the only possibility and finally took out and opened up the SACD player. Unlike the integrated, which had a fuse only in line with the AC, the SACD player had four fuses. Looking at the circuit board, I seemed that at least one of them was in the signal path: maybe two. I knew that there were dedicated power traces to the different DACs and clock. but having all four serving some kind of AC distribution didn't make any sense. 

I had originally oriented all of them to face the same way, using the logo as orientation. What I did was to flip the fuses the other way and give it a listen. 

Case closed.
 
I'm not interested in getting a new pair of speakers anymore. The highs are back, in spades. The soundstage is now permanently wider than my speakers. The center stage is now up, where it used to sag. The upper mid bass emphasis is reduced and tighter. I no longer use the treble boost as it adds too much. Flat is where it's at. Over two days I've spent about 12 hours listening to familiar recordings and all I can do is shake my leg and head in disbelief to the music.

I could care less to those naysayers who've yet to hear it for themselves. I care not to respond to them as well so go ahead and troll all you want. I am content. Now I can splurge on that new LG OLED on Black Friday for the same money as a new set of speakers.  God, I love this hobby.

My $25 PADIS fuses are already blue and as great as they sound, I'll pass on the SRs. 👍

I think you just hit the proverbial nail on the head. If someone has, let's say, whole house surge protection (i.e. at the fuse box) then it would negate the need for fuses, period. The same would go for anyone with surge protection for their components. Others here have done that already and like you, sing the praises of going fuse free.

An audio dealer who I live nearby told me a similar thing when I told him the benefits I got with aftermarket fuses: use a copper bar or just pullout the fuse holders and solder it up with wire and I'd be floored with what I hear.  And, that I"d never go back.

You wouldn't need a double blind, AB/X test. Just one system with fuses and another identical system without and then watch for the furrowed brows and angry retorts.

@almarg & @auxinput,

Yes, yes, yes, I understand the perils of doing such a thing but please, no 'Perils of Pauline'. 😄   I like both of you guys and just looking at what I said is pretty much summed up at the end.

No fuse is better than a fuse. So, taking things a step or two further, a better made fuse is preferable to a bog standard one.

Citing people who've done it with positive results is not an outright endorsement of doing it. Imagining a world where is can be done (and maybe shouldn't) doesn't necessarily mean I will do it. I could have said it better but I think I've posted here enough for one to see what I meant.
If not:
ignosce me, pardonne moi, vergib mir, perdoname

All the best,

@rauliruegas Thank you for sharing your experiences. Fuses will always be a contentious subject until someone can demonstrate to those who don't believe that they do make a difference. 

One would think by now that all here are on the cutting edge. In fact, we represent mainstream thinking, at best but at least we're heading in the right direction. 😀👉

On another note, I found at another site a discussion on fuses and Lloyd Walker (the Lloyd who makes the Proscenium turntable) recommends that people try aftermarket fuses and try both directions to ensure proper rotational speed in his drive motor. The point is, one can find highly valued perspectives on both sides of this equation and point to them that they support their point of view, so it all boils down to what you hear.

@willgolf,
Thanks for the update on the SR Blue fuse. For me, it's nice to hear that you didn't hear an improvement over the PADIS fuse since that's what I have and I'd need to replace 5 of them. 😩

I truly feel that these PADIS fuses offer real value not only over a standard fuse but easily compete with the other aftermarket brands and all at their $25 asking price.

Just let the PADIS continue to break in as I'm still getting improvements with mine. 

All the best,

@auxinput--Darn it!
I wish the four out of five fuses I have were in the amp and not my SACD player. The PADIS fuses made the biggest difference in the my source player than the amp but......

I've only had experience with HiFi Tuning Silver Star and PADIS fuses and in both cases, reversing them gave me much better sound. The HiFI fuses were in for almost two years and the PADIS fuses were in for only three days and in both cases, they displayed the same deficiency in regards to how they sounded: rolled off highs, an out of phase focus and a one note bass, among other things.

I was never in the camp in regards to directionality which is why I waited so long to do it the first time around. With the PADIS fuses, I immediately suspected they were in the wrong direction but gave them three days to see if things cleared up, but they didn't and reversing them improved things considerably. 

It would appear to me that hearing something amiss the first time around should at least prompt someone to simply flip the fuse. There will be time needed to break in but even at first listen, you should be able to tell.

I just came across a review of the SR Black fuse and one of their power cords over at Audio Bacon. Take it for what it's worth but the reviewer(s) ended up replacing all of their fuses due to the results they got. 

I know, it's all pay for play and they got all kinds of kickbacks and who can trust reviewers anyway and it's all a scam and everyone's in on it and they're all delusional and it's all due to expectation bias and they all keep jars of magic beans around just in case they need to go out on their unicorns in search of giants.....

@goose - I've replaced the four fuses on my Marantz SA15S2b SACD and got great results. I don't know how your's is configured but all you have to do is pop off the top and take a look. 🔍
