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.

All the best,

Congratulations on having the courage to experiment. I am glad you did this experiment because I had the same results in both of  my Marantz SACD players.

As fate would have it the arrows on HiFi fuses don’t indicate direction the fuse should go. In fact HiFi Tuning advises customers to try each fuse both ways to determine direction. It is an old wives’ tale that the arrow points in the direction of the signal flow or electricity flow. It’s also an old wives’ tale that the fuse should go in the opposite direction from the direction of writing on the fuse. The little diode logo or arrow is simply a way to help you remember which way the fuse went just before you flip it. This feature is especially useful if you accidentally drop the fuse with clumsy fingers whilst flipping it or forget which way you had it. This means HiFi Tuning doesn’t "pre-set" each fuse for direction. But HiFi Tuning IS AWARE fuses are directional, we know that for sure. All fuses. Even fuses in AC circuits. So the probability is 50% that a given fuse was inserted in the correct direction. Therefore the only way to procee when one has multiple fuses is to flip each fuse one at a time rather than all at once.

Happy 4th! Will there be fireworks here? 😀
Just wanted to thank oregonpapa for starting this this thread, and many others for participating and contributing. It has pointed me to many ways to improve my system, and increased my enjoyment of it greatly. I am truly amazed at how far it has come in a relatively short time, and this thread has played a significant part in that.

Really looking forward to hearing about the "mystery tweak" that oregonpapa is currently testing.

Thank you tommylion ... 

Since starting this thread, my system has improved by leaps and bounds. And to think, it all started with taking a chance on just one of SR's RED Fuses. I'm indebted to the guys at SR Their tweaks truly work and are transformative. This has led me into other area of tweaks, many of which, came at the suggestion of members here. I'm indebted to those members as well.   

On the "mystery tweak,"  It looks like the reveal date may be sometime toward the end of August. At least that's the latest info I have from the genius, who now has become a personal friend, that came up with the idea. I hope so anyway ... its just too good not to share it with all of you. As I said before, it addresses a major problem that has gone unaddressed before. It brings audio systems into the realm of true realism.  I think even the mid-fi guys will benefit. Those with high resolution systems will be completely bowled over. 

Nuff for now ...
