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 was on another audiophile site last night and mentioned that I was getting good results now that my new SR power cords have broken in. As a result, I was subjected to ridicule with the members saying that I bought into snake oil and that there is no difference in cables. I asked the main culprit to list his equipment. He has his speakers up against the wall and driving everything with a Pioneer receiver. Mid-Fi at best. He said that he had visited this SR fuse thread and thought it was all BS too. I asked him if he had come to that assessment after trying the fuses in his system. As yet, he hasn't answered. "Crickets."

Has anyone changed direction of fuse after going from red to black fuse....would seems that if one direction is better for red fuse that same direction would be better for black fuse.....

my amp is hard to switch fuses so would rather not switch several times

so far the amp when the black fuse is in same direction as red fuse seems to have better separation and air and soundstage but a little less wamth little less weight in bass weight....

Was reading about fuses and pulled out the fuse in my preamp but it was very hard to read, it definitely said 6.3A on one side the other side was much harder to make out but pretty sure it said 250ma. Do these numbers together make sense? Also how can I tell if the fuse is fast or slow blow? Sorry for the neophyte questions just never really looked at fuses before. Thanks!

Hi Jond,
6.3 amps is a very large value for a preamplifier  (must have a huge power supply ). My gut feeling would be slo blo. Are you able to get in touch with the manufacturer to answer your question?

@charles1dad  I certainly can contact them in the meantime took another look and its F6.3A on one side and 250ma on the other. Guessing the F is for fast blow but the numbers are what's confusing me as 6.3A and 250ma are totally different values are they not? I may be misreading the 250ma part the engraving is incredibly hard to make out its a .75 inch fuse. Thanks.
