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?

^^^ jwm ...

Glad you're getting the results from the SR Black fuse. Its a terrific tweak for a very modest outlay in cash. 

I only go to one show a year now ... and that's the Newport show. I used to go to CES in Vegas every year, but I've grown to really detest that place. It takes a week to get the tobacco smoke out of my sinuses after attending the CES.

The listening session last night was the best ever.  I have two more SR Red fuses to swap out for the Blacks. One in the phono and another one in the amp. Look out ... more improvements to come.

The SR black fuses (2) in my preamp and phonostage are burning-in nicely, starting to relax with each listen, just as you have been saying oregonpapa.

My system has ceramic drivers in the Coincident PREt’s and can present a bit edgy or harsh if everything is not just right, and they did a little but that is easing away and things are just opening up. Very nice.

I have tried flipping the fuses and the difference was clearly evident, also as reported by the pioneers on this thread. I had them in right from the start.

Thinking about two more for the scd-xa5400es now, imagine that.

I'm guessing I've got 80-100 of burn in on the Black that is in my Coincident CSL.  Tonight I did an A/B with the stock fuse.  Replacing the Black with the stock fuse made an immediately obvious difference.  Everything just went flat.  Very 2 dimensional, loss of dynamics, loss of harmonic richness.  Put the black back in and everything went back to what I have been hearing recently.  Amazing, how can a fuse do this?  I think I will be buying more.

Bill I'm glad that the Black fuses worked out for you,  I was confident they would be beneficial in your system. You'll likely experience further improvement up to the 150 hours mark. I believe that you'll be happy with these fuses in your Frankenstein 😊

Charles,

Charles,  I am thinking that getting a pair of 3 A slo-blo is up next.  Both the Franks and my HAPZ1 take 2 3A slo's,  so it is almost a slam dunk that one of those will benefit substantially.
