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?

"If you Buy the new black PC you receive a SR Black fuse for free.Same for the Red. Nice Deal."


SR sure knows how to up the ante. If I was not happy with the power cords I already own, I sure would be tempted...

Can changing fuses have an effect on warranties?  Sorry if this was mentioned already. Thread's kinda long to search.
Always check with manufacturer! My equipment is not under warranty so I do not worry about that possible issue . Having said that, If I screw up my equipment- I am the one to pay the bill. I believe that the Synergistic Research fuses are safer than the 10 cent fuses. My systems now have a total of 22 SR-Black fuses.

OMG!

The SR black fuses (2) just went in the kit cold from the post box, about 30 minutes warm up, and I que up the first record, Susanne Vega Close-up vol.1. Between the fingering of the guitar, the bass line, and her breathy voice all are more vivid (than with the stock rat shack fuses), no question.

She may present a bit raspy and not quite as ethereal, or liquid, the performance at times may sound a tad confused, which should resolve over time. Now I haven't tried flipping the fuse orientation yet though, so we'll see about that. I look forward to these, very much, after adequate burn-in time.

Fortunately my preamp and phonostage are hybrids and though the signal path is tube driven, the power supplies are SS and basically never get turned off, so the fuses will see current without a need to run the tubes (or my ears) for their entire break-in period.

Does this sound about right on first blush gentlemen?
^^^ Yep, just about right r_f_sayles ...

The Black fuses reveal their promise right from the initial installation. You are most likely noticing a hard edge to peaks, strings and higher pitched instruments like flutes. In addition, the music just doesn't seem that involving at first either. As they burned in in my system, the fuses just seemed to open up from one listening session to another. At that point all settles in and the improvement from just a fuse swap is quite an ear opening. 

Please post your results as your two fuses break in. Thanks ...
