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?

Yes:
I absolutely agree the Synergistic Research Black fuse gives the most dramatic change. If I was just trying an audio grade fuse for the first time , I would absolutely audition a Black fuse first! They are that good.

I must also say, the improvements going from Red to Black in my Maggie 3.6R's is profound.  The music is sweet and clear--more listenable all around, and only about thirty hours in.

Regarding the SR Black fuse morphing with break-in, even installed in my REL sub the higher frequencies became harsh for a time and then we went to the "bass all over the place" phase as well. 

As a result,  I was also moved to put micro fiber towels into the rear ports of my speakers which are, of necessity, rather close to the front wall. Oddly, I was also moved to simultaneously turn my REL down a notch in volume. 

Patience during break-in is rewarded by the sound I'm currently experiencing--smooth, liquid, detailed and extended. Might be time to bump the REL up a notch. We'll see. Sounds fantastic right now...

andynotam:

A nice summary of what to expect when putting the Black fuse in a self powered sub. I experienced much of the same you have so nicely described. After two weeks the fuse was fully settled in and the music had a better flow than the sub with a stock fuse.

It is worth the effort to upgrade the sub fuse to a Black fuse.
