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?

And now, try the Black!!! Great in every application except for a PS audio regenerator, especially the older P300, P600 ones. They tend to like the SR Red. See my thread with Jtubes2 on Synergistics Black fuses and Black outlets. And both of us have had Black fuses for at least 4 months, and no blown fuses, so can't speak to others' experience of the fuse blowing.

Hi gbmcleod,

Alexa6404 asked a question and we answered it...at least Al did.

Best to you,

It's possible that SR fuse is affected by the turn-on sequence.  My Pass XP-15 phono stage has no on/off switch.  It's powered on once the AC cable is connected.  I blew two Red fuses before I successfully used a Red with higher amperage rating.

By comparison, my PS Audio BHK amp is less likely to blow a fuse because it uses a lengthy turn-on sequence.  I'll know for sure when my Black fuses arrive.

I also agree that some fuses are directional.  I tried an Hi Fi gold fuse in my BHK Preamp.  In a single blind test, my wife (who's a musician with better hearing) agreed that one direction was pretty good, while the other was quite harsh (almost unlistenable).  This is a surprising because I never thought that it would be so obvious.  We'll try the same test with the Black after the burn-in.

Exactly the same as my Ayre K-1xe phonolinepreamp/power supply where I lost two 1A Black fuses before going to a 2A.

mtseymour,

Have you replaced all the fuses in your BHK amp with the black fuses?  How much better is your BHK after replacing the 4 rail fuses compare to the 2 main ones?  thx.
