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?

Jond,
That's good to hear. Are you by chance using the Cerious Audio graphene power cables?

Charles I am using Graphene Extreme digital cables, analog interconnects, and speaker cables, but my power cables are all the previous generation Cerious Nano signatures. They were the very first power cables I truly thought made a difference and now have them on my DAC, preamp, and power conditioner.

I recently ordered a synergistic research black fuse for my sa11s2.  Finally got the lid off.  On the circuit board they have it labeled as a 1.6 amp fuse.  However, their was a 3.15 amp fuse in the unit directly from the factory.  So I will put in a 3.15 amp fuse.

It could be the difference in the amp is due to 120 vs. 240 volt options. Most stereo equipment these days is built for use world-wide so it needs to accommodate both voltages. 120 volts with a 3.2 amp fuse will deliver about the same power as 240 volts at 1.6 amps. The board probably reflects the amperage setting for the country where it was designed or manufactured.

Congratulation on getting the lid off the Marantz Sa11-2. That unit has one main power fuse and also 6 rail fuses. The rail fuses are 1.6 amp and 1 amp rated. The main fuse is the 3.15 amp.

Leave the unit on 24/7 for best results. Give the fuse a week to settle in.
