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?

Al, right you are...again! Thanks!
The resolution on my photo was not good enough to make out that 5A Fuse on the top line, but you are correct, it is clearly legible in the manual once zoomed in. So it is a 5A, not a 3.15A Slo-Blow

That seems pretty high for a preamp, doesn't it?

However, this still does not tell me if it is a small or large fuse. Anyone?

Thanks Al!!!

@jmcgrogan2 5amp doesn’t seem that high, my own preamp, an older Deja Vu Audio pre took a 6.3 amp fuse! I would hopefully assume our preamp’s both have robust power supplies! :-) Not that I know anything about such stuff really.
