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?

I am looking to replace stock fuses with SR Blacks in my system.  I was thinking of ordering fuses with higher current rating than installed stock fuses for two reasons:  first, I understand that they could blow at a different threshold than stock fuses and are expensive to replace, and second that I have heard that higher current rated fuses sound better, which would make sense due to their higher current carrying capacity.  I wanted to ask people on this thread your thoughts and experience with this.  Typically, how much higher rating do you replace the stock fuses with?  eg, my Amp (ML27.5) uses 10A fuse, would you replace that with a 12A or 15A?  Any thoughts on this subject will be greatly appreciated.
Thank you for your inputs about the value and margin in black fuses.  I am now experimenting with the direction of these fuses. 

I have been told that SR fuses should be oriented such that the writing on the fuse is in the direction of signal flow (ie looking at the SR label on the fuse, arrow going from S side to R side of the fuse). 

For fuses on AC power line, I am assuming that AC "signal" flows into the equipment thru Live/Line/Hot terminal and out thru the Neutral terminal.

Thus, for fuses on the Live terminal of the input IEC power connector, the S side of the SR marking on the fuse should be towards the Line terminal of the IEC connector.  

For fuses on the Neutral terminal, the R side of the SR marking is towards the Neutral terminal of the IEC Neutral connector. 

Please let me know your comments and if this theory is a proper way to orient fuses.
