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?

Lol.  I never thought of that.  I actually meant the direction that it is currently in. Which I believe r on the side of the transformer and the s on the side of the power cord.

That’s the whole issue (with SR fuse directionality) in a nutshell. According to the post by the Synergistic Research guy that I quoted earlier, the letters on the SR fuse are simply to be used as a guide for remembering which direction the fuse was in just before you reverse it when auditioning the fuse for directionality. In other words, the letters on the SR fuse do NOT indicate the correct direction in and of themselves. At least that’s the way I interpret what the SR guy said. Ergo, it’s only a coincidence that your fuse is oriented just the same as his. To state this another way, SR doesn’t mark their fuses for directionality as does Isoclean and HiFi Tuning. If SR fuses were marked for directionality why would you have to try it both ways? The only reason I can think of is it's in case they marked it wrong.

David ...

Please keep us posted on the SR Black wall outlet as it goes through the break-in process. Interesting stuff. 

Thanks ...

I also happen to suspect, speaking of fuse directionality, that in the particular case of HiFi Tuning fuses it’s quite possible that the symbol that is printed on the HiFi Tuning fuses which is technically not an arrow but a diode symbol is strictly for keeping tabs on the fuse direction so, like the SR fuses, it’s a way to make the fuse cosmetically non symmetrical. Thus, like the letters on the SR fuses, the diode symbol on HiFi Tuning fuses does not indicate the direction that the fuse should be inserted in the component. This method of easing the fuse direction audition process would have the additional advantage for the manufacturer since he would not have to worry about keeping track of the wire’s directionality, which of course is the whole issue - the wire.
