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?

Fuses - all fuses - have been measured to have lower resistance in one direction than the other.
Please post links to proven scientific data on this, not just hearsay.
Maybe old fuses that have had many switch-on cycles put through them, sag and get carbon build up, even then it’s doubtful. (see 5 different length of times same fuse, ageing over time first link)

For anyone worried that your old fuses have been subjected to too many switch on/off surges.
"All potential fusers need to remember that fuses deteriorate with age from switch on surges (as pictured), and they just need to be replaced with good quality $2 fuse of the same value, as Almarg linked to.

GeorgeHiFi, were you sleeping through class again? The fuse information has been discussed many times. The HiFi Tuning web site contains the independently measured voltage drop data for all types of fuses, both directions, including HiFi Tuning, stock fuses, other aftermarket fuses, cryo’d versions of those fuses, glass fuses, ceramic fuses, fuses in DC circuits, fuses in AC circuits. To summarize the results of the fuse data: all fuses measure differently depending on direction of the fuse in the circuit because the fuses are physically and electrically, uh, directional. And if I can be so bold, that is why they sound different depending on direction. Wake up and smell the coffee.

They don't actually sound different, they don't actually sound at all. Fuses are utterly insignificant relative to the primary tone shaping components of any hifi gear, but seemingly can shape the tone in one's imagination if the listener really believes they do and spent enough on them. They're fuses…I say let them be as it's sad enough they're trapped in a little holder away from the rest of the more important bits, simply called upon from time to time to kill themselves by melting in an emergency. *sniff*…Hat's off to those little guys...

They certainly won't sound different to those who cannot hear.
