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?

" That’s precisely why I have taken the steps to eliminate fuses from my system, actually to also eliminate and bypass the house AC entirely, as well as eliminate power cords, electrical ground, wall outlets, interconnects, transformers, large capacitors, crossover networks, room interactions, things of that nature."   

geoff. How do you eliminate all those things short of having an acoustical band/group playing for you...in your home, at your own whim? Please enlighten us.

"Everything is relative."  A. Einstein

Before you changed fuses most likely you were not particularly aware of any distortion, either. It's all relative. Trust me, you still have distortion.  Of many different types, if I can be so bold to add.

All systems have some form of distortion to some degree since none are perfect.

The first basic trick to good sound is to minimize noise and distortion especially the more offensive kinds.

Fuses are low in the food chain in terms of their overall impact on noise and distortion compared to most of the other usual suspects.

If someone hears a difference with a fuse or other similar RELATIVELY minor tweak, that is probably a good indicator that most of the other bigger more common culprits are in check. Or maybe the original fuse needed reseating or had some other issue that the change fixed.

I don’t see how anyone would object to calling a fuse a relatively minor tweak on e the grand scale of things, but I suspect some will. IMHO YMMV and all that good stuff as always.

Regarding fuse ROTATION... I have found "DOTS DOWN" to sound the best.

My Marsh power amp has two fuses per channel. When I initially installed the black fuses, all four dots on the fuses were facing up.
Yesterday I rotated them so their position was changed 180 degrees.

My first (five minute) impression was positive, and I was not motivated to change them back.  Eight hours later, during a longer listening session, I was feeling the way I did when I heard the improvement from the fuses for the first time.  But the sound was even better!

My cd player has a single fuse and I am pretty sure I installed it the same way.  The mains fuse on the Marsh is screwed in to a barrel...
I guess I could also rotate it and check for any differences.

I encourage everyone to experiment with fuse rotation!
"DOTS DOWN," for me!

Mapman, 
I agree and have said  (along with others here ) that the more highly resolved (finely tuned ) the audio system the more apparent the impact of the Black fuse. Thus their effect is greater than what one would assume a fuse can contribute.  In theory a minor tweak,  but much more in reali
