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 think besides the increase in conductive surface area a magnet helps focus the electron field so it is less random and becomes more organized. Like the electrons that leave a cathode in a picture tube they may leave at different angles but can be adjusted with a magnet or as an electron lens. The magnet may bend the electrons towards a common point."

What difference could bending the electrons or electron field make since the electrons are barely moving through the wire? Besides electrons are moving back and forth in an AC circuit, like in the mains fuse situation.

Tom also wrote,

"For me magnets also appear to focus vibrational energy over a given surface even one that is considered a non traditional conductor. They make for a more dynamic and organised presentation. Results in better sound."

It sounds like you are saying vibrational energy is good and therefore the more the better. Why not just employ a shaker machine? That would produce all the vibrational energy you could desire. I’m not sure I go along with you that vibrational energy is subject to magnetism. Wouldn’t the "vibrational energy" have to be uh, magnetic?

cheers


When the electrons direction are bent by the magnetic field then they have a shorter path to travel across the conductor.

Some electron microscopes use a magnetic lens to focus electrons.

Vibration can generate electricity that can react to the magnetic field.

Musical instruments generate large amounts of vibration..hear that.

Tom: "When the electrons direction are bent by the magnetic field then they have a shorter path to travel across the conductor."

The electrons are not the signal. Why would a shorter path for electrons improve the sound. Besides the electrons are moving back and forth as I already said. Their effective path distance is zero.

Tom: "Some electron microscopes use a magnetic lens to focus electrons."

But electric microscopes are not audio cables. How would focusing electrons change the sound, assuming for the moment magnets do focus electrons. The electrons are moving only a cm/ minute.

Tom: "Vibration can generate electricity that can react to the magnetic field."

Really? Example?

Tom: "Musical instruments generate large amounts of vibration..hear that."

Are you saying musical instruments are creating electricity?

"A friendly reminder to all that replace fuses in their equipment to remember to turn off the equipment before replacing the fuse. I do not know why but changing the fuse recently with a different fuse resulted in the new fuse blowing. I would guess it was a current in rush situation but on a solid state piece of equipment. So turn off equipment - replace fuse - turn on equipment. "

Better advice is to unplug equipment before changing the fuse.  Many pieces have a constant draw of power to keep some circuitry "warmed up".

Thank you for the reminder that to insure that a component has no active circuits,  it must be unplugged and not just turned off. Hey that's just what they always tell me to do at the computer "help" site after putting me on hold for 30 minutes!

Well the replacement Black fuse is in place and now has 75 hours on it. What a nice improvement over the back up Isoclean fuse. I am listening to Harp music to unwind after a stressful day. The shimmering harmonics of the plucked strings resonating with the body of the harp is most relaxing.

The plucked leading edge of each note is sharp and forceful, and then the relaxing full bodied complex decay of the note takes place. All this is occurring  with a jet black background and with a soundstage depth of a medium sized concert hall. Really quite remarkable.

An upgraded audio fuse has made this long stressful very hot day turn into a most satisfying and reinvigorating music listening night.
