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?

Nice!  SR has some really innovative new products. I'm looking forward to the upcoming Newport show where I hope to meet several Agon members in person.  Anyone besides Bob and David going? If so, we could set a specific time to meet in the SR room sometime on Saturday afternoon.  It would be interesting to observe SR's entire presentation.

"actually think it makes a lot of sense that the fuse is important as it is. The best way would be no fuse at all but can’t do that. So considering all power comes through that fuse, before i spend 1000 dollars on a power cord, I should probably take a look at the power fuse.."

Not to be repetitive but some reasons why the fuse is actually critical include but are not limited to it’s exposed to RFI, it’s exposed to vibration, it’s exposed to magnetic fields, it’s a conductor, thus purer and/or better metal conductors and end caps are audible. For starters I would specify 5 nines silver or 7 nines copper for the fuse wire, end caps and the fuse holder. It's not rocket science, folks.

I see my previous post got deleted by mods for using foul language.  Anyway, just wanted to say thanks for the suggestion Charles.

Bingo. From my own personal experience, it took a couple of days for the new fuses to break in while playing 24/7, just like any new cable or component. 

Now before anyone counters with how can something so small need to be broken in, think about all the discussion about capacitors, connectors, cables and the like needing some time to break in. This is generally agreed upon.

The act of removing and inserting terminations which removes motes of oxidation has been made to discount just what actually is responsible, as has extremely small matters as turn on and warm up time needing to be exactly the same, time of day, weather conditions, seating position, frame of mind, etc and yet some other thing as small as a fuse is to be discounted?

Gentlemen, you are arguing against yourselves.

All the best,

Hi Nonoise,
That's why I am glad there are two threads discussing premium fuses. One for the skeptical and this  thread for happy users of these fuses. This is good IMO , one side will never convince the other,  waste of precious time. 
Charles,
