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?
Admittedly I was skeptical about what a little fuse, which I remember buying for a nickel a pop in the old days, could possibly do for sound quality. After following all the fuss here, mostly positive though paying close attention to the persuasive `cannot-make-a-difference' minority, I went ahead and ordered one for my Sony HAP-Z1ES server and another for my almost new integrated amp (Absolare). What’s to lose, I reckoned, we can’t know what can be known if we fail to experience the unknown, and I’ve frequently discovered that technical truisms do not universally tell the tale (after 30 + years in this game, I don’t believe that everything can be measured, our ears need to play a primary role in the final analysis).

The amp already has a Synergistic Red, so I will not bother changing to the Black until it is thoroughly broken in, and further to ensure I limit the system changes to one thing at a time. So, with just the one Black in the Sony, my first reaction was… way, this can’t be happening! When I slowly recovered my senses and pulled my jaw off the floor, I reasoned that reality can play tricks sometimes, though my next 6 listening sessions told the same story: Increased texture in the bass, more gravitas to the overall sound, more pop from silent-to-loud dynamics, and a seemingly more relaxed yet just as detailed sound.

This after a week of listening, pretty amazing for a lousy fuse. Do I think it’s worth the price based upon what I’m hearing? Yes, I’ve encountered quite a few equipment/tweek upgrades that disappointed comparatively. Expectation bias? I don’t think so, I had no expectations one way or the other except to have an open mind and to keep the boxes intact in case I needed to return them. We shall see if other improvements (or indeed any negatives), reveal themselves in the coming weeks, but so far I am impressed.
Interesting butler. How did you change the fuse on the 
Sony HAP-Z1ES. What value did you use?
Hi PTSS, there are actually 2 fuses in the Sony, both are Small (5x20mm), 3.15A, Slow-Blow types.  I only replaced one of these, after a discussion in this thread back in October with Brownsfan here:
Welcome to the discussion, butler. 

As you continue upgrading to the Black fuses, you'll get a similar improvement as you have already experienced. They'll be a nice improvement when you change out your one RED fuse for a Black one too. 

Thanks Frank, it's always a nice surprise when we discover things that we never knew were missing, especially if one loves music.....and of course the music should always be the end priority but with the recognition that even better illusions of real flesh and blood performers in our respective listening rooms can be realized.
