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?

Gentlemen, I need your help.  I can't tell if I need a slo-blo or fast blo fuse for my Line Magnetic Dac and 518i integrated amp.  I had previously replaced the originals with Chinese AMR fuses.  Very cheap but quite effective.  I bought slo-blo fuses.  Now I ordered Synergistic
Research Black fuses.  I don't know for sure if I need fast or slo blo
fuses.  Jonathan at Tone Imports said it's important I get the right ones.  
The Dac is 1.6A and the integrated is a 10A.  Jonathan thinks the Dac is a fast slo fuse while the 518 is a slo blo.  How important is getting the 
correct fuse?  For lack of not knowing  for certain; it's probably safer to get the slo blo fuses.  Is there any difference in sound quality?  Maybe
someone out there owns either of these pieces with original fuses
that could help.



Having removed the WA fuse chip i had on for a week and now reinstalling them.

For believers of this little chip, which cost literally a bag of chips reveals that they fill up the mid regions on the black fuse adding more vividness, upfront  with slightly more apparent highlights of details. Well worth a shot if you have them laying around or even you you have'nt tried them.

This reveals how much change these chips make for an astonishingly low price point.

The black fuse shows it is leaner, less brilliant but well, more spread out or balanced sounding in my setup. With a less pronounced mid frequency balance does does allow more depth to come through. But it is now so clear that it does alone produce a dryer sound without the chip. 

The WA chip is greatly effective, but does seem to be an opposite character of what the black fuse produces. With the chip, you have a much greater midbass presence, richer and weighter (more tube like sound).The Black fuse alone, one hears and feels the lower bass  and a more neutral sound with less colour, this come with the expense of much less midbass. Anyone with a speaker with say 8 to 10" woofer might find a lightening of overall bass, any experiences from the testers here?

I guess it really depends on the sonic balance of ones setup, like any cable change, tweak from mars etc... one really needs to try to see if it fits their preferred sonic characteristic.

Wa chips on the black fuse lightens down and makes more organic sound but in my system is better off without
