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?

Bill,
Since you've used breakers in your numerous modification projects I'd assume that it is relatively easy to accomplish.  If this is true why the continued dominant use of fuses in audio components rather than breakers?

I too am curious why breakers are not more widely used. Are the trolls okay with breakers, or are they voodoo scam snake oil too? 😉

Discussion of the use of circuit breakers in audio components can be found in the following threads.  The bottom line would seem to be that it may be suitable and beneficial to use some breakers in some applications but not in others, with breaking time being one of several significant considerations:

Also, use of a circuit breaker in a DC rail application may be problematical in many cases in terms of where it is located and how it is wired to, with the possibility of noise coupling to or from that wiring having to be addressed.  

Finally, I would imagine that in many cases a factor is that designers tend to go with approaches they have used previously, and are familiar with, and do not require significant time for evaluation and experimentation in return for sonic benefits that may or may not occur.

Al,
Thanks for providing the links, I'll read them later today.  I realize that there is a pro and con argument that can be made for virtually any choice made regarding audio products.  It'd be interesting to know what factors cause Nelson Pass to avoid fuses and utilize circuit breakers.

That would be interesting. Tried google search and came up empty.

One benefit would be anything done differently is a unique feature and helps differentiate one product or product line from another.

Also I’m sure not all breakers are created equal just like fuses however I would expect a good quality breaker circuit to be inherently more costly to implement than most fuses.
