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?

Charles, I don’t know why many builders don’t use film caps in the power supply? Why they don’t use better internal wiring? Why they use such long signal paths? Why they don’t use breakers? Why many builders think one part sounds the same as another as long as both are in spec and think boutique capacitors/resistors and the like are snake oil? Why do we still use conventional binding posts instead of clamps that clamp the output wires to the speaker cable? Many more audio questions I wonder about in terms of tube gear design.
If my memory serves me right and we had a LONG debate, Atmasphere states 95% of his amp and preamp designs are based on specs. Any builder voices their design is incompetent. So I guess cap, wire ... with the same spec will work so probably reason inferior parts are used?

To everyone posting here:

Do any of you like coffee? I do. I love really great coffee. Its the only coffee I'll drink.
I love coffee. I buy most of the coffee from Trader Joe's and settled on French Roast and Italian. I use a burr grinder and French press ... I guess next step is roasting my own coffee ...  I'll let you know how it goes :-):-)  

BTW, the circuit breakers Paul Weitzel uses are all mil-spec.  I still have several in my basement.   Paul said never seen one failed.  


tommy, no mater what side of the fence you are on, I think the reason non fusers keep coming back to this thread is the curiosity of reading about people hearing differences that knowledge experts have explained are not possible.

Moving on to another fascinating area of controversy; tube rolling. My Audio Note Kit 1 DAC uses a single 12AU7 type tube in the analog output stage. I had been using a NOS (80’s vintage, I think) Tesla ECC802S, which I thought was a pretty good tube. Supposedly, they were made with the original Telefunken tooling. I swapped it out for a low noise, low microphonics tested, 50’s-60’s vintage, Telefunken I acquired from Andy Bouwman at Vintage Tube Services years ago. I was not really prepared for how much better it was. I think the black fuses, along with other recent changes and tweaks to my system, have increased the resolution such that the differences are easily discernible.

If you are interested in exploring the difference really good NOS tubes can make, I highly recommend Andy:
