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?
One issue to consider is that Singapore's electricity voltage is 230V whereas the voltage for the U.S.A. is 120V, therefore I have no idea if this would affect the fuse values in the Sony in anyway? Perhaps someone more qualified can hazard a guess? In any case, you can confirm after popping the fuses out and using a magnifying glass to read the values.
Les, The voltage rating of the fuse is a non issue in the USA. I'm happy that you are having such success with the Black fuses. Asia, Europe and North America, this thread has reached far and wide.
