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?

 is there a fuse made that has a built in fire extinguisher?

I don't think so, but there is one that comes with a 30 day free psychologist.

"further down and a bit to the right, just under where the power cord emerges from the panel, the photos I’ve looked at say something like "for continued fire protection use original fuse type and rating only of MDA-10."
Al, I appreciate your research into the correct type of fuse. I didn't see the instruction on the back of the amp since I have a conduit on that shelf to separate cables.

 My first move will be to pick up some Bussman MDA-10 fuses and return the amp to baseline. Thanks again for the info.

BTW, all contacts on my amp were cleaned not very long ago, and I will clean the fuse holder.

Lowrider, it looks like the MDA-10 may have been superseded by the MDA-10-R, which is very similar except that it is lead-free and complies with the European RoHS (Restriction of Hazardous Substances) requirements.

As you may have noticed at the link I provided for the MDA-10 Digikey has no stock under that part number, but that page refers to the MDA-10-R as being an RoHS compliant replacement, and the technical specs on the two parts look very similar. The page for the MDA-10-R shows thousands as being in stock, for $1.58 each in small quantities.

Digikey is a distributor of electronic parts, mainly serving industry. But they have no minimum purchase requirement for most items (apparently including this fuse, since a quantity 1 price is indicated for it), and every transaction I have had with them over the years has been prompt and flawless.

Best regards,

It sounds like the SR Black line of products are improving detail to a point that is not ideal for your system. That is my emotional response to my son's new 4K TV compared to my Panasonic Plasma TV. Too much detail that for me is distracting. He  loves the added detail.
David, I feel the same way regarding video.
As stated earlier, I got the same highly-detailed sonics when using the SR Black power cord. But the lush, sumptuous sound of the SR is addicting.
Regarding the Isoclean fuse, there's a very good review written by Albert Porter, although he's probably moved on to some other tweak by now.
