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?

Hi Keith, 
I honestly don't know enough about your digital source  or the fuse chips to give any meaningful or informed recommendation. 

I would think that Krell can answer your question concerning their amplifier fuse requirement.

Gents, 
If your speaking about a fuse that has 2 blades like a car fuse I feel that such a design is less of a compromise of performance when compared to a standard glass fuse. Tom

That's interesting, Tom. How so?

What size/type of fuse does it take, and is it power cord socket?


Mribob, It's a 15 Amp slow-blo. It's a miniature fuse holder that requires a screw drive to open and close. Mine was loose so the cover spins when taking it off or on. I replaced it with a high quality Bussmann panel fuse holder but accidently bought a larger size. I'm very meticulous so no idea how it happened ... When Hegel tech returned the amp, I thought he installed a different fuse holder so ask and it was mine.

Sometimes things have ways of working out ... turns of SR RED offers a large size 15A Slo-blo but not smaller size.


The $64K question - are no fuses better than Black fuses?


Yes, Reason ARC and CAT use resistors and NOT fuse to protect power tube failures. People always criticizing ARC and CAT but especially ARC so maybe now they understand.

The SR Blacks have been in the CDP and pre since Saturday, with a total of maybe 30 hours use on them (the CDP is left on all the time while the pre is not), so semi-broken-in at this point.

I'm waiting for the last bit of stridency in the upper mids to chill out, but other than that I'm a very happy camper and they are doing for my system pretty much everything oregonpapa says they do for his.
