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 Dave,

The part that I linked to has a 75 ohm resistor built into it.  And since it is intended for use in video applications (I have used it for that kind of purpose) I would expect the resistor that has been chosen to be suitable for use in terminating the RF frequencies that are present in digital audio signals.

Best regards,
-- Al

Thanks as always Al. That cleared it up.

Found similar 75 ohm BNC terminators on Amazon 4 for $10 with 2-day delivery and 75 ohm RCA terminators on eBay 10 for $10. I am going to give them both a try. Will report back.

Whoa....fuses... This is a new one on me. The fuse in my Pass F5 came from a little box with 5 others for about $2.50 at AutoZone. The fuse sits right above the power cord I snagged at Good Will for one American dollar, with a return policy if I didn't like how it worked, which the clerk made sure I was aware of. 
I can't spend much on fuses because the amp tends to blow them if I'm not carefully about flipping it off and on.

Even standard stock fuses exhibit directionality. A clever fellow can address electrical contact, RFI/EMI, magnetic field and vibration concerns as well. Problem solved!
