Synergistic Red Fuse ...

I can tell from listening session to listening session what’s going on, but do I really hear things accurately? Has it improved overnight ... or not? Or, has the change actually moved things backwards a bit?

Not only that but can one be sure a change heard over the time is a change in the fuse? There is a tendancy to attribute a change over time to the last thing changed but certainly there is no rule that says that is necessarily the case. I hear differences day to day with no changes at all to my gear. Is it me? The gear? The weather? The power? All the above? Who knows.

Whatever its fun trying to figure these things out I guess.

OP my ARC sp16 pre-amp uses a 3 amp slo-blo fuse, apparently same as your ARC. I appreciate the offer but hold onto your red fuse. Fuses can blow (that’s what fuses do) and its always good to have a spare fuse. Offer much appreciated though.

I have a few significant enhancement projects already going on currently with my stuff. I’m refoaming some old Boston A40 series II speakers I have sitting around and working on getting digital USB feed from my Iphone 6s and tablet to my mhdt Constantine DAC. If I had more time to dabble I would probably take you up. Thanks again for the nice offer and gesture.

I’ve been thinking, my Hegel H30 uses a 15 amp slo-blo so theoretically if on a 15 amp outlet, the breaker will trip and don’t need a fuse ... just hard wired it. But since it’s on a 20 amp line, MAYBE not a good idea. I’m just speculating and not bypassing the fuse.

I think you’re right to not count on the 20 amp breaker providing protection comparable to a 15 amp fuse, Kng, and I would say the same thing even if the breaker and outlet you are using were rated at 15 amps. A circuit breaker will generally take MUCH longer to trip than a slow blow fuse, at least in situations in which the overload is not extremely great.

Good point Al, another good reason not bypassing the fuse.
Thanks!

I tried the Red fuse in my Magnepan 1.7i's and even burned them in for 200 hours.  I couldn't really tell a difference.  Do the fuses make a difference in preamps/amps/sources?  

These fuses, and aftermarket fuses in general, intrigue me. What is it about them that improves the sound? I am guessing the fact that there there is so much room for improvement means that stock fuses and fuseholders are an impediment in some way to the incoming AC.

In that case, has anyone ever tried to bypass the fuse and wire their gear directly to the AC? I would imagine that configuration (while maybe not being the safest) would be the "holy grail" in the sense that no passive component + connectors can really improve upon a straight unbroken wire.

Or maybe these fuses have some other method of operation (similar to Bybee filters) that enable them to impart their "magic". In the end, I guess one must remain open minded. I use HFT fuses but I cannot really say with authority whether they made any difference. I look forward to trying these out sometime in the near future.
