Same old thread:
nonoise6,405 posts09-07-2017 11:42amA fuse is not a wire. A fuse is used in place of a wire, or interrupts a trace, on a circuit board. We can all agree that a wire or trace should be of very high quality/purity to sound it's best.
A fuse is an over current device engineered to melt, thus breaking the circuit. It's not made to "sound" good. The end caps are usually made of zinc, tin, and aluminum or alloys of them.
The internal wire is usually made of nichrome (nickel, chromium, iron, etc.). It's sacrificial in nature and design, much like MOVs in a surge protector. Why would any "engineer" see it any other way?
Enter modern high fidelity. Would anyone here, in their right mind, use any of the aforementioned metals in their speaker cables? Their interconnects? Their power cables? Their RCA jacks? Their speaker terminals? I think not.
The fuse is a choke point. Nothing happens unless it gets past the fuse.
As someone else has pointed out on another thread, about 85% of what goes on in an amp has a "leg" in what comes after the fuse.
Not all fuses deal with the incoming AC. Some, like the ones in my SACD are in the signal path. There's no way in hell I'm not experimenting with a better made fuse. One that uses rhodium plated copper, copper and nothing else, such as the PADIS fuses. $25 apiece. Better pass through, though not as good as no fuse but not as flat out horrible as some of the cheaper fuses out there.
Some here have said that they just swap them out on a regular basis and show pictures of tortured, aged fuses. A simple look at Wiki says that there should be no damage from minor, harmless surges of current or oxidize or change behavior even after years of service and yet we have proof that the cheaply made ones do just that.
I think what we're witnessing here is a very conservative backlash against progress. The founding tenet of conservatism is stop, not so fast.
Well, that was many years ago since the advent of aftermarket fuses and it took a while for me to catch on to the "trend" but now, after observing it firsthand, I don't see what all the hubbub is about. Hearing is believing and it's so very easy to hear.
As for any argument about "it's just a 1/4" piece of wire. C'mon now. No matter how small and insignificant you think it is, it just messed with the current or signal, and now it's going from one amplification device to another until it gets to the outputs. I'd rather have as pure an original current flow or signal as possible, instead of a corrupted one.
All the best,
Nonoise
