FUSES, Finally!?

     I have been adamant about avoiding special fuses, because of the lack of empirical studies.  Here is my question:  What would be something not too expensive that would be a good start.  I use three dual mono Audire amps (for Woofs, Mids and Tweets, and Subs, each of the six channel having four fuses.  I would not not want to spend thousands, even if I could, just to experiment.  My heat sinks do unplug, along with the outputs, and I could try just one channel or one amp.  Paul of PS mentioned what they use, and that might eventually be a possibility, but what do you guys (and gals?) think I should do, to just to convince this ageing skeptic?  Also, each channel of my amps has one single, dedicated computer chip that regulates the filling of the 4 26,000 mf caps (per channel), which might make any difference less than a design that allows a flood of electrons into the tank, presuming that might matter.  DanV

Can always rely on a fuse thread for some entertainment. WOW guys really?

If you don’t believe fuses can make a difference, great you have eliminated the issue and can move on. That is, PLEASE MOVE ON. Why waste your time belittling others when you know it’s impossible for a fuse to improve the sound.

I have posted this challenge before. It’s FREE: Swap direction of a stock fuse and listen. If you hear no change count yourself lucky and walk away. If you do hear change then try some good quality returnable fuses. Do they make a difference? - - of course they do, everything makes a difference.

For a reference, temporarily replace a fuse with a clean copper tube and listen to the sound then find the fuse that sounds most like no fuse. I am running my power amp with bypassed fuse which sounds better than any fuse I have tried. It’s staying that way.

@oldhvymec, I like your amps. Jim Bongiorno was one of audio’s greats. I still own one of his Son of Ampzilla designs that blew up at a party 20 years ago after somebody spilled the whole bowl of punch over it. I kept the chassis and rebuilt it with a Neurochrome kit. This is the amp I am running fuseless.

I suppose I should add: Don’t try this at home.
