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

love the directional fuse guys the best, because it is akin to wearing putting a swastika tattoo: It lets people know where you stand. As I have noted before, electricity from our wall outlets, interconnects, speaker cables, as well as sound WAVES from our speakers, does not flow like water; it "vibrates" back and forth".   If AC wires, including audio cables, were truly directional, they would restrict half of their functionality







Energy flows from the power source to the load, so your understanding is only partially correct.

Fuses do NOT contribute to the sound in any way AT ALL.

Okay. Wire does not contribute to the sound in any way AT ALL. I guess. If you say so.  

Just one question: Then what does?

if you use a power conditioner/surge protector could you just remove the fuses?

NO.. Fire protection, and equipement protection first.. You can get in trouble if you’re not careful.. Usually there is a 2-5 amp slow blow to get a valve amp going and a .5 -1.5 quick blow, for a tube failure..

LOL I’ve bypassed fuses and really seen an improvement too. It usually had to do with low impedance loads like 1-2 ohm loads and BASS drivers.. Me pushing amps for all I could get, before big class Ds..

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.
