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

Hello theaudiotweak, I'm right here, in LA. It's just that I've sourced low cost fuses from Europe and Asia before so it's no biggie to go there. 

What I didn't know is that those breakers work over here. I've know of them for some time but thought they were proprietary for use over in Europe.

All the best,

I saw a similar breaker and fuse combo on a German website years ago..and now backround photo of something similar on the Chinese site selling the $2200 fuses. The breakers if they fit would be most welcome in my audio room breaker box. I will find out more and let it be known. Thanks Tom

Here is what I saw..they appear to be physically to small for most uses I have..

The fuses shown are described and look much like the Acme fuses
sold out of Seattle. Inexpensive cryod silver and ceramic version  which actually sound very good. I would go to the next higher value if your unit has a lot of in rush at turn on.

Yup. Those are the ones I saw before. I always thought it’d be nice if they could be used here, stateside.

And, thanks for the heads up on the Acme Audio fuses. Their price is very reasonable so I bookmarked it for future reference. In fact, I may try them soon.

The main reason I have been such a fuse skeptic is that I assumed the fuses were not in the audio path.  The ones in my amps certainly do not seem to be.  I did used to use in line speaker wire fuses for my Phase Linear 400 powered Advents, but that was nearly 50 years ago.  The NASA Apollo circuit breakers I mentioned are really only used as power switches.  They are really robust.  I do agree, right or wrong for now, that the bass should be least affected.
