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 you point out one person on here who has actually done a blind test on a fuse?  No. They all have "superior" hearing and could never fool themselves .....

I would concentrate on the mids and highs only you will not need special fuses for the bass frequencies nearly as much if at all and try to see if you can find a dealer to send you a selection of different fuses that you need and try them out it could make a real difference depending on your amp and entire system.

The truth is folks, fuses in general, are bad for sound. They limit current, and are a band aid for the purpose of the protection of gear. This is the fact. As theaudiotweak pointed out with transformers, they produce mechanical vibration ( and other things ). Take any amplifier design, and isolate the power transformer ( s ) from the chassis ( cork and rubber, a simple mouse pad ) can do wonders. I use sheets of Dynamat, if I have the room within the chassis, and it is incredible the cleanliness of the sound, with this one tweak. Of course, I dampen the entire chassis, including those horrible heat sinks, which ring like hell ( they all do ). Everything makes for sonic improvements, as I have done for myself, and many others. Doing and listening, is the only way to know. And back in the day, when components did not have IEC inlets, I replaced the cords ( soldered ) to better, heavier gauge cords by the big cable manufacturers ( Belden, Southwire, as examples ), and incredible sonic improvements, every time. If anyone opens their gear ( inclusive of fuse replacement ), I recommend to be careful, and hope you know what you are doing. I take zero responsibility ( if anything bad or dangerous is to happen ) for recommending these things to anyone who wants to tackle them. I have nothing more to say, at this point, on the fuse topic. Enjoy, and be well.

Fuses do NOT contribute to the sound in any way AT ALL.  They will keep your insurance company happy however.

Do not believe the superhumans on this thread who claim they can hear a difference.

For courtesy to the believers, I have tested them many times.  Not even the most sophisticated measuring equipment saw any difference.

Just keep the fuse contacts clean (otherwise, it generates heat, and still does NOT make any difference to the sound) and spend your money elsewhere.

There is only resistance, capacitance & inductance in everything electronic.  There is no other magic.
