So done with audiophile fuses


The journey started with a medium priced ($50) fuse in my power supply.  A failed rectifier tube blew that one out.  Not a fuse problem.  Next up was a blue fuse in my pre amp.  It blew and was not caused by a pre amp problem.  Apparently they sometimes are more sensitive and it was replaced by an orange fuse two values higher.  Things were going along fine.  I replaced the pre amp with a newer version of the pre amp and it has the same fuse value.  Five months latter (today) I turn on the pre amp and nothing.  it's a five month old pre amp so I suspected that it was the fuse.  Sure enough, I replaced it with a ceramic Littelfuse of the lower correct value it works fine.  No more wasting my money on unstable fuses for me.

Isn't Wyred the company that took a state of the art modern AKM DAC IC and managed to turn that into a $4,000 DAC that just about matched a mid 1980's Philips based DAC in performance?  
Do you see Pass, Curl, Cary, Mcintosh, or any of THOSE folks coming out of NASA, or NEC, or the FDA, or Brain or Heart surgeon Professorships? WTF.

NEC? FDA?  ... You should have stopped at NASA, though they have had their fare share of failures ver the years.

There is some complexity to modern stereos especially when you consider what is buried inside a sigma-delta DAC, or the latest Class-D, or the semiconductors powering the system, or the capacitors. However, most are just throwing together building blocks, but it took 100 years for people at THX to come up with some new architectural stuff to reduce SNR/THD.

The top speaker/driver companies are no dummies either. There is a lot of good science and engineering there too.

Most of what NASA does is applied. The real research goes on in places like JPL, and university labs.
The job of a safety fuse in a component is to protect the cord that is connected to that unit in case there is a serious short in the unit.  Additional fuses may be added to protect the component itself.  Where safety items are being discussed, its is dangerous, ill advised, unwise to comment where you lack knowledge.
Jhills, safety requirements for most equipment includes a fuse or equivalent unless there in innate current limiting. We are talking things like UL. That fuse is to protect the cord from overheating. The equipment if safety approved or at least designed properly is already in a fire resistant enclosure where needed.
You continue to amaze, astonish, and sadden me with your willingness to argue about a critical safety issue with which you have no knowledge. While in the US, an NRTL test is not technically required, in much of the world, an equivalent is required, or self certification that states you have met the technical requirements of the related standards. In the UL, whether you have UL or not, you are LEGALLY required to meet NEC codes, local laws, etc.  (which may require NRTL testing to plug it in) and DO require fusing as applicable to protect things like line cords which your breaker box is not responsible.


Just stop ... don't start typing a reply unless you are very familiar with this.  This is a safety issue.
