Unsafe Power Products

[amirm]

OK, so we won't ever converge on whether power tweaks do anything. But one thing I hope we converge on is safety. Take a look at the instructions on how to build this "lessloss firewall" AC pass through box: http://www.lessloss.com/docs/FW_Installation_Instructions.pdf

The ground wire is passed through. Note how poor the solder job is on the green+yellow wire. It is just a blow or bounce away from coming loose. If it just does that, you lose your safety ground. If it moves further and touches the hot, you just energized the whole chassis of the product!!!

Notice how there is nothing keeping the left cable from being pulled out other than whatever pressure the wood case puts on it. And wood being wood, will expand and contract with humidity. The ground wire needs to be a lot longer and fastened on the side to keep it from being pulled out.

And that jumble of wire connected to hot and neutral terminals don't give me confidence either. Any of them could come loose just the same.

Don't worry, it sounds better that way.

The "nitty-gritty" of such a dangerous design is that Lossless may very well be Lifeless.

Would it be better also to build it inside a fireproof metal box instead of the wood one showing up in that above picture?

At least use a proper plastic box designed for electrical work (available with built-in cable clamps etc). If you use a metal one you have to bond it to the earth wire, just more hassle because it has to be done in a code-specified way (crimped lugs, star washers etc).

Why not? All it takes is one proper blind test. Or for those who understand that science trumps religion, a comparitive measurement of the audio device's output with and without the "power product" connected.

Take a look at the instructions on how to build this "lessloss firewall" AC pass through box:

What does this piece of junk claim to do? From their web site: "No caps, no inductors, no resistor, no fuses, no diodes." So what does it have? I also saw: "No hint of 'digititus;' relaxed, natural and fluid sound; dynamic to the lowest bass." What does any of that even mean? How can otherwise sane people buy this bullshit?

And, oh yeah, their soldering is atrocious.

Mu-Metal.

Ok, I did.

That build wouldn't stand a chance passing our local regs; therefore any potential insurance claims, otherwise proved to be caused by the device, would certainly be questioned ...
