I dont know why analog/audiophiles take such things so hard... unless maybe it reflects poorly on them/their industry? Look at sneakers for hundreds of dollars. Diets. Congress. Every industry has its goofy side. Its the American way to let 'free enterprise' run wild. Free to make mayhem, too.
You can laugh about it or cry about it. Just laugh it off.

But speaker fuses DO make significant thd and thus were put inside the nfb loop to minimise the thd. Now, even that has been eliminated and changed to relay contacts or something else. In pwr supply bypass them with a small value c or use circuit breakers. This is typical of the scammers in all industries.... find a legit issue and turn it into an excessive extreamist do-dad/gizmo. Or just gold plate it. Its the American way. Buyer beware.


Thx-RNMarsh

Exactly so. That's why it's the responsibility of ethical engineers and scientists to point out that these claims are just scams rather than reflexively defending them.

Or just use one of these

Amazon.com: THE SPY SPOT - 7.8 Million Volt Rechargeable Stun Gun w/Built-in LED Flashlight & Holster: Sports & Outdoors

Let's see, 7.8M volts at a "safe" 2mA limit (15,600 W) WoW! . Unfortunately the gap pictured holds off 40-60kV max so these claims are clearly false, sound familiar.

This stuff is old BTW, I had a neighbor that threatened her kids with a cattle prod 50yr. ago. Nice big stick with 6 D cells.

When someone comes up with something like the plastic pizza protector to keep the cheese off the inside of the top of the box we all say why didn't I think of that! That is a product that serves a real need as simple as it may seem. But when someone comes up with magnets to go in your shoes or on your wrist to solve some medical condition we have to look long and hard at any science if any and determine if it is just snake oil. From what Scott and others have said here it looks that there is some truth to how some cabling may have a real electrical component to the design such as the way it is braided in construction. But when those cables start cost 100's to 1000's of dollars a foot then it becomes a cost benefit ratio that seem completely out of proportion to any real gain in performance. At some of those costs I would learn how to braid a couple of wires real fast if I wanted the small improvement that they may have. Does it really matter if someone uses magnesium instead of die cast aluminum in a speaker frame, probably not but it could be used as a marketing tool to distinguish the product. As was just said: buyer beware.
