It is unfortunate the article begins with the false notion of the fuse being there to protect the component. The fuse is NOT there to protect the component! The fuse is there to protect the HOUSE!
Takes about one millisecond to understand the fuse cannot protect any component. Does a fuse stop a tube burning out? How is a fuse going to prevent a resistor or cap or transistor burning out? They will and do all the time. All the fuse does is if this fault causes the component to draw too much current, such as with a short, that could generate enough heat to start a fire. Then and only then does the fuse do its job by burning out, which otherwise could result in a fire.
Other thing unfortunate is fricken Goolag translate:
Every issue of Chinese and foreign audio magazines is always uninterrupted, with unremitting spirit to face and solve, with strong comprehension, can draw inferences from one another, and many audio mysteries can penetrate the mystery.
Clear as mud, but it covers the ground.
After chewing the text, I feel that some of them are illusory and vague.
I'll say.
This part though is interesting:
metal activation technology: increase the amount of electrons flowing in molecules per second, and the larger the increase, the better the effect, which can increase the dynamic range and sound density.
Okay, well electrons are subatomic particles. Molecules are combinations of atoms. So conflicting scales. Molecules do not flow, only electrons. You guys caught that one, right? Once again clear as mud. But at least we get the idea, there is some underlying reason why these things are so much more dynamic and clear.
I did find one useful bit of possibly solid information:
Series, respectively, A-Analog for analog equipment; D-Digital for digital equipment; S-Sub-woofer for active subwoofer; V-Video for video equipment. The four series are tuned to make the equipment unique effect.
Is this correct? Or another translation snafu? Because when I ordered mine off tweekgeek.com there was size, color, and fast/slow. That's it. No A, no D, no S or V.
Awful lot of reading to wind up with more questions than answers. But, thanks.
