Monster Cable news in USA Today is very funny - but it is presented as News! Pretty poorly written article in USA Today, with no questioning of whether Monster really makes any sense. The comments people posted are more to the mark, that is where some questions are being raised.
"Oxygen Infused Cables" and some such thing, and people shell out 100s of dollars for such gimmicks. Well, a sucker is born every minute, so good for Monster to soak up the excess money some people have floating around.
There is absolutely no need for the way Monster and other high end cable companies make audio/video cables - metal conducts electricity, for analog the key issue is the gauge of the cable (get thicker one for higher currents), and for digital - hey, even easier - either the bits get from one end to another, or they don't and any decent cable will work fine.
Sure, buy Monster if you like the to overspend, but don't buy it because "it conducts electricity better"! And there are certainly crappy cables, good cables, very good cables, excellent cables, and way-out-there-with-magic-powers cables, and it is best to avoid that last category along with the first.
Lot of good stuff on the web such as Monster Cable Sucks! and CNET HDMI Cables along with the kool-aid drinking gushers.
