Ultimately it's rigged for the !@#$% lawyers.

Coke would have a case under "dilution," seeing as most everyone on the planet knows Coke, which makes it a "famous mark." Monster has used this same "dilution" theory in most all of their cases, though no court has ever ruled that "Monster" is a "famous mark" for Monster Cable. Nor would they ever likely receive such a ruling as there are a bazillion non-Monster Cable trademarks out there using the word "Monster."

So if I trademark "Satan" will he do my bidding... might have been beaten to that methinks.

You can also use this for more general stuff, they use it where |I am working at the moment, and also the fancier stuff shown earlier, its very educational for me:

Stuart, please enlighten me why this should be so....this is your quote "Where would you get that curious (and totally incorrect) idea?".

Thanks, Dan.

Mr Martin,

where lies the crossover point, in terms of wealth, in your opinion ?

Typically, when I run into a problem, I break out my multimeter, my scope, a spectrum analyzer, and a signal generator and start getting data. Without data, you're shooting in the dark, and I can't really do any better from 12,000 miles away.

But this would give a correct EQ for circumaural phones only, no ?

I would love to see some real data regarding ferrites and audio, also ferrites are designed for different frequency ranges (generaly used to solve problems with quite narrow range of frequencies, and all in the MHz), and often used to stop equipement transmitting signals into the ether via them nasty cables.
Though if I remember rightly standard ferrites were canned by the audio press, but Audioquests RF stoppers were deemed OK (these cost about a zillion times the cost of standard ferrites).
If people near you are using power line communications then ferrites can help limit this mains borne EMC from entering your system.
As said I would like to see some empirical data on ferrites and audio, and for different types ad frequency range of ferrites, because I wonder whether this is another overrated problem like "skin effect" at audio frequencies...
