aND ENGINEERS tend to be perfectionists , but in the real world signals arent really that delicate.
Hes talking about broadcast quality, I AM TALKING ABOUT PLUGING a cheap dvd player into a tv set.
LET ME PUT IT THIS WAY, IT WOULD TAKE A BROADCAST ENGINEER
to notice a difference, and he'd probably need a scope
It's not so much that you are misinformed that's the problem, I am quite happy to let you live with the consequences of your own beliefs. It's that you insist on passing on wrong information to others.

The composite cable connections on modern HDTV are there to produce a picture that is as good as broadcast quality, you won't find the three cable scheme on any standard definition TV. It's that picture improvement that we paid for by buying an HDTV and an upconverting DVD, throwing it away for use of a wrong cable makes no sense.

Yes, an oscilloscope will easily show the problems with audio cables used for high bandwidth signals. Passing high bandwidth analog signals over an uncontrolled bandwidth cable is a recipe for bad results. The problems created by uncontrolled impedance cables are also quite easy to see on a TV screen. One of my job assignments was designing television circuits, I learned how to see the problems on the screen, the oscilloscope merely confirmed what I already knew by looking at the picture.

It's not that an audio cable will not pass 5 MHz, it's that it doesn't have a flat frequency response to 5 MHz when a coax cable does. Since coax is often cheaper than "good" audio cables advising people to use audio cables is just plain stoopid.

My apologies to the rest of the forum members, its that determined ignorance, the insistence on stupidity, that "you can't make me learn" attitude, that gets my goat.
