Audio/Video myths and mysteries

Ok, so I have run across a couple of common audio opinions on here that I feel are very common and not true. I am asking for anyone that has questions about audio and video stuff; things like does it matter if you run RCA's next to the power wire, or how long can the ground wire be, ask them here so that we can get a good source of information to search upon.

I also want to put it out there that, while I am certain about my ideas and will argue them, I have an open mind. If someone can prove that an idea that is not consistent with mine with reason and logic (and maybe some solid physics) I am open minded and will gladly subscribe to their option.

As long as things stay civil and logical, I am all for good discussion on these various topics. Also, not sure how much legs this topic will have, but I think it is worth a shot. If it is a terrible idea, then oh well, I put it out there.

 

There is thread similar to this that Mr. Marv started.
