I just hooked up a long (around 25 feet) of Samson's Super Duper Hi-Fi Digital Coax Platinum Series Cable (bulk, quad shielded coax with compression RCA connectors, hand assembled by my five-year old to keep labor costs down) connecting my DVD player to my receiver.

What exactly will I hear, or not hear, if there's interference or a poor RCA connection to the cable?

Since the cable is carrying 1's and 0's, will I hear dropped sound? Pops? I need to know what to listen for in my new cable, if I hear a problem, I'll need to address some QC issues. Might even have to send my kid to fetch me a beer, while I have to do the darn RCA fittings myself.
