I'm new on this forum, and I've tried the search forum, and couldn't find anything of interest to answer my question. My question is: Is paying extra money for gold plated or monster cables for Audio/Video worth the money? I have acoustic audio cables for everything right now, and they seem to work good. Is there any evidence or any diffrences visually or in sound? I have a 52' HDTV plasma, 6.1 yamaha surround sound. I use optical as my main audio cable. Any help would be appreciated. I'm mostly looking for supported facts or data. Thank you!
