I've been reading reviews about the Kenwood HTB-504. I really need a basic surround sound setup and this seems to be the best one for the money. I'm considering buying it within the next few days (after I do some comparison shopping and allow my own ears to hear a few different systems). HowEVER... In several reviews on www.audioreview.com, I have noticed some people claiming that the speaker wire that comes with the 504 are crap. Some have mentioned getting a (number)-gauge speaker wire to replace those that come with the system. How can I determine the quality of speaker wire via the gauge numbers? Is it the higher the gauge number the better or is it the lower the gauge number the better? What else must I consider when replacing the speaker wire? Also, are there any other wires/cables I may need to replace the ones that come with the Kenwood HTB-504 system?
