I am setting an HT and I am buying several component, S-video, optical, and audio cables, plus some speaker wire. I have read several posts that have directed me to AR. But there are several lines product lines out there: HT, PROII, and Master. In addition, there is the stuff you can find at Best Buy. The cables at BB are blue in color and start with the prefix AP or DA, as in AP053 for the sub cable. The same cable on the PRO line is PR153. Is this a way to confuse customers or is there a difference in these lines. Maybe the DA series compares with the HT, whereas the AP compares to the PR. This is getting to be fairly confusing. Thanks for your help.
