Hi, I was not sure whether to post this in the speakers forum, or in this one, or both, but decided to try here first.........I am hoping to start putting together a surround sound system and am looking for some opinions. This will be my first system, so I am not looking for the best there is, but I am looking for the best that my (currently limited) budget can afford. I want something that I can use for both music and movies, and since I am on a budget plan to buy various components over a period of time. The first items I want to buy are going to be a receiver and floor standing speakers. So with a $500 budget, what do people recommend? I have looked at some Infinity speakers (Primus 360 $175), Onkyo (TX-SR504 $220), Denon (AVR-1507 $300) and Sony (STR-DG600 $200) receivers. Also, since I will be using the system to listen to music. Should I invest in a dedicated CD player? or will a DVD player be ok to use for playing music CD's? Thanks.
