Hello I am a newbie and NOT an audiophile. I was in the market for a HT sytem and I bought a Polk speaker system from our local audio store because it was on a good deal and the sales guy was raving about it. That is how much I know. The speaker package is 2 Polk Monitor 30s 2 Polk Monitor 40s One Center Channel Polk CS1 One Polk PSW10 Subwoofer Can you audio gurus kindly suggest on the following 1 - What receiver should I buy to drive these speakers. It is 5.1 now but I will try to expand later. 5.1 receivers are fine but 6.1 or 7.1 suggestions are also welcome. Please suggest a high end and low end receiver if you can! 2 - Also, should I replace any components of the above package with an upgrade in speakers, center or subwoofer to get better quality. (I can always sell the above components individually because they came in individual boxes) I live in an apartment, the TV room is 18x18 but 22x22 if I include the dining room and kitchen which are kind of combined with this living room. I am looking for a good value receiver but if you think there is going to be a quality difference and long term value please suggest high end stuff also. If not something in the same range as the above speaker system would be fine. Thanks a lot for your help! I promise to contribute when I become an expert on this stuff.
