Hello, First time poster and frankly first time potential buyer of an audio receiver that isn't a book shelf system. I have been looking around the internet for a few weeks now attempting to find a decent system that won't blow away the savings however I have certain requirements due to usable space in my living room. The room is 16x20ft and has multiple entry and exits since it's the center of the house. The 16ft span is where the entertainment center, coffee table and couch sits. The couch sits about 4ft away from the back wall and 8 ft from the 42" TV we have on the entertainment center. Due to positioning and entrances into the room a 7.1 surround system utilizing all 7 speakers is very difficult and simply not doable. I have looked into 6.1 systems but simply put companies do not seem to make 6.1 systems anymore. So I looked alternatively into 5.1 surround systems but many do not have the extras I would like to have such as more component and at least 4 HDMI connections and a few other things. I have narrowed down my search to the following two systems. One is much cheaper than the other one by about $250. Onkyo HT-S5300 - $500 http://www.onkyousa.com/model.cfm?m=HT-S5300&class=Systems&p=i Onkyo HT-S7200 - $750 http://www.onkyousa.com/model.cfm?m=HT-S7200&class=Systems&p=i But before I get a 7.1 surround sound system I need to know if I can use the speakers in a 6.1 or 5.1 surround sound schematic and not use the 7th speaker due to the flow of the room. I am not willing to do extreme wiring modding through the attic and in a wall just to get a proper 2 side surround speakers! So I would like to only put speakers behind the couch against or mounted to the back wall. Nothing I can find in the product descriptions from the Onkyo website or any of the other dealers have any information in if I can hook up the speakers in a 6.1 or 5.1 way and have it work correctly. I already plan on buying larger gauge speaker wires probably 18-Gauge So for someone who listens to music and likes to watch movies on DVD and in the near future blue-ray but for the most part watches mostly television shows digital and HD; Which of these systems would be the best bang for the buck and have the requirement of a 5.1 or 6.1 surround sound option? Thanks in advance for your advice.
