So I am upgrading my theater system from a Bose all-in-one that I bought back in 2004. However I run into a bit of stumbling block and I am not exactly sure where to go. I recently was able to get my hands on a Denon AVR-X3200W and a BiC American F12 for a relative good price. However, I am unsure on what the next step is. The current room is rather small (10x15) but we will be transitioning to bigger rooms by the year end. My initial plan was to build the sound system incrementally. Starting at 2.1 for now, and then going 5.1/7.1 once we get into the bigger rooms. The research I have done points to saying that I should get shelf speakers first for now to complete the 2.1. Then when we get into the large rooms, I can add a center speaker and two floor speakers while moving the shelf speakers to the rear as surround speakers. Is this feasible? Any suggestions on what kind of speakers will go well with what I have? I am partial to the XTZ 95 series (http://www.xtzsound.us/shop/us/Speakers/95-series/xtz-95-24-black-matt) as I have read nothing but glowing reviews about them but since this my first time building my own theater system, I am a bit hesitant in pulling the trigger. This also represents the max my budget will allow at this time.
