I currently have a somewhat thrown together system. It started out as an Insignia box system from Best Buy. Since then I have upgraded the center channel to a Polk CS-10, the reciever to an Onkyo TX-SR608 (7.2), and added a Jamo SUB206B (running 2 subs now). My inclination is to buy some decent bookshelf speakers next that I can swing to surrounds down the road when I can afford some high quality floor-standing speakers. I was looking at some Polk speakers such as the Polk RTI-A3. I use this system for daily Netflix watching, DVDs, and music. I think the sound quality for music is the most important thing for me. I am really curious as to the next couple steps/purchases I should make to improve this system for 1.) music and 2.) movies and tv (sports)
