For the last year or so I've been using a crappy surround system but and am now ready to upgrade. I've got about $850 to spend on a decent 5.1 system. I already have a Yamaha HTR-5560 so I don't need a receiver. Anyway, I would just like to hear opinions on what would be best. I prefer tower speakers for the fronts so that I don't have to mess with speaker stands. The speakers will only be used for movies, no music. Can I find a decent system within my budget?
