Having built a very similar system for my brother, I can tell you this system will sound very good for both music and movies.
- Aperion Audio 5B monitors and 5C center speaker - under $500
- SVS SB2000 Pro - $800
- Yamaha RXA1080 A/V Receiver - $689 at Accessories4less.com
i have a $30k 2-channel system, and I can tell you this combo sounds surprisingly good in stereo and excellent for movies. I think you’ll be pretty thrilled with what you hear. I’d recommend adding some rear speakers at some point as they take the movie involvement and enjoyment factor up significantly. I wouldn’t break the bank with wires, and Audio Envy or Cullen Cable make very good speaker cables, interconnects, power cords for not much $. Hope this helps, and best of luck.
