AVR vs seperates

Trying to figure out which way to go. My HT room is setup for 6.1 with a Zone 2 (4pair of speakers throughout house for background music/entertaining) My main purpose for setup is movies/sports t.v (95% of time) and 2 channel (5% of time) My two main speakers are Martin Logan Ascents (200W@4ohms) center is Martin Logan Cinema (200W@4ohm) rear surrounds and rear center are inceiling SpeakerCraft AIMones (100W@8ohms) Haven't decided on a sub yet (open to suggestions. So with that info, can anyone recommend which way to go to do movies right? Budget around $2000-2500. Thanks.
